Installation General Guidelines

Pre-Installation

Your expert installer should evaluate the jobsite before the ALSTON hardwood flooring is delivered. This includes detecting and correcting possible jobsite and subfloor issues that might affect the hardwood flooring once it is delivered and installed.

ALSTON also recommends that the Owner remove valuables from the installation area, including but not limited to, artwork mounted on walls, fragile decorations, and other personal items. ALSOTN INC. is not liable for losses and damages, accidental or otherwise, caused by the Installer and/or sub-contractors.

ALSTON’s manufacturer warranty does not cover flooring failures resulting from a failure to perform required pre-installation and installation procedures, including but not limited to, Owner/User/Installer negligence, accidental or otherwise.

Jobsite Conditions

Owner/User and Installer are responsible for ensuring that exterior grading is complete with surface drainage offering a minimum drop of 3" in 10' to direct exterior water sources away from the structure where the flooring will be installed. Owner/User and Installer should ensure that the “grade” where the hardwood flooring will be installed is appropriate for its construction:

• ALSTON Hybrid-solid engineered hardwood floors are approved for below, on-grade, above-grade installation. Below-grade installations require a floating installation method.
• ALSTON Solid hardwood floors are approved for on-grade and above-grade installations and should not be installed in below-grade areas such as basements.

The jobsite should be enclosed and climate-controlled. HVAC systems must be fully operational with a consistent room temperature of 65°F - 85°F and relative humidity levels of 35%-55% for minimum of 3 days before the flooring is delivered or installed.

ALSTON hardwood floors are not recommended for use in areas subject to repeated moisture exposure and possible water overflow areas such as kitchen, bathrooms or laundry rooms.

To eliminate potential trade-related damage, ALSTON recommends that its hardwood flooring be one of the last jobs completed. Drywall taping, wall painting and other “wet” work should be completed and thoroughly dry prior to installation of hardwood flooring.

Subfloors Conditions

The quality and preparation of the subfloor is critical to the proper installation of ALSTON hardwood flooring.  Subfloors must be structurally sound, clean and free of all debris, staples, nails, wax, grease, paint, sealers, old adhesives and other substances that may prevent a successful installation. Subfloors should be level and flat to 3/16" per 10' and must remain dry all year round. Subfloor moisture content must not exceed 3.5% for Concrete or 13% for Wood, Plywood or OSB/Particleboard.

Acceptable Subfloor Types

• CDX Plywood
• Concrete – With a minimum compression strength of 3000 PSI
• OSB/Particleboard – Must be structurally sound. Floating and Glue Down installations only.

Wood subfloor must be:

• Clean, dry and well secured.
• Nailed or screwed down every 6 inches along the joists to remove squeaking.
• Leveled with high spots, sanded down and low spots filled with a leveling compound. Leveling material should provide a structurally sound wood subfloor.
• Properly test and document moisture content prior to wood installation.

Concrete subfloor must be:

• Clean and free of paint, sealers, adhesives or other debris. If present, concrete sealer must be removed by grinding and sanding.
• Fully cured for at least 60 to 90 days prior to installation.
• Installed properly with minimum 6-mil poly film moisture barrier between concrete and ground.
• Dry all year round. Do not install hardwood flooring over concrete if it will not remain dry at all times.
• Properly test and document moisture content prior to wood installation.

Subfloor Moisture Testing Requirements

Moisture testing of the jobsite and subfloors is critical to a successful hardwood flooring installation. Visual checks are not reliable.

If subfloor moisture exceeds acceptable levels, the source(s) of this moisture must be corrected before the hardwood flooring is delivered to the jobsite.

Excess moisture detected in the subfloor requires the use of a moisture barrier product, including but not limited to, PVC vinyl sheet (with felt-backed and vinyl wear layer) or, for concrete subfloors, a moisture retardant product or moisture barrier adhesive that is approved as a concrete sealant for use in hardwood flooring installation.

Acceptable subfloor moisture testing methods include*:

• Calcium Chloride Test. The maximum moisture transfer must not exceed 3lbs/1000 square feet with this test.
• TRAMEX Concrete Moisture Encounter Meter. Moisture reading should not exceed 4.5 on the upper scale.
• Relative Humidity Probe Test. Maximum moisture reading is 75%.

