Primer for absorbent substrates R 777 10l CERESIT

CERESIT R 777 is a highly effective dispersion primer, specially developed for the treatment of absorbent substrates before applying leveling compounds or directly gluing floor coverings. Thanks to its properties to agglomerate residual dust and seal pores in screeds and concrete, it provides a strong and stable base for subsequent construction activities.

The primer serves as a strong bonding bridge between the substrate and CERESIT adhesives or self-leveling screeds, improving adhesion and reducing the risk of delamination. With extremely high coverage and easy application, R 777 is an indispensable choice for professional flooring solutions.
