Description of floor hardener
Sikafloor chapdur is a floor hardener mechanically applied onto surface of concrete slab before final setting has taken place to increase the abrasion and mechanical impact resistance of the floor.
Sikafloor chapdur is composed of non metallic very hard granular material, pigment and portland cement.
Application of Floor Hardener of Sika Chapdur
Wetting out and consolidation
Broadcast the sikafloor chapdur onto substrate before final setting has taken place.
Allow the sikafloor chapdur to absorb moisture from the substrate and when evenly moist, power float the sikafloor chapdur into the surface to consolidate.
Smoothening out
As soon as the mixture shows uniformity and becomes plastic carry out the pre-smoothening operation using the power float fitted with metal blades at a minimum inclination and low speed.
The final smoothening operation (if necessary) should be carried out later with the power float running at high speed.
Curing
The sikafloor chapdur mixture surface must be protected to prevent rapid water loss, which may results cracks. Therefore approved curing system must be applied. Please consult our technical department.
Contraction joint
Contraction joint must be sawed cut max. 24 hours after finishing smoothening work.
