How to use

SUBSTRATE PREPARATION FOR APPLICATION OF CERESIT CL 69

The substrate must be solid, dry, clean and free of substances that may impair adhesion. A few isolated cracks in the screed do not cause a problem as long as the crack edges are level. Before applying the CL 69 membrane, pipe penetrations as well as wall and floor connections (gullies etc.) should be waterproofed with the pre-fabricated CERESIT system components.

APPLICATION OF CERESIT CL 69

Place the CERESIT CL 69 membrane on the floor and cut it to size using a cutting knife and scissors. Comb a certified CERESIT tile adhesive onto the prepared substrate using a notched trowel (notch size 4 mm). Place the membrane into the adhesive bed within the open time of the adhesive.
