CERESIT® CT 7 is used in preparation for priming absorbent substrates such as: concrete, traditional cement plasters and cement-lime, cellular concrete. The use of CT 7 is especially recommended for gypsum and aerated concrete substrates. CT 7 can be used inside and outside buildings, among others before fixing ceramic tiles, filling, applying putty, painting, wallpapering or fixing thermal insulation boards. Available pack size: 1 l and 5 l.
Substrates primed with CERESIT CT 7 must be dry, load-bearing and free from substances that reduce adhesion: fats, bitumen, dusts, etc. Dirt and weak layers must be removed. This also applies to existing adhesive paints that need to be scraped off and wash off with water.
Shake the content of the CERESIT CT 7 package several times. Gypsum substrates and strong paint coats are necessary to sand with coarse sandpaper and thoroughly clean and remove dust. In places of algae growth and mould decomposition, a fungicide should be used.
Apply the prepared CERESIT CT 7 Universal primer onto the substrate with a brush or roller. CT 7 dries in approx. 2 hours. If the substrate is still absorbent after drying, then the priming operation should be repeated. Wash tools and fresh splashes with water.
CERESIT CT 7 is a Universal primer for priming substrates before: fixing ceramic tiles and slabs, thermal insulation, painting, wallpapering, speckling. CT 7 improves significantly substrate adhesion, it is fast drying and eco-friendly.
CERESIT CT 7 is a preparation for priming absorbent, absorbent substrates such as: concrete, traditional cement plasters and cement-lime, cellular concrete. The use of CT 7 is especially recommended for gypsum and aerated concrete substrates. Also suitable for priming non-impregnated plasterboards.
Work should be carried out at ambient and substrate temperature from +5°C to +25°C and at air humidity below 80%.