*Please record and keep records of the following readings*

Concrete Subfloor Test Method Used*

•             Calcium Chloride (ASTM F1869)
•             RH (ASTM F2170-02) 1869
•             Electronic Meter (Tramex or equivalent)

Concrete Subfloor Moisture Reading*

•             % Moisture Content of Concrete Subfloor

A “DRY” SLAB, AS DEFINED BY THESE TESTS CAN STILL BECOME WET AT OTHER TIMES OF THE YEAR. THESE TESTS DO NOT GUARANTEE A DRY SLAB. ALL CONCRETE SLABS SHOULD HAVE A MINIMUM OF 6-MIL POLY FILM MOISTURE BARRIERS BETWEEN THE GROUND AND THE CONCRETE.

Wood Subfloor Moisture Content*

•             % Moisture Content of Wood Subfloor

Ambient Temperature Requirements

The jobsite should be evaluated for a consistent room temperature of 65°F- 85° F with relative humidity levels of 35%-55%. These levels must be maintained, before, during and after installation for the life of the installed hardwood flooring.

Flooring failures that are a consequence of not maintaining required ambient temperature levels, at all times, are not covered by the manufacturer warranty.

Once Your Flooring Arrives

Important steps must be taken prior to installation and is the responsibility of the Owner/User & Installer. These steps include, but are not limited to: product inspection and acceptance; proper handling and storage of the flooring/flooring cartons on-site; hardwood floor acclimation; individual plank inspection/selection and carton blending with aesthetic attention given to character, grade, color and milling variation, and with sufficient quantity on hand to complete the job.

ALSTON hardwood floors are a product of nature with naturally occurring imperfections in line with an industry accepted standard rate of approximately 5% of the total flooring purchased, including but not limited to, finish imperfections, grading and color variations, milling and general cutting waste. Individual planks may also be affected by die lot variations due to the staining process.

Product Inspection and Acceptance

It is the responsibility of the Owner/User & Installer to verify that the flooring delivered is what expected by the Owner/User before proceeding to installation. This can be accomplished by randomly inspecting boards from 2-3 different cartons.

• DO NOT PROCEED TO INSTALLATION if the flooring product is not what was expected by the Owner/User.
• Do not continue opening cartons and do not discard cartons that were opened during inspection. Immediately notify the ALSTON retailer where the flooring was purchased that there is a problem with your flooring delivery! Once any floorboards are installed, they are deemed as accepted by the User/Installer/Homeowner.
• During the installation process, the Owner/User & Installer should inspect and approve each piece that will be used in the flooring installation. The Installer must use reasonable selectivity and hold out or cut off pieces with defects that fall within manufacturing tolerance levels, whatever the cause.
• ALSTON INC. cannot honor claims due to a lack of on-site hardwood flooring inspection and acceptance by the Owner/User & Installer.
• ALSTON INC. will not accept responsibility for the installation of hardwood flooring with visible manufacturing defects.

Handling and Storage

Once ALSTON flooring is delivered to the jobsite, inspected and accepted by the Owner/User & Installer, the flooring cartons should be stored on a dry, flat surface with good air circulation in the area where it will be installed. Keep cartons closed. When moving or handling cartons care should be taken to prevent damage to the hardwood flooring inside.

Do not store cartons directly on concrete, in garages, basements, near outside walls or in areas where the temperature is uncontrolled. Damage caused by the improper storage and handling of the hardwood flooring product is not covered by the manufacturer warranty.

Acclimation Process

Wood flooring needs to reach a “moisture content equilibrium” with the surrounding environment where it will be installed. The process of reaching equilibrium is referred to as “acclimation”.  Proper acclimation ensures that the wood flooring has adjusted to the area where it will be installed before installation begins. ALSTON requires a minimum of 72 hours of onsite acclimation time before installation.

• Always store cartons on a flat, dry surface in the area where they will be installed.
• Do not open cartons until the day of installation and protect from moisture.
• Jobsite must have a consistent room temperature of 65°F- 85°F.
• Jobsite must have relative humidity levels of 35%-55% before, during and after installation.
• Wood Flooring Moisture Content must be within 4% of the subfloor before starting installation.

Flooring cartons must be placed in the area where they will be installed and allowed to acclimate for a minimum of 3 days. Do not open the flooring cartons or take out individual planks until acclimation has been achieved and the flooring is ready to be installed. Proper consistent temperature and humidity levels in the installation area are the keys to the acclimation process.

The required room temperature and humidity levels must be maintained for the life of the hardwood floor installation.

Once acclimation has been completed, the Installer should evaluate and record the moisture content of the hardwood flooring in relation to the subfloor.

