Product specification

Product description

Properties

Regulates the porosity of the substrate 
Avoids air bubbles and coloration when placing floor leveling mortars 
Strengthens the surface cohesion of substrates and improves adhesion 
Ready to use 
Non-toxic, non-flammable

Consumption 

150 to 250 g/m² depending on the porosity of the substrate
Drying time : 1 to 4 hours depending on temperature and porosity of substrate
covering : after minimum 1 hour (weberprim tac must be dry)

Preparation of the substrate

substrates must be hard, clean, dry and not friable
scratch non-resistant substrates (peeling paint, concrete sludge, old adhesives of fitted carpets and vinyl coverings, plaster). Remove adhesive traces so that they form only a film. Only residual color on the surface may remain visible.
Always apply weberprim tac to gypsum substrates and polyconcrete (without curing) before installing the tiles with an
cement-based adhesive mortar. The gypsum substrates must be dry (< 1% residual moisture), dust-free and not polished. Scratch or
sand them, if necessary, to remove the polishing film
Cast anhydrite-based screeds should be sanded over the entire surface to remove the surface film.
