Step by Step

Substrate preparation

CM 9 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). Before applying CM 9 tile adhesive, check the residual moisture of the substrate! Absorbent substrates should be primed with Polybit primer. Please refer to the Technical Data sheet!


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 2 minutes (maturing time) and then mix it once again. If necessary, carefully add water until the desired consistency is achieved.


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 %. Fresh excess mortar can be removed with water; hardened material can only mechanically be removed. Use CM 9 only in dry conditions and at temperatures of +5 °C to +40 °C.
