Reduces Downtime
Strength
Easy Application

Gar-Rock is an all-weather, fast-setting, chemical action concrete patching material designed to patch concrete surfaces where quick permanent repairs are desired. Gar-Rock can be used at below freezing temperatures. It exhibits high compressive and flexural strength, and it forms a permanent bond to ordinary concrete. Gar-Rock is mixed with water only. It can be used in damp areas, and the material does not emit any toxic fumes.

Method	Description
Trowel	Gar-Rock should only be applied to properly prepared surfaces. A sound base is essential for effective repairs. Chip out the area to be repaired approximately 1/4” (6.35 mm) deep. Remove all oil, grease, dust, dirt, and loose concrete material. Dampen the sides and the bottom of the hole. Remove any standing water from the area to be repaired. Use a clean mortar box and hoe or paddle type mortar mixer to mix the Gar-Rock. Only 3 1/2 pints (1.66 liters) of clean water are required to completely mix each 45 pound (20.4 kg) pail. Excess water reduces the strength of the cured product. Gar-Rock should be applied immediately after it is mixed. Place or force the mix into the prepared area and trowel until a smooth level surface has been reached. Work the material well into the base to insure a good bond. Do not overwork or overtrowel, and do not attempt to re-temper the mixture with additional water. For deep repairs, up to 25 lbs. (11.3 kg) of 3/8” (9.53 mm) aggregate can be added to increase yield. The aggregate mix should be applied up to 1/4” (6.35 mm) of the surface. Gar-Rock is then used to smooth and level the repair.
