Why to use primer Ceresit CT 17?
Unbonded dust is separating agent which can dramatically lower adhesion of next layer leading to a crack formation and debonding of material. Dust must be vacuumed and its rest will be successfully bonded to substrate due to the primer performance, making adhesion surface suitable for next steps.
Special primer formulation ensure efficient penetration in depth of the substrate structure and close the capillary pores, thus strengthening surface of the substrate.
REDUCES WATER ABSORPTION
Using primers we reduce water uptake from subsequent layer and thanks to that we have following benefi ts: uniform adhesion on any fragment of the substrate; subsequent materials dry in the same conditions; easier application of next layers e.g. adhesive, skim coat etc… reduced risk of too fast drying of subsequent layers thus less cracks or delamination; economic use of subsequent materials e.g. adhesive, plaster, skim coat etc…

Highly absorbent substrates must be primed at least 2 times to prevent micro-cracks.
