CERESIT® CM 77 is an ultra flexible ready-to-use tile adhesive suitable for indoor and outdoor use that ensures a reliable and firm bond even on the most difficult substrates like metal, wood, glass, synthetic resins and coatings - usually without a primer. With sound-dampening properties. Perfectly suited for the most challenging applications, such as large tiles and slabs outdoors. Available pack size: 8kg
CERESIT CM 77 adheres to all clean, solid, load-bearing, even, dry and moist substrates, which are free from substances which can reduce adhesion. Uneven areas or depressions should be levelled before (see CERESIT Flooring and Interior Finishes products). Coatings of insufficient load-bearing strength must be removed.
The adhesive should be applied with a suitable notched trowel, depending on the respective tile size. For indoor use, the mortar coverage (contact area) at the back of the tile must be at least 65 %. For outdoor use, a minimum mortar coverage of 90 % is required.
CERESIT CM 77 is a silane-based adhesive and cures by contact with moisture (air humidity). To fasten the hardening process the adhesive layer should be sprayed with a thin water film. Attention! Tools and tile surfaces cannot be cleaned with water - pre-clean the tools and surfaces with a dry cloth. Fresh adhesive residues can be removed with alcohol, oil or paint thinner; hardened material can only mechanically be removed.
Suitable for ceramic tiles and slabs, marble, artificial stones (agglomerated stones), natural stone slabs, clinker, porcelain, glass tiles and glass mosaic etc.
CERESIT CM 77 can be used for installing tiles and slabs on heated or cooled floor constructions.
Use CERESIT CM 77 only in dry conditions and at temperatures of +5 °C to +35 °C. The optimum ambient and material temperature is 23 °C and 50 % relative humidity. At low temperatures, we recommended bringing the adhesive up to temperature before application.
