Substrate preparation: 
Substrates must be structurally sound and free from separating layers, cracks, loose parts, pinholes and burrs. Remove grease, wax, cement slurry and all other adhesion-reducing substances. Sand the substrate. Then prime the substrates.

Wear appropriate protective clothing during application, such as: safety glasses, disposable gloves, and respiratory masks if necessary. Apply the primer and coating using a squeegee or paint roller. Apply the material quickly and evenly. Highly absorbent substrates must be primed again. We recommend sanding the primer with BK-705 quartz sand if it is not to be further processed on the same day.
