How to use

Surface Preparation

Ceresit CM 16 can be applied on even, load-bearing and compact substrates, free of any substances that reduce adherence (grease, dirt and dust).
Indoors and outdoors:
– Concrete (having residual moisture ≤2%)
– Cement screeds (without floor heating), plasters, cement and lime plasters (having residual moisture ≤1.5 %)
– Anhydrite substrates (without floor heating and having residual moisture <0.5%) and gypsum substrate (having residual moisture <1%) that are mechanically roughened, dust-free and primed*
– Aerated concrete (that is dust-free and primed*)
Substrates must not be wet. Cement and concrete screeds must be fully cured prior to application. Any existing dirt, loose debris and coatings should be removed mechanically. Absorbent substrates should be primed* and left to dry for at least 2 hours. Surface unevenness of up to 5mm can be filled on the previous day using Ceresit CM 16 tile adhesive. * Primed using a suitable primer from Henkel.


Pour Ceresit CM 16 into the precisely measured amount of clean cold water (as instructed in the technical data sheet) and mix using a slow speed drill until a homogenous mass without lumps is achieved. Leave for 2 minutes and then mix again. Apply the tile adhesive with a suitable notched trowel on the substrate. The size of the trowel’s teeth depends on the size of the tile. For indoor use, the tile adhesive should cover at least 65% of the tile’s backside. For outdoor uses, the back-buttering method should be followed to cover at least 90% of the tile’s backside. Place the tiles only during the open time of the adhesive. The width of the grouts should be the same and should depend on the size of the tile and exposure conditions. Excess tile adhesive can be removed with water, while hardened material can only be mechanically removed. Grouting on walls and floors can be done approximately after 8 hours and 24 hours respectively. Walkability is achieved after 24 hours. Expansion joints, corner joints and sanitary equipment surroundings shall be filled with a suitable sealant. 


Work should be carried out in dry conditions at an air and surface temperature from 5°C to 40°C. PRODUCT SAFETY: Contains cement. Strongly alkaline reaction with moisture, so protect skin and eyes. After contact wash immediately with plenty of water. After eye contact also seek medical advice.
