Features
Receives finishes after 1.5 hours regardless of thickness Slump-free—ideal for vertical and horizontal repairs Ideal for the rapid repair of
internal concrete, screeds, renders, and concrete steps Other applications include forming ramps, falls and coves, patching around
fittings/pipework, and filling cracks and gaps
Substrate Preparation
R-61F can be applied to dry or moist screeds, provided they are set and hardened and the surface is sound and free of dust, grease, oil,
and other surface contamination. Worn or trafficked surfaces should be abraded (wire brush, angle grinder, etc.) to remove
contamination and expose a clean surface to ensure good adhesion. Very dense, smooth, impervious surfaces should be primed with
CLI N 18 Primer. Priming is not usually necessary on concrete, cement/sand, brickwork, etc., unless the surface is extremely porous.
Direct-to-earth sub-floors must have an effective damp-proof membrane.