Acclimation Moisture Readings*

•             % Moisture Content of Subfloor
•             % Moisture Content of Hardwood
•             % Difference between Subfloor & Hardwood

*The Installer/Owner should document that all pre-installation requirements have been met before proceeding to installation, including but not limited to, moisture testing and recording testing results using photos with location, date, time and initials of the Installer on each area of subfloor evaluated. The Owner should retain this documentation with this guide for future reference.

The National Wood Flooring Association (nwfa.org) provides a “Jobsite Checklist” to help with this task. (NWFA Installation Guidelines, Section IV, Appendix M)

Installation

INSTALLATION CONSTITUTES ACCEPTANCE of the hardwood flooring product and assures that all pre-installation requirements outlined here have been satisfied.  Installation is the responsibility of the Owner/User and Installer.  Only an experienced, licensed/certified hardwood floor installer should perform your ALSTON hardwood floor installation. NWFA Certified Hardwood flooring installers normally provide a period of warranty of their installation work. Installation related failures are not covered by the manufacturer warranty.

For best results, ALSTON recommends that its hardwood flooring is installed by a National Wood Flooring Association (NWFA) Certified Professional: (nwfa.org)

Preparing for Installation

For aesthetic purposes, hardwood flooring is often laid to the longest wall. However, the Owner/User, in consultation with the Installer should make the final decision which direction the planks will run before proceeding to installation.

ALSTON also recommends staggering plank end joints during installation to achieve an overall random appearance, but other patterns can be employed if so desired by the Owner/User and is the responsibility of the Installer.

IMPORTANT! The Installer should blend planks from different cartons to ensure an aesthetically pleasing color and shade mixture throughout the installation area.

Starting Installation

The tools generally needed for installation are: Handsaw or power saw, hammer, crowbar or pull bar, tape measure, pencil, chalk line, wood or plastic spacers, tapping block, carpenters square, adhesive trowel and a quality adhesive approved for hardwood flooring.

• Installation should begin next to an outside wall, as it is usually the straightest wall and used as a reference point in establishing a straight working line. A good way to establish a working line is to measure an equal distance from the wall at both ends and snapping a chalk line.
• Undercut or notch-out door casings to fit flooring thickness by placing a piece of flooring on the subfloor as a height guide for sawing.
• Remove door thresholds and base moldings and replace after flooring installation. Always leave at least 1/2" expansion space between flooring and all walls and vertical objects.
• Measure the distance from the wall at the width of the plank plus another 1/2" for an expansion space when establishing your working line. It is advisable to dry lay a few rows before proceeding installation to confirm your directional layout decision and working line. Adjustment of the working line may be necessary if the outside wall or other working line reference is out of square. This can be done by scribe cutting the first row of planks to match the wall, creating a straight working line.
• Installation of wood flooring over a raised foundation/crawl space will require a black 6 mil plastic membrane to cover the entire exposed dirt area under the crawl space and please ensure adequate crossed ventilation vents are not blocked.
• Please refer to “Special Instructions for Installations Over Radiant Heat Systems” for wood installation over radiant heat.

Installation Methods

Glue Down Installation

All required pre-installation testing and preparation must be completed before proceeding. If moisture problems were detected during the pre-installation phase, a moisture barrier or special adhesive with build-in moisture barrier should be utilized.

Acceptable Subfloors

• CDX Plywood
• OSB/Particleboard – Must be structurally sound.
• Concrete – With a minimum compressive strength of 3000 PSI

Adhesive Requirements

Only use ALSTON approved Urethane adhesive for hardwood flooring. The use of a cheaper flooring adhesive or other brands of glue not approved will lead to flooring failure and void the manufacturer warranty. Please follow the instructions for the hardwood flooring adhesive carefully.

• Allow for adequate cross ventilation when working with flooring adhesive.
• Allow proper set time before affixing the hardwood floor planks.
• Use the adhesive manufacturer recommended spreading trowel.
• Spread adhesive per the flooring adhesive instructions.

IMPORTANT! Only use 3M Orange Core Blue Tape for Delicate Surfaces. Other Adhesive/masking tape applied directly to hardwood floor surface may damage the factory finish and void the manufacturer warranty.

