Step by step

Preparation & mixing

Adhesive mortar must have set and dried sufficiently and the joints must be free of adhesive residues and dirt.
Pour the required amount of CE 42  into a bucket with clean, clear water - use the correct mixing ratio with water as defined on the packaging. Mix with an electric driller until you achieve a homogenous mixture, free of lumps. Leave for 3 minutes to mature, then stir again.


Apply the mortar with a grouting tool on wall or floor in such a way that the joint is completely filled.


After the grout has started to set (fingertest), clean the area by wiping with a wet sponge and little water. The second cleaning should be done in diagonal movements with clean water.
