For the Interior Installation of:
- Polypropylene (Actionbac®), woven, hot melt, latex unitary, needle-punch, urethane foam (Enhancer™), polyurethane laminate (Lifespan®), sponge-rubber, jute, and latex foam, commercial carpet pads and felt-back sheet vinyl.
For Use Over:
- APA underlayment grade plywood sanded oriented strand board (OSB), hardboard, poured in place gypsum underlayment (primed) and terrazzo.
- Do not use vinyl-backed products.
- Product Notes
- Concrete moisture levels must not exceed 5 lbs./1,000 sq.ft./24 hrs. (ASTM F1869) or 85% RH (ASTM 2170).
- Always check with the flooring and cushion manufacturer for their allowable moisture limits.
- Do not exceed the manufacturer’s recommendations.
- Check with the flooring manufacturer for the recommended substrates for their products.
- The trowel notches referenced are those typically recommended for the type of flooring being installed.
- Consult flooring manufacturers for their specific trowel recommendations.
- Surface conditions and type of flooring will ultimately determine trowel notch size and coverage.
- After installation, restrict foot traffic and moving of heavy objects for 24 to 48 hours.
- Preparation
- Ensure substrate, flooring material and adhesive are acclimated 48 hours before installation and installed at the same temperature and relative humidity (RH) expected during normal use (between 65 - 95 ºF, ≤65% RH).
- Refer to the flooring manufacturer’s specific recommendations.
- Ensure adequate ventilation during installation.
- Subfloors must be structurally sound, dry, smooth, flat and free of excess moisture/ alkali (≤9) and all substances that might interfere with bonding.
- Ensure proper ventilation and moisture protection under all wood subfloors.
- Repair cracks, holes, high spots and irregularities.
- Use polymer-modified, cement-based patching compounds.
- Expansion/moving joints must not be filled/covered with flooring.
- Installation
- Spread adhesive uniformly with an appropriate trowel.
- Adhesive ridges should be of sufficient height to achieve full coverage of the substrate and the deepest recesses in the back of the flooring material.
- Place flooring into the adhesive while the adhesive is still fresh.
- The amount of time in which you have to place the flooring will vary with temperature and humidity.
- The higher the temperature and the lower the humidity the faster the adhesive will set.
- Lift flooring periodically to ensure 100% transfer to the substrate and the deepest recesses in the backing of the flooring material.
- Clean Up & Removal
- Fresh Adhesive: Warm soapy water.
- Dry Adhesive: Capitol CL800 adhesive cleaner or mineral spirits sparingly with a clean, white cotton cloth.
- Do not pour cleaner directly onto the flooring.

Safety & Health
- Warnings
Existing Flooring and Adhesives May Contain Asbestos:
- Unless you have confirmation that the existing flooring system is not asbestos-containing, do not sand, dry sweep, dry scrape, abrade, drill, saw, bead blast, mechanically chip or pulverize existing flooring or adhesive without taking all appropriate precautions.
- Refer to local, state and federal guidelines for treatment and removal of these products. You may also refer to the Resilient Floor Covering Institute’s “Recommended Work Practices for Removal of Resilient Floor Coverings.”
Existing Paint May Contain Lead:
- Unless you have confirmation that the existing paint is not lead-containing, do not sand, dry sweep, dry scrape, abrade, drill, saw, bead blast, mechanically chip or pulverize existing paint without taking all appropriate precautions.
- Refer to local, state and federal guidelines for treatment and removal of lead containing paint.
