Bostiks Wood P105 PRO is an easy-to-trowel urethane adhesive to adhere all engineered, acrylic impregnated, solid plank, shorts, bamboo and parquet hardwood flooring designed and recommended in writing by the hardwood flooring manufacturer for glue-down applications. It provides a flexible and tenacious bond to a variety of surfaces. Bostik Wood P105 PROs elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor. WOOD P105 PRO may be used on concrete slabs with moisture vapor emission rates (MVER) up to 5 lbs. per 1,000 square feet per 24 hours (using an anhydrous calcium chloride test kit according to ASTM F-1869 test method), and up to 80% relative humidity (RH) (tested in accordance with ASTM F-2170). For substrates that are greater than 5 lbs. MVER or 80% RH, use Bostiks Roll-Cote or MVP4 prior to the application of WOOD P105 PRO or use a Bostik all-in-one adhesive for unlimited moisture vapor protection. Bostiks Wood P105 PRO exhibits a long open time making installation easier and faster. This adhesive has low VOCs and does NOT contain any water.
