How to Apply Concrete Saver InstaPatch Concrete Repair

Surface Preparation

New concrete must cure 30 days at 70°F (21°C) before repairs are made. Remove all dirt, grease, oil, salt or other contaminants by washing surface with 3500 System Pure Strength Cleaner/Degreaser, commercial detergent or other suitable cleaner. Rinse thoroughly with fresh, clean water. Remove all loose, unsound, or deteriorated concrete.

Small hairline cracks must be chased using a v-shaped diamond crack chasing blade on a hand held grinder. The crack should be opened to a minimum of ¼ inch wide. Any oil or grease that may have seeped into a crack and contaminated the edge of the concrete must be removed by grinding if washing is not sufficient. Use dry silica sand to fill deep cracks leaving a depth of ¼ inch down from the surface. The InstaPatch will soak into the silica and fortify the patch.

Application

InstaPatch is suitable for application temperature down to -5°F (-20.5°C). Within one minute of mixing, pour InstaPatch into the crack to be filled. Fill the crack to a slight excess and allow to cure. InstaPatch will cure in 10- 15 minutes. Once cured, and the material cannot be indented by a thumbnail, the excess material can be removed by grinding to a flush surface.

Note : InstaPatch must be profiled by grinding or sanding if it is going to be topcoated.
