SUBSTRATE PREPARATION FOR APPLICATION OF CERESIT CT 7

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.

MIXING OF CERESIT CT 7

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.
