Surface Preparation
R-17F can be applied to dry or moist substrates, provided they are hard, sound, and free of dust, grease, oil, and other barriers to adhesion. Worn or trafficked surfaces should be mechanically prepared to remove contamination and expose a clean surface to ensure good adhesion. Very dense, smooth, impervious surfaces should be primed with sand-blinded CLI IF – 3E Solvent Free Epoxy Primer. Priming is not usually necessary on concrete, cement/sand, brickwork, etc., unless the surface is extremely porous. On absorbent substrates, the mortar must be initially applied firmly in a thin layer; after that, apply the mortar to the required thickness Product Data Sheet.
Application
Repairs: Apply the mortar with a trowel to holes, cracks, and damaged areas, ensuring that the mortar “wets” the surface by troweling it in firmly, leaving the repair proud. After about 10 minutes, trim off excess and finish with a wet trowel, sponge, or sponge float to obtain a smooth surface. This smoothing operation needs to be completed within 15 minutes of application. As soon as the R-17F repair has hardened, the surface of the floor, stair tread, etc., can be leveled, if necessary, with the appropriate CLI sub-floor smoothing compound. Smoothing and Refacing: Apply the mixed mortar with a trowel to the required thickness, considering the short working time. The material may be finished with a wet trowel after 10 to 15 minutes to provide a finish suitable for the direct application of tiles or stone. Apply at temperatures above 5°C. The finished surface must be protected against direct sunlight and drafts, which could lead to rapid drying of the surface.
