How is sealing slurry applied?

Apply sealing slurry
The ready-to-use mixture from the hardware store is mixed according to the manufacturer's instructions. Stir the mixture until a lump-free mass, the so-called sludge, has formed.
You can apply the slurry with a brush, with a roller or spatula or even spray it on. Work on the walls first, then the floor. The transitions in corners and between wall and floor are to be smoothed out with a fillet.
The thickness of the order is only a few, up to a maximum of 5 millimeters. It is usually applied in two layers after the first layer has dried. For optimal curing, make sure that the sealing slurry is not exposed to direct sun, drafts, rain or frost.