Starting Installation

1. Using the proper size/type trowel, held at a 45° angle, spread hardwood flooring adhesive as recommended by the adhesive manufacturer, starting at the outside wall.
2. Once adhesive has set, lay the first row of flooring with the groove facing the wall. Use a hammer and tapping block to tap against the tongue side to pull planks together. When near a wall, use a crow or pull bar to close end joints.
3. Never tap against the groove side or the end joints of the plank as doing so will damage the flooring finish and void the manufacturer warranty.
4. Use wood wedges at walls to maintain the required 1/2” expansion space from the hardwood flooring plank.
5. To ensure that plank end joints are not too close to each other in adjacent rows, it is best to rack out 3 to 4 rows as installation proceeds. Allow a minimum of 10” to 12” between end joints in adjacent rows.
6. When the first section is completed, continue by repeating the process, checking plank alignment with the working line, section by section until installation is complete.
7. Be careful not to shift the installed floor on the wet adhesive. If needed, weights can be used to hold flooring planks in place at the perimeter until the adhesive cures.
8. As each plank is laid, check for and remove excess flooring adhesive or spills immediately. Failure to remove excess flooring adhesive or spills from the flooring surface will damage the factory finish and void the manufacturer warranty.
9. When wiping up excess T&G glue or spills, use a dry or damp soft cloth. Do not use harsh adhesive-removing chemicals on the hardwood flooring surface as doing so will damage the finish and void the manufacturer warranty.
10. As installation proceeds, cut the last plank in each row allowing for the required 1/2” expansion space. Use a crow or pull bar to install the last plank ensuring a tight fit.
11. Leave the 1/2” expansion wedges in place until the flooring adhesive is fully dry.
12. Do not allow foot traffic for at least 8 hours and allow a minimum of 24 hours before heavy furniture is moved onto the hardwood flooring.

Finishing the Job

• Remove the 1/2” expansion spacers from the perimeter.
• Install or reinstall base and/or quarter round moldings to cover the expansion space.
• Install transition pieces such as reducer strips and T-moldings as needed.
• Clean and remove all dirt and debris from your new floor by dry dust mopping.
• Follow “Floor Care and Maintenance” instructions to ensure the longevity and lasting beauty of your new ALSTON Hardwood Floor.

IMPORTANT!  Adhesive/glue that comes in contact with the surface of the finished floors will damage the finish. The use of adhesive/glue removal products on finished floors, including but not limited to, acetone and paint thinner, could damage the finish. ALSTON INC. will not be liable for damages that are the result of a failure to prevent adhesive/glue exposure or the use adhesive/glue removal products.

It’s a good idea to save a few extra boxes of the materials in case of accidental damage. Planks can be replaced or repaired by a flooring professional.

Staple or Nail Installation

All required pre-installation testing and preparation must be completed before proceeding. If moisture problems were detected during the pre-installation phase, a moisture barrier should be in place.

Acceptable Subfloor Type

• A minimum of 5/8" CDX Plywood
• Staple or nail installation may be successful over existing vinyl, but not SPC products, provided:
• That the subfloor is properly attached to the joists and in good condition.
• That the subfloor is NOT particleboard or OSB or Particleboard.
• That the staple or nail penetration is not significantly lessened due to thickness of existing vinyl.

Underlayment Recommendation

• Felt paper
• Cork

IMPORTANT!

• Adjust and maintain correct air pressure for pneumatic nail gun so nails/staples do not break the Tongue on the flooring planks.
• The recommended length for the staple or nail is 1-1/2" with a spacing of 4" – 6" along the length of the plank and 2" from each end.
• Any plank damaged by the process of stapling or nailing, should be pulled up and replaced with a new plank before proceeding.
• Flooring damaged during the staple or nail installation process is not covered by the manufacturer warranty.
• Only use 3M Orange Core Blue Tape for Delicate Surfaces. Other Adhesive/masking tape applied directly to hardwood floor surface may damage the factory finish and void the manufacturer warranty.

Starting Installation

1. Use wood wedges at walls or obstructions to maintain the minimum required 1/2" expansion space from the hardwood flooring plank.
2. Staple or nail the first row of flooring with the groove facing the starting wall stapling or nailing in 4 to 6-inch spacing increments. Using a quality T&G glue product, glue the joint ends of each plank for added strength, and then, use a tapping block to ensure a tight bond between planks.
3. As each plank is stapled or nailed with a spacing of 4" – 6" along the length of the plank and 2" from each end, check for and remove excess T&G glue or spills immediately. Failure to remove excess T&G glue or spills from the flooring surface will damage the factory finish and void the manufacturer warranty.
4. To ensure that plank end joints are not too close to each other in adjacent rows, it is best to rack out 3 to 4 rows as installation proceeds. Allow a minimum of 10" to 12" between end joints in adjacent rows.
5. When the first section is completed, continue by repeating the process, checking plank alignment with the working line, section by section until installation is complete.

