Ceresit CT 17 Primer - Invisible Power

REASONS FOR USING CT 17

BINDS DUST

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.

PENETRATES DEEPLY

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 uniform adhesion on any fragment of the substrate, subsequent materials dry in the same conditions, easier application of next layers, economic use of subsequent materials and reduced risk of too fast drying of subsequent layers thus less cracks or delamination.

CT 17 IN ACTION

Fields of Application

CT 17 can be applied before:

• Tiling

• Self-Levelling Compounds

• Façade Thermal Insulation

• Skim Coats

• Rendering Mortars

• Paints

HOW TO USE IT?

Shake the primer

Wait 2 hours until it fully dries

Apply in onto the substrate with a brush 

If you are fixing ceramic tiles on cement or cement lime substrate, you can continue 15 minutes just after priming

CT 17 PROFI - Deep penetrating, fast drying primer

Formulation for surface strengthening of all absorbent substrates

Properties

  • for all absorbent substrates
  • strengthens the substrate surface
  • reduces substrate absorbency
  • improves adhesion to the substrate
  • application of tiles on cement and cement-lime substrates after only 15 minutes
  • yellow colour — allows to control work phases
  • vapour permeable
  • very low emission EC1
  • facilitates application of subsequent layers of, e.g., adhesives, fillers, putties, floors

Description:

Ceresit CT 17 Profi is designed for priming substrates (walls, floors, ceilings) inside and outside buildings prior to fixing ceramic tiles, pouring floors, fixing floor lining, papering, puttying, painting, or fixing thermal insulation boards. The primer is solvent-free. Substrates primed with Ceresit CT 17 Profi (all kinds of plaster, concrete, screeds, primers with underfloor heating installations) are of lower absorbency, which prevents too rapid overdrying of adhesive mortars, flooring, putties and paints.
