SUBSTRATE PREPARATION FOR APPLICATION OF CERESIT CO 81

Before applying CERESIT CO 81, make sure the substrates are level, solid, load-bearing, clean, gypsum-free and free of substances which may impair adhesion. The surfaces to be sealed must be crack-free.

APPLICATION OF CERESIT CO 81 IN COMBINATION WITH CERESIT CR 65

CO 81 is either brushed or sprayed on. In the case of onlyslightly absorbent substrates, dilute CO 81 with water at aratio of 1 : 1. Immediately after the CO 81 coat was soakedup by the substrate, apply a slurry layer wet-on-wet. After theCR 65 layer is sufficiently hard, further slurry layers can beapplied. If CP 43, CP 44, CP 45 or BT 21 are to be used forsurface sealing, apply these products onto the second slurrylayer, after application of a priming coat (varies dependingon the product).
