HARDFACE CEMENTITIOUS HARDENER POWDER FOR NEW CONCRETE FLOORS

DIRECTION FOR USE

hardface should be applied at an even application rate. It is recommended that the floor be marked off into bays of known area. Sufficient materials should then be laid out to meet the recommended spread rate.

hardface is applied in two stages.

• Apply two thirds of the required material to the concrete ensuring uniform distribution.
• Allow applied material to absorb moisture from the concrete surface; a uniform darker color will be apparent.
• Using a wooden float, work hardface into the concrete ensuring material becomes an integral part of the surface.
• Apply the balance of material. Again wait until material has obtained a darker color before floating with a wooden float.
• When surface is sufficiently firm enough to take the weight of a man leaving only minor indentations, hardface should be finished off by means of a power trowel. A smooth slip resistant finish can be obtained, but the surface should not be overworked.
• If manual finishing with steel trowels is to be undertaken, this should take place before concrete becomes firm enough to take foot traffic.

Curing:

Proper curing of concrete floors treated with hardface is essential to the physical properties of the finished floor. The use of polythene sheeting, wet hessian and damp sand or ponding are not recommended. The use of salt water or brackish water should not be considered under any circumstances.
