Application
Substrate preparation The substrate must have sufficient compressive strength (minimum 25 N/mm²). The surface must be flat, slightly rough, dark and dry, cleaned of all contaminants. If in doubt, make a reference area. Parts of substrate with insufficient strength, cement slurry and fragments contaminated with oils or other anti-adhesive materials, must be removed mechanically, e.g., by means of grinding or milling. Before the material application, the substrate must have open pores. Immediately before the material application, the substrate must be dusted and vacuumed.
