What is a concrete slab control joint & why do we need control joints in concrete?A control joint controls where and how a shrinkage crack appears in poured concrete, and it allows for thermal expansion or contraction without additional damage. Without a control joint, cracks in concrete floors, walls, or ceilings appear at stress points in uneven, diagonal, or other patterns in locations where they may be unsightly or may cause damage such as cracks in ceramic tile or other floor coverings, or may be traced to leaks.

You mix the A & B together, and then add the sand to a 'pasty' consistency and use for filling control joints, saw cuts large cracks, divots, spalls and forming base coves with a cove tool. When forming coves use the appropriate sized cove tool and figure as a rough estimate of 50 lineal feet of cove per 1 gallon of mixed A & B liquids.
For best results with cracks run a small hand grinder through cracks to V them out. Apply before cleaning and etching. Cures to a rock hard finish that is stronger than concrete and bonds perfectly with any of our epoxies.
Used to make your floor ultra-smooth prior to applying our epoxies. Comes in 1 gal size and 3 gal size. Coverage is dependent on crack sizes and application and sand mix content.Note: If filling in expansion joints (joints with flexible materials in them) that incur slab movement, we recommend you use our Flexible Joint Sealer.For saw cuts and control joints you can leave unfilled and run the epoxy lightly in an out of the joints, this will make them look like finished grout lines.
This is done more often than not but if you want one solid surface then by all means you can fill them in with this product or our ready coat crack repair compound. Epoxy Concrete Crack DirectionsRepair area must be clean and dry, see Must Read tab.
