Schluter®-PRIMER-U is a ready-to-use universal primer used to enhance adhesion of mortars for hard-to-bond substrates such as gypsum underlayment, existing tile, terrazzo, steel (e.g. raised access panels), flooring adhesive residue, concrete with curing compounds, latex paint, and glass tile.
Schluter®-PRIMER-U is a ready-to-use, one-component, solvent-free, 100% acrylic, water-based primer. It is used to ensure excellent adhesion when applying Schluter thin-set mortars to difficult-to-bond-to surfaces such as gypsum underlayment, raised access panels, and existing tile. PRIMER-U is suitable for use with Schluter SET®, Schluter ALL-SET®, and Schluter FAST-SET® in interior applications where increased adhesion is required over various porous and non-porous substrates.
PRIMER-U is a translucent orange liquid that dries to a slightly glossy film approximately 15-60 minutes after application. PRIMER-U provides a strong bond to gypsum underlayment, concrete, existing tile, glass, plywood and OSB subfloor panels, terrazzo, steel, VCT flooring, well-bonded flooring adhesive residue, and latex paint.