Special Instructions for Installations Over Radiant Heat Systems

All required pre-installation testing and preparation must be completed before proceeding. If moisture problems were detected during the pre-installation phase, an approved moisture barrier must be in place.

It is the Owner/User & Installer’s responsibility to ensure that the hydronic radiant heat system is installed and operating properly per the radiant heat manufacturer instructions.  Please make sure the  system is not on the same circuit for other floor covering types (that may allow higher temperatures) before proceeding to the hardwood floor installation.

Radiant Heat Systems must be designed and controlled specifically for hardwood flooring by the system manufacture, and include an outside temperature probe and thermostat, and also surface temperature controls.  Uses of a humidification system are required to maintain an in-door room temperature of 60°F -80°F and indoor relative humidity of 35% - 55% at ALL times to avoid excessive drying of the wood flooring.   In addition, the surface temperature of the floor should never exceed 82°F. Throughout the life of the floor, only 3 to 5 degrees daily increments can be used when adjust system temperature for either upward or lower adjustments.  Failure to do so will cause excessive heat damage and shrinkage in the hardwood flooring and void the manufacturer warranty.

Flooring failures due to improperly installed hydronic radiant heat systems are not covered by the ALSTON manufacturer warranty.

Approved ALSTON Hardwood Flooring over Radiant Heat

• Oak and Walnut products only

Approved Radiant Heat Type

• Hydronic radiant heat systems only

Installation Method

• Floating installation method with T&G glued only

Acceptable Subfloors

• CDX Plywood
• Concrete – With a minimum compressive strength of 3000 PSI

Underlayment Recommendation

• Cork
• Foam

Approved Hydronic Radiant Subfloor Systems

• Aluminum Hangers
• Channel Aluminum Board
• Sleeper Systems
• Lightweight Thermal Mass Concrete with min 3000 PSI compressive strength
• 1-1/8" T&G Warm board

Heating Control Requirements

Radiant heat installations must have a heat control system that helps maintain a constant baseline temperature and prevents overheating. Radiant heat surface temperatures that exceed 82 degrees will damage the hardwood flooring and void the manufacturer warranty.

ALSTON requires that an exterior probe and thermostat be installed and working at all times. Unlike conventional heating systems that switch on as needed, radiant systems work most effectively with hardwood flooring if the heating process is gradual with small, incremental increases in relation to outside temperature.

Radiant Heating System Acclimation Process

• Newly installed Radiant heated systems should be fully tested and running on a set temperature between 64°F – 72°F, for a minimum of 4 weeks prior to flooring delivery; acclimation and installation.
• Previously installed systems should be fully pressure tested, properly maintained, and set to room temperature (64°F – 72°F), for at least 7 days prior to flooring delivery; acclimation and installation.
• Use an incremental control strategy that brings the subfloor through temperature changes gradually. This incremental strategy should include the unit being turned on at least 3 days prior to installation at a temperature of 70 degrees; then, raised to 82 degrees for a period of 4 more days. The installation site should be aired out every day to allow excess humidity to exit the structure.
• Once the radiant heat acclimation process is complete and the flooring is ready to be installed, turn off the radiant heat system 24 hours prior to installation and remain off in the installation zone for the duration of the installation period
• Check wood sub floors to ensure the moisture content is less than 13% using an accurate wood moisture meter.
• The pH level of concrete subfloors should register between 6 and 9, on a 14 point pH scale.

Special Requirements – Under Floor Heat Sensors

As a condition of the product warranty, approved under floor heat sensors (available from ALSTON) MUST be installed under the flooring.  In the event of a claim, these under floor sensors will be used to determine whether excessive heat levels were applied to the floor. A minimum of ONE (1) under floor sensor per 200 sqft of flooring should be used for each job.  Place sensors directly onto subfloor surface prior to installing any vapor barrier or underlayment.  Spaced sensors evenly around the installation areas and near the electrical outlets for easy retrieval.   It is important that the sensors must be installed as follows:

