USE TO INSTALL:
Cork: Use to install natural cork underlayments to approved substrates.
Sheet Goods: Commercial, felt-back and inlaid sheet vinyl.
Carpet: Jute, latex unitary, polypropylene (actionbac®), needle punched, polyurethane laminate, attached polyurethane cushion, woven carpet, rubber foam back, all backings designed for the installation of direct glue down carpet, and Shaw approved double-stick installations. *NOTE - Not recommended for use with vinyl back flooring of any kind, LVT/LVP or Shaw broadloom carpet.
USE OVER: Concrete: above, on or below grade in the absence of excessive moisture and alkali. APA registered plywood underlayment, hardboard, association grade particleboard. NOT recommended over existing vinyl flooring.
FLOOR PREPARATION: Floor must be clean, level and dry. Remove all foreign substances such as wax, grease, dirt and any substance or chemical that would interfere with a good bond. Test concrete subfloor for alkalinity (pH of floor should be between 5 and 9). Take corrective measures if concrete surface pH is outside these limits.
Moisture tests should be performed using an anhydrous calcium chloride test according to ASTM F-1869 test method. Moisture emissions should not exceed 5.0 lbs. per 1000 square feet per 24 hours (2.27 kg/92.9m2/24 hours).
Relative Humidity readings according to ASTM F-2170 should not exceed (RH) 85%. If both tests are performed the RH test is the qualifying standard. Fill all holes and cracks with a Portland cement based patching compound. Sand high spots, install underlayment grade plywood or particleboard underlayment over tongue and groove flooring to eliminate the possibility of telegraphing.
For best results, the room, floor covering and adhesive should be between 65°F (18°C) and 95o F (35o C) and at a relative humidity between 30% and 60% for 24 hours before, during and after the installation.
