Substrate preparation
CT 32 adheres to all solid, load-bearing, clean, dry and moist substrates free of substances which may impair adhesion. The surface must have a rough, open-pored structure. Pre-wet concrete, cement screed, cement plaster and brickwork so that they are no longer absorbent.
Application
Sprinkle CT 32 into clean, clear water and stir until completely free of lumps. Observe the following mixing ratio: 1 part by volume of water to approx. 4 parts by volume of mortar or approx. 0.75 to 0.9 l of water for 5 kg of CT 32. Apply CT 32 within about 20 minutes and, if required, texture the surface. Protect the mortar against too rapid drying. CT 25 fine filler can be applied after only a few hours. Wait at least 5 days before applying paints and coatings.