1. Wrap each of the sensors in plain white paper. Make sure the white paper completely covers the sensors.
2. Fold a 48” length of duct tape in half lengthwise, enclosing the paper wrapped sensors at one end. Ensure duct tape completely encloses the sensors.  Make note of the sensor’s position in the duct tape strip.
3. Place duct tape strip with enclosed sensors directly on the subfloor. Sensors must be installed face down with number side facing the subfloor. Position duct tape strips so that they run perpendicular to the wall and sensor is approximately 45” out of the wall. Leave 2-3” of tape extending up the wall so it will be covered by the flooring & moldings and easy to retrieve.  To aid recovery, position strip so tabs are near electrical outlet.
4. Record the exact locations of installed sensors on a diagram. Keep this record in a safe place with product receipt and warranty registration form.  In the event of a claim, a copy of this diagram must be given to the manufacture.
5. Proceed with installation of flooring according to our floating installation instructions.

Preparing for Installation over Radiant Heat Systems

Radiant heating systems create a dry heat that can lower interior humidity levels. Use of a humidification system are required.  ALSTON recommends adding a separate humidifier to the HVAC system to ensure that environmental conditions are maintained with a temperature of 60°F -80°F and Relative Humidity of 35-55% at ALL times.

Installer should test the hydronic heating system and check that all radiant heat requirements have been met before proceeding to installation:

• Hydronic Radiant Heat System
• Engineered Oak Product
• Floating Installation Method
• Exterior Thermostat and Probe Installed
• Sensor Attached to Heating Unit
• Radiant Heat Acclimation Completed
• Separate HVAC Humidifier
• Radiant Heat System Working Properly
• ALSTON approved under-floor Heat Sensors, ONE (1) sensor per 200 sqft Installed

Starting Installation

1. Begin by laying the first row of flooring with the groove side facing the starting wall.
2. Use a hammer and tapping block to tap against the tongue side to pull planks together to ensure a tight fit. When near a wall, use a crow or pull bar to close end joints.
3. Never tap against the groove side or the end joints of the plank as doing so will damage the flooring finish and void the manufacturer warranty.
4. Use wood wedges at walls or obstructions to maintain the required 1/2" expansion space from the hardwood flooring plank.
5. To ensure that plank end joints are not too close to each other in adjacent rows, it is best to rack out 3 to 4 rows as installation proceeds. Allow a minimum of 10" to 12" between end joints in adjacent rows.
6. Apply continuous bleed of quality T&G glue in the top portion of the groove along the side and end joints of each plank to ensure a strong bond between them. Also apply small amount of T&G glue 4-6 apart on the exposed Tongue side of the plank.
7. As each plank is installed, check for and remove excess T&G glue or spills immediately. Failure to remove excess T&G glue or spills from the flooring surface will damage the flooring finish and void the manufacturer warranty.
8. Use 3M Orange Core Blue Tape for Delicate Surfaces to tape the boards in place until the T&G glue is dry.
9. When wiping up excess T&G glue or spills, use a dry or damp soft cloth. Do not use paint thinner or harsh adhesive-removing chemicals on the hardwood flooring surface as doing so will damage the finish and void the manufacturer warranty.
10. As installation proceeds, cut the last plank in each row allowing for the required 1/2" expansion space. Use a crow or pull bar to install the last plank ensuring a tight fit.

IMPORTANT!

• NEVER raise the wood flooring surface temperature setting above 82°
• Operate the radiant heating system at the lowest possible temperature required to achieve a comfortable living environment. A lower heat setting will also ensure a more even heating throughout the zone.
• Once installation is complete, turn the radiant heating system on immediately to achieve further acclimation of the flooring to the installation site. Avoid dramatic temperature changes by bringing the temperature up gradually in 3°F -5°F daily increments.
• Leave expansion space wedges in place for a minimum of 8 hours to allow the T&G glue to fully dry.
• Do not allow foot traffic for a minimum of 8 hours and allow a minimum of 24 hours before heavy furniture is moved onto the hardwood flooring.
• Only use 3M Orange Core Blue Tape for Delicate Surfaces. Other Adhesive/masking tape applied directly to hardwood floor surface may damage the factory finish and void the manufacturer warranty.

Finishing the Job

• Remove 3M Orange Core Blue Tape for Delicate Surfaces from the top of the boards.
• Remove the 1/2" expansion spacers from the perimeter.
• Install or reinstall base and/or quarter round moldings to cover the expansion space.
• Install transition pieces such as reducer strips and T-moldings as needed.
• Clean and remove all dirt and debris from your new floor by dry dust mopping.
• Follow “Floor Care and Maintenance” instructions to ensure the longevity and lasting beauty of your new ALSTON Hardwood Floor.

