Strong bonding bridge

Ceresit R 777 is a dispersion water-based fluid primer, to be applied before the application of self-leveling compounds or repair mortars on absorbent or very absorbent concrete floors (porous), mortars, natural stone, ceramic tiles, etc.

Dispersion primer used as a bonding bridge for Ceresit levelling and smoothing compounds on absorbent substrates such as cement screeds and concrete floors, calcium sulfate screeds, levelling and smoothing compounds, dry construction boards. Can also be used before directly bonding floor coverings on suitable substrates with Ceresit adhesives.

Ceresit R 777 is not a moisture barrier. For indoor use only.
