Schluter; KERDI-COLL is a two part sealant adhesive from the Schluter; brand. The adhesive is based on a solvent free acrylate dispersion and a reactive cementitious powder. Mix the two parts together prior to application to activate the adhesive.

KERDI-COLL is suitable for adhering and sealing over laps of KERDI membranes. In addition, KERDI-COLL can be used to tightly adhere the KEBA on KERDI sealing tape and DITRA matting. This construction, in conjunction with the materials KERDI or DITRA and the corresponding sealing band KEBA, results in a waterproofing assembly that meets the stringent requirements of moisture categories 0-B0 of the German ZDB Information Sheet. Coverage for fixing KERDI KEBA tape to DITRA matting is 12 linear metres per container, or 25 linear metres for KERDI matting. When fixing KEBA Tape to DITRA-HEAT Matting the coverage is 7 linear metres.

This adhesive is hard wearing and suitable for both wall and floor areas, in both indoor and outdoor applications! (except with Schluter KERDI-BOARD). Schluter; KERDI-COLL should always be applied to dry cuts/membranes for maximum adhesion. The curing and installation time is approximately 60 to 90 minutes at 20 to 30 degrees. The higher the temperature, the quicker the adhesive will set and the less working time you will have. The ambient temperature for installation shouldn’t fall beneath 5 degree until the product has cured completely.

As an authorised national distributor for the Schluter range, we are confident that we can offer the best advice and prices. Our fully trained staff can get technical information, manufacturer support and also, the best possible prices for the complete range including DITRA matting.