Protection During Construction or Remodeling

If your hardwood flooring is installed while other trades are working at the jobsite, or afterwards, when doing any kind of remodeling or wall painting, it should be completely covered by a clean, dry, plain uncoated cardboard or heavy bond paper product.

Before covering the hardwood flooring, it should be cleaned to remove grit, dust and other abrasive debris and thoroughly dry.

When covering the hardwood flooring area, the proper covering material should be overlapped 4 inches to the adjoining paper, secured with masking tape applied to the covering material only and then secured at perimeter walls or baseboards to prevent the covering from moving or shifting, and ensure that the tape itself, construction debris, dry wall dust and/or wet paint does not penetrate to the flooring below.

Do not use a wet cloth or wet mopping to remove drywall dust as doing so will create a pasty residue that will damage the factory finish and void the manufacturer warranty.

IMPORTANT! Do not cover ALSTON hardwood floors with plastic, red rosin, felt, wax paper or previously used cardboard. Damage to the factory finish caused by the use of improper floor covering materials will void the manufacturer warranty.

Adhesive/masking tape applied directly to hardwood floor surface will damage the factory finish and void the manufacturer warranty.

ALSTON hardwood floors are durable and easy to maintain. The factory finish protects the wood and keeps the hardwood flooring looking beautiful with general and finish specific care and maintenance.

Preventive Floor Care

• Place high-quality floor mats or area rugs with a soft felt backing near entrances and high traffic areas to prevent loose dirt, debris and other abrasive substances from being tracked directly onto flooring surface. Do not use rubber backed mats as these will damage the factory finish and void the manufacturer warranty.
• Hardwood flooring that is installed in the kitchen should be protected in areas subject to cooking splatter, spills and water splashes. High quality throw rugs with a soft felt backing should be placed in front of the cooktop, oven, sink and dishwasher to protect the flooring finish.

IMPORTANT! Water spills, splashes, hot oil or food debris that lands on an unprotected area of the hardwood flooring must be cleaned up immediately! Damage to the factory finish from a failure to protect it from, including but not limited to, water spills, hot oil and food debris is not covered by the manufacturer warranty!

• Apply felt furniture pads to movable furniture, including but not limited to, chairs, tables, sofas and heavy furniture to protect the hardwood factory finish.
• Rearrange rugs and furniture periodically so the hardwood finish ages evenly. UV sunlight exposure may change the flooring color over time and is not considered a manufacturing defect.
• Keep pet nails trimmed and filed in order to minimize scratches and indentations. All hardwood floors will indent with enough force or when exposed to sharp objects.
• Maintain a consistent room temperature of 65°- 85° F with relative humidity levels of 35-55%, for the life of the installed hardwood flooring at all times.
• Only use hardwood cleaning products specifically formulated for your flooring product finish. Improper use of cleaning products will damage the factory finish.

IMPORTANT! Required room temperature and humidity levels must be maintained at all times, even when the home or building is not occupied.

• Do not walk on the hardwood floor with sharp “stiletto” style high-heel shoes.
• Do not use harsh cleaning products, including but not limited to, ammonia, acetone, alcohol, bleach, STP, abrasive cleaners or furniture cleaners on ALSTON hardwood floors.
• Do not use oil-based wax, oil soap, mineral oil, polish, or other household dusting products on ALSTON hardwood floors.
• Do not wet mop ALSTON hardwood floors as excess moisture will damage the finish and void the manufacturer warranty.
• Do not use a wet cloth to remove dry wall dust from the hardwood flooring as doing so will result in a pasty residue that will damage the flooring finish and void the manufacturer warranty.

Regular Care

• Dry dust mop or vacuum (raised beater or suction type) on a frequent basis to remove loose debris and dirt anywhere from the hardwood flooring surface.
• Use only hardwood floor cleaning products designed for hardwood floors.
• Do not use steam or steam cleaners or power scrubbing machines on the hardwood flooring.
• When the hardwood floor requires refinishing (acrylic or polyurethane) or re-oiling (oil finished floors) ALSTON recommends using the services of a NWFA Certified Professional. (nwfa.org)

Finish Specific Guidelines

UV Acrylic / Polyurethane Floor Care & Maintenance

ALSTON UV Acrylic and Polyurethane floors require the same general preventive, regular care and maintenance as our other hardwood finishes.

Regular Care

Daily cleaning to remove debris from the flooring surface should be done with a soft broom, vacuum cleaner (raised beater or suction type) or ALSTON Microfiber Mop Set.

