CERESIT CT-17 PROFI DEEP-PENETRATING PRIMER 1 L

Ceresit CT 17 PROFI Deep-Penetrating Primer is a product designed to strengthen the surface of all absorbent substrates. The product is intended for priming both interior and exterior surfaces of buildings (walls, floors, ceilings) where ceramic tiles, thermal insulation, or flooring materials will later be installed, where leveling layers will be poured, or where surfaces will be wallpapered, spackled, or painted. The primer is solvent-free. Substrates primed with CT 17 PROFI (all types of plaster, concrete, poured cement, heated floor sublayers) have lower absorbency, which prevents the tile adhesives, intermediate layers, skim coats, or paint layers applied later from drying too quickly. The product penetrates deeply into the substrate and binds the aggregate particles together; however, it does not increase the strength properties across the entire substrate. CT 17 PROFI is particularly recommended for use on gypsum, anhydrite cement, and aerated concrete surfaces. It is also suitable for priming wood-based panels and non-impregnated gypsum boards. The product causes the substrate to take on a yellowish tint.
