(2.3-2.8 m2/3.78 L)- Suitable Substrates and Substrates Preparation
- Suitable Substrates
- When properly prepared, suitable substrates include:
- Concrete slabs
- Cured leveling compounds
- OSB (underlayment grade)
- Radiant heated subfloors
- Plywood (underlayment grade)
- Ceramic tile
- Terrazzo
- Cement backer board
Substrate Preparation
- The subfloor must be checked according to NWFA guidelines. Ensure that the subfloor is structurally sound, cured, smooth, dry, clean and free from dust, dirt, grease, paint, old adhesive, curing agents, sealers, cutback** any other contaminants that could interfere with a good adhesive bond.
- Concrete Slab: Must be cured at least 28 days. Do not use in areas subject to hydrostatic pressure or with pre-existing moisture conditions. pH should be between 7-10. The subfloor must be dry to the touch and not visibly damp. Slab must be prepared to receive flooring in compliance with ASTM F710 and NWFA guidelines. Slabs over a year old with high moisture readings indicate a moisture problem related to hydrostatic pressure, broken water pipes, or improper maintenance.
- Terrazzo: Surface should be sanded so that all polishes and glaze compounds are stripped. After sanding, thoroughly vacuum and clean the substrate with mineral spirits and allow to dry before installing the wood flooring. APA approved Plywood and OSB Type Subfloors: Panels must be securely fastened. Eliminate movement with screws. Sand all high joints. Fill and patch low areas. Refer to flooring manufacturer for guidelines of moisture content difference between properly acclimated wood flooring and subfloor materials.
- Radiant Heated Subfloors: Check flooring manufacture’s specifications to determine if the flooring is approved over radiant heated subfloors. WoodEndure™ is approved for use on hydronic system radiant heated subfloors, provided the system is fully embedded in concrete. Lightweight toppings must be primed first. Turn off the
- heat 48 hours prior to the installation and leave the heat off until 48 hours after the installation is completed.
**Cutback Adhesive Residue (non-asbestos) – Application over asphalt-based cutback adhesive residue is acceptable provided the residue is well bonded. Subfloor preparation of the existing cutback adhesive requires only that the ridges or high spots be knocked off, typically with 1-3 passes of a mechanical scraper. NOTE: Mechanical removal of cutback by sanding, grinding or blasting can be hazardous since old cutback adhesive may contain asbestos. Harmful dust may result. Inhalation of asbestos dust may cause asbestosis or other serious bodily harm. Consult all applicable government agencies for rules and regulations concerning the removal of floorings and adhesives that contain asbestos. Tacky or pressure-sensitive adhesive must be mechanically removed by a method such as shot blasting.
- Limitations Information
- Interior use only
- Do not use on wet, dusty or contaminated substrates
- Subfloor must be dry
- Do not use in areas subject to hydrostatic pressure
- Room temperature should be between 65ºF (18ºC) and 90ºF (35ºC) during application
- Installation Instructions
Application
Installing Wood Flooring with no pre-installation moisture testing:
- Subfloor must be flat [3/16" (4.8 mm) in 10' (3 m) radius or 1/8" (3.2 mm) in 6' (1.8 m) radius].
- Follow all manufacturer’s instructions and guidelines
- Use a 1/4" x 1/4" (6.4 mm x 6.4 mm) V-Notch trowel.
- Trowel the adhesive parallel to wood flooring in 2'-3' (.6-.9 m) sections and place wood immediately into adhesive. Spread adhesive beyond where the last row of flooring stops to ensure there are no voids between stopping and starting points. 100% adhesive coverage is required for moisture protection.
- Repeat steps 3-4.
- Trowels will wear down over time and must be changed to achieve correct coverage.
Glue down only application:
- Subfloor must be flat [3/16" (4.8 mm) in 10' (3 m) radius or 1/8" (3.2 mm) in 6' (1.8 m) radius]. Concrete moisture testing must be performed according to ASTM F1869 with levels not to exceed 3lbs/1000ft2/24 hrs (1.3kg/93m2/24hrs) and/or ASTM F2170 with levels not to exceed 75% RH. Subfloor moisture levels must not exceed wood flooring manufacturers guidelines. If it exceeds any of these, use the moisture control method.
- Follow all manufacturer’s instructions and guidelines.
- Reference trowel selection for correct trowel for your application.
- Do not spread more adhesive than can be covered within 30-45 minutes.
- Periodically check to ensure there is 90% adhesive transfer to the board.
- Trowels should be changed regularly.
Clean-up
- Remove the adhesive from the wood floor surface as soon as possible before the adhesive dries. Use a soft cloth and Mineral Spirits carefully to not harm the finish.
