CERESIT® CM 17 is a super flexible tile adhesive with Fibre-force technology ideal on critical substrates and for installing large format tiles. CM 17 can be applied in indoor and outdoor areas and is perfect for wet areas and swimming pools. Adheres to all solid, load bearing, clean and dry substrates that are free of substances that reduce adhesion (grease, dirt and dust). CM 17 is highly deformable tile adhesive with high bond strength.Available pack size: 5 kg, 25 kg, 27,5 kg.
Prepare the substrate and make sure it is not wet. Cement and concrete screeds must be fully cured prior application of CERESIT CM 17. Any existing dirt, loose debris and coatings shall be mechanically removed. Absorbent substrates shall be primed and left to dry. Surface unevenness up to 5 mm can be filled on the previous day with CM 17.
Mix CERESIT CM 17 (25kg) with 5.75L to 6.25L of clean water using a slow speed drill until a homogenous mass without lumps is achieved. Leave for 2 minutes and then mix again.
Apply CERESIT CM 17 Super flex tile adhesive with a suitable notched trowel on the substrate. For indoor use, the tile adhesive should cover at least 65% of the tiles backside. For outdoor use, the back-buttering method should be followed to cover at least 90% of the tiles backside. Place the tiles only during the open time of the CM 17 adhesive.
CERESIT CM 17 is recommended to be applied in indoor and outdoor areas and for tile-on-tile application, balancing substrate deformations on critical surfaces like balconies, terraces, etc., for difficult substrates like heated floors and large size tiles.
CERESIT CM 17 provides a flexible adhesive bed, prevents shear stresses, and is used for indoor and outdoor applications, on: walls, floors, dry substrates and calcium sulphate screeds; balconies, terraces and facades; difficult and critical substrates such as pre-existing tiles, gypsum, plasterboards, fibre-reinforced plasterboards, and other substrates subjected to tiny movement.
The application of CERESIT CM 17 should be carried out in dry conditions at an air surface temperature ranging between +5°C to +40°C.
