Prelude is an acrylic floor preparation solution designed to improve flooring substrates before the application of floor-covering adhesives. Prelude will improve dry, porous substrates for a better bonding surface, help protect the adhesive from alkalinity damage and improve adhesive spread rate. Prelude is suitable for use over APA approved flooring grade plywood, concrete or acoustical concrete and floor patch and can prevent over absorption of adhesives resulting in a better bond. Prelude may also be used as a primer for gypsum-based substrates prepared in accordance with ASTM F2419.
