Applications & Uses
- Markets
- Application Method
- Application Instructions
- Refer to all manufacturer’s recommendations and approvals prior to Installation.
- For Indoor Use Only.
- Read Installation instructions and SDS thoroughly prior to installation.
- For best results install at 70°F (+/- 5°) and 50% R.H. (+/-5%).
- For proper trowel or roller selection please see Coverage section in this document.
- Spread adhesive using the recommended trowel or roller.
- PSA Method (Porous and Non-Porous Substrates). Recommended for LVP/LVT.
- Allow spread adhesive to dry for 30-60 minutes or until adhesive is clear and does not transfer to fingertips when lightly touched.
- Install flooring within 12 hours. Protect open adhesive from dust and debris.
- Semi-Wet Set Method (Porous Substrates Only). Will result in a permanent installation and limited repositionability.
- Allow spread adhesive to partially dry for 10-15 minutes, then install flooring.
- Working time is approximately 20-30 minutes depending upon conditions.
- PSA Method (Porous and Non-Porous Substrates). Recommended for LVP/LVT.
- Within 1 hour of placing flooring into the adhesive you must roll and cross roll the floor with a 100 lb. three-section roller to assure adhesive has made proper contact with the flooring.
Clean-up: Remove wet adhesive immediately with a damp cloth. Use Mineral Spirits to remove dried adhesive.
- Approved Substrates
- Concrete
- Portland Based Underlayments
- Properly Prepared Gypsum
- APA Approved Plywood
- Terrazzo
- Fiber Cement Underlayment
- Radiant Heated Subfloors
- Properly Prepared VCT (Single Layer)
- Properly Prepared Sheet Vinyl (Single Layer, fully adhered)
Substrate Preparation: Follow flooring manufacturer's guidelines for allowable levels of concrete moisture content. Concrete substrate must be cured at least 28 days and prepared in accordance with ASTM F710. All concrete slabs must have an intact vapor barrier per ASTM E1745.Moisture tests are required on concrete subfloors. Moisture testing should be performed by ASTM F2170 In Situ Relative Humidity Test with readings not to exceed ninety-nine (99) percent or ASTM F1869 Calcium Chloride Test with MVER not to exceed twelve (12) lbs. per one thousand (1,000) square feet per twenty-four (24) hours. The maximum pH levels should not exceed a reading of 12.
- Limitations
- For Interior Installations only.
- Flooring must be acclimated per manufacturer's instructions.
- Do not install when the concrete RH is over 99%, per ASTM F2170.
- Do not install when MVER is over 12 lbs. per 1,000 ft² per 24 hours, per ASTM F1869.
- Although Flexera is a moisture tolerant adhesive, it does not form a moisture vapor barrier and will not protect flooring from moisture damage. Use of a moisture mitigation product such as TEC LiquiDam™ or LiquiDam EZ™ may be required for higher moisture content concrete.
- Do not install when the pH is greater than 12.
- Installll only when the substrate temperature is between 50º and 90ºF (10º-32ºC).
- Do not install into wet adhesive over nonporous substrates.
- Do not apply over adhesive residues.
- The dimensional stability of some vinyl flooring products is very sensitive to fluctuations in ambient environment conditions. H.B. Fuller Construction Products Inc. is not responsible for installation issues caused by dimensional changes in flooring.
- It is the sole responsibility of the installer to determine the suitability and compatibility of the adhesive for the user’s intended use.