Use floor cleaning products especially made for Acrylic or Polyurethane finished floors such as Bona Hardwood Floor Cleaner.

First, dry mop the floor to remove all dirt and debris, then follow the instructions on the cleaning product insuring that you do not over saturate the floor.

Avoid using water and vinegar, soap-based cleaners, or wax on your hardwood floor as they can dull or leave a film on the finish over time.

Recoat/Refinish

When the hardwood floor requires a recoat or refinishing, ALSTON Floors, Inc. recommends using the services of an NWFA Certified Professional. (nwfa.org)

Oil Finish Floor Care & Maintenance

ALSTON oil finished floors provide a more natural looking matte finish that is durable and easy to maintain. Oil finished hardwood floors require the same general preventive, regular care and maintenance as our other hardwood finishes.

Oil finished floors installed in high traffic or commercial areas will require more frequent maintenance including periodic deeper cleaning and rejuvenation.

Regular Care

Daily cleaning to remove debris from the flooring surface should be done with a soft broom, vacuum cleaner (raised beater or suction type) or ALSTON Microfiber Mop Set.

Use ALSTON Wash & Care Floor Cleaner spray along with the Microfiber Mop Set to clean areas that have become soiled. Spray a small amount of cleaner on a soft dry cloth, then wipe to remove marks and dirt. This cleaner will not leave streaks or a film and can be used as often as desired.

IMPORTANT! Do not use products containing alcohol on ALSTON oil finish hardwood flooring. Most general cleaning products contain alcohol as a drying agent and by its chemical nature will damage the factory oil finish and void the manufacturer warranty.

Oil Finish Touch-up

Over time, the hardwood floor oil finish may need treatment with ALSTON Touch-Up Oil. There is no set time when you will need to do this kind of touch-up. Areas of your oil finished floors that experience heavier traffic than others may require touch-up sooner, while other areas may not need it until much later.

Heavy Duty Cleaning and Rejuvenation

High traffic or commercial flooring areas that become heavily soiled require deeper cleaning and oil finish rejuvenation periodically. ALSTON’s Spot Remover & Rejuvenating Oil should be used for this purpose.

Remove loose debris and clean with ALSTON’s Wash & Floor Cleaner spray.

Apply a small amount of ALSTON’s Spot Remover & Rejuvenating Oil to a soft cloth or scotch pad and gently rub to remove dirt from the flooring surface.

Remove excess oil with a moist (not wet) microfiber cloth or the sponge side of the scotch pad. Repeat this procedure for all flooring areas that require rejuvenation.

Do’s & Don’ts for Oil Finish Floors

• Clean up spills, hot oil/cooking splatter or other moisture immediately.
• Maintain a consistent room temperature of 65°- 85° F with relative humidity levels of 35-55%, for the life of the hardwood flooring at all times.
• Do not use harsh cleaning products, including but not limited to, ammonia, acetone, alcohol, paint thinner, bleach, STP, abrasive cleaners or furniture cleaners on ALSTON oil finish hardwood floors.
• Do not use oil-based wax, oil soap, mineral oil, polish or other household cleaners or dusting products on oil finished hardwood floors.
• Do not allow cosmetic lotions or other oil based products to come in contact with the oil finish.
• Do not wet mop oil finish hardwood floors as excess moisture will damage the finish and void the manufacturer warranty.
• Do not use a wet cloth to remove dry wall dust from the oil finish hardwood flooring as doing so will result in a pasty residue that will damage the flooring finish and void the manufacturer warranty.
• Do not use Acrylic or Polyurethane wood cleaning products on ALSTON oil finish flooring as doing so will damage the factory finish and void the manufacturer warranty.
• Only use hardwood floor cleaning products specifically formulated for oil finish hardwood flooring. The use of cleaning products not intended for oil finish hardwood flooring will damage the factory finish and void the manufacturer warranty!

IMPORTANT! Adhesive glue or tape that is used or left on the surface of an oil finished floor will damage the factory finish and void the manufacturer warranty. The use of any adhesive glue or tape removal product to remove adhesive glue or tape residue left on the surface of an oil finished floor, including but not limited to, acetone and paint thinner, will damage the factory finish and void the manufacturer warranty. Alston Inc. will not be liable for damage caused by the use of adhesive glue or tape on its oil finish hardwood flooring, and/or adhesive glue or tape removing products used to remove their residue.
