New from MAPEI, ECO Prim Grip is a ready-to-use, bond-promoting primer that prepares an existing tile or stone surface to receive a new installation without the time, labor or dust of scarification, the company said. ECO Prim Grip enhances the performance of mortars and their adhesion to existing ceramics and other difficult substrates, and can be applied with a roller in only one coat. www.mapei.com
