How to use

SUBSTRATE PREPARATION FOR APPLICATION OF CERESIT CM 25

CERESIT CM 25 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. Coatings of insufficient load-bearing strength must be removed. Gypsum/anhydrite or paint coats (not chalking, good adhesion) must be mechanically roughened and freed from dust.

MIXING OF CERESIT CM 25

Pour the content of the packaging into the measured amount of clean, cool water and mix it with a drill mixer until a homogenous mass without lumps is obtained. It is necessary to wait for 5 minutes (maturing time) and then mix it once again. If necessary, carefully add water until the desired consistency is achieved.

APPLICATION OF CERESIT CM 25

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 (combined laying method should be used i.e. additionally apply a thin layer of the mortar on the tile backside). CERESIT CM 25 is fast setting - keep in mind the shortened skin formation time and pot life compared to normal setting tile adhesive.
