Rockcote Solprime is a high performance, solvent based, acrylic primer for hard and dense substrates such as steel trowelled, precast and tilt-up concrete. It is also recommended for difficult masonry surfaces and is designed to promote adhesion and eliminate excessive substrate absorption. Rockcote Solprime provides an alkali resistant barrier which will extend the life and improve the performance of subsequent applications of acrylic based paints and textured finishes.
