The substrates must be clean, crack free, sound, dry, and free of substances that would impair adhesion.
Lift the top container slightly to allow the hardener to drain completely into the canister below. Then carefully mix resin and hardener using a hand drill with stirring attachment for at least 2 minutes. If available, use a continuously adjustable stirrer.
Apply a generous coat of CERESIT R 755 with a lamb- skin roller. For blocking the capillary rise of moisture or residual moisture in concrete floors or cement screeds, a second coat must be applied crosswise not later than 48 hours after the first coat has dried.
