STRAIGHT (for moving contraction joints and floor-to-wall joints) – Approximate coverage based on a routed out joint or crack 1/4" wide by 1/2" deep and using pure epoxy (no added sand), the small kit (2-qts) will fill approximately 75 linear feet. The medium kit (2-gal) provides four times more volume – 300 linear ft.
MIXED WITH SAND (for a rigid repair of larger cracks) – For the small 2-quarts kit and using 4:1 sand to epoxy ratio, you will need approximately 20 lbs. of dry sand for the mixture to fill about 375 ft. of cracks ¼” wide and ½” deep.

Appearance – Cures gray. Adding sand or sprinkling on sand before it cures makes the surface color and texture look more like concrete. ElastiPoxy is partially paintable. When using pure epoxy, it is best to roughen up the surface first with a grinder.
You will need a small plastic pail for mixing the two compounds and a low-speed electric drill for the mixers. If needed, purchase dry, silica construction sand (with no fines) from your nearby big-box store. You will also need a small plastic watering can or a cup with a spout for pouring the pure epoxy into joints and cracks in floors. Use a masonry trowel when applying the ElastiPoxy-to-sand mixture.

Customers' feedback and tips on Repairing Cracks
Hydraulic Cement is waterproof but does not bond well to concrete. That’s why it needs an inverted V-groove. It is also very rigid – more than concrete – and does not move with the concrete. Not suitable for moving joints! After a couple years, this rigid rod gets loose and efflorescence (white powder) starts appearing around its edges, soon followed by drops of water. Using a patching compound instead will not provide a flexible and waterproof joint.
Polyurethane Caulk is both waterproof and flexible. It bonds well to the surface of dry concrete but wicking water and efflorescence gradually weaken the bond. It has no strength and easily separates due to water pressure, efflorescence, or traffic.
These common methods provide only a superficial and temporary fix. Only ElastiPoxy provides a permanent solution for flexible control joints and when mixed with sand, a rigid repair of cracks in concrete blocks and brick walls.
