Sikafloor-6 Chapdur Grey (KH) cures monolithically to produce a dense, high abrasion resistan surface. The floors have similar chemical limitations as other cementitious products.

According to the ambient temoerature and the kind of cement used in the slab, waiting time should be:

3 - 6 kg per m²
4 kg / m² for normal traffic area
5 - 6 kg / m² for heavy traffic area

As soon as the substrate of concrete has reached plasticity (after bleeding, but before setting begins) smooth out the surfacing of the freshly poured concrete and level off with a vibrating straight edge.

Sprinkle the Sikafloor-6 Chapdur Grey (KH) mixture "by hand" over the smooth wet surface, at a rate of 3 - 6 kg / m². Allow the Sikafloor-6 Chapdur Grey (KH) to absorb moisture from the substrate and when evenly moist, consolidate, power float the surface of the Sikafloor-6 Chapdur Grey (KH).
 

Smoothing out: as soon as the mixture becomes plastic or just as it is about to set, carry out a pre-smoothing operation with the power float machine running at a low speed but fitted with a metal blade's at a minimum inclination. The final smoothing operation (if necessary) is carried out some time later, but with the power float machine running at high speed.

Sikafloor-6 Chapdur Grey (KH) mixture surface must be protected to prevent rapid water loss which can result in surface cracks. Therefore, approved curing system shall be applied.
