Surface Preparation

Remove all cracked, spalled and deteriorated concrete to create a solid surface. Remove loose concrete and rust using a wire brush. Wash the area clean with water. Remove standing water and leave surface damp before applying Instant Patching Cement.


Mix only what may be applied within ten minutes. Combine Instant Patching Cement in a bucket with water to achieve a putty like consistency. For a stronger bond, replace water with Stone Mason® Acyli-Bond.


Fill Instant Patching Cement to allow sculpting after product has initially set. After initial setting and within ten minutes, shave excess Instant Patching Cement to desired shape. Allow to harden. Open to foot traffic in four hours.


Apply in temperatures between -7°C (20°F) to 49°C (120°F). If Acryli Bond us used as mixing liquid, do not apply if temp is below 5°C (40°F)
