KWIK MIX 44 lb. Grey Build and Restore Concrete Patch is a high strength, rapid developing, commercial grade concrete patch containing 2 Portland Cements, silica fume, active silicates, special aggregate, a super plasticizer, defoamer and a set-accelerator. The patch will form a very dense patch that will resist chlorides and acids. Specifically designed for remedial patching ,repairing and restoration of worn or damaged concrete structures and surfaces. Suggested uses are curbs, roads, sidewalks, bridges, pools, decks, foundations, ornamental casts and other building applications. For best results, after the initial set has taken place the surface may be moistened and troweled to a smooth finish. For maximum strength, cure the surface (keep damp) for a 24 hour period. For deep depressions, the patch should be placed in maximum 2 inch deep layers.
Features
- Very low chloride permeability
- High salt resistance
