Consumption

Consumption

Average consumption : 3 kg to 6 kg per m2 , depend on job requirement:

Light duty

3 kg/m2

Medium duty

4 - 5 kg/m2

Heavy duty

6 kg/m2

For Sika® Chapdur® Colour should be minimum 5 kg/m2. Yielding a surface strengthening coat of approx 2-3 mm thickness.
Application steps

SUBSTRATE PREPARATION

The concrete slab should be at least 15 cm thick, the concrete should contain an adequate proportion of cement. It is recommended to add a suitable Sika concrete admixture to improve its properties (e.g. Sikament) Level the freshly poured concrete by means of a vibrating beam. As soon as the plasticity permits, smooth the concrete preferably by using a mechanical trowel.
