Technical Information

Surface preparation: Concrete must have a minimum 28 day cure prior to application. Clean the joint area to be injected. The area must be dry prior to application. Clean the surface and remove all unsound concrete, dust and debris. Prepare surface using a twisted wire wheel for spalls. Cut perimeter of damage with dry diamond blade. Mixing: Stir well before using. Material may separate during long term storage. Mix only in small workable quantities in equal 1:1 ratio. Application: Mix small amounts in an easy dispensing container. Pour directly into crack or over sand in crack base. Work the repair area quickly. Screed to finished grade and allow to set. For better finished repair surface, pour grout mix slightly high above the finished grade. Allow to set and grind using a grinder fitted with a diamond impregnated cup wheel. Work in circular motion to grind/smooth to finished grade. Seal the surface using mixed product neat with no sand. Note for First Time Users: This is a very fast set product, it is advisable to test this product before using it in an application. Become familiar with how this product works. Please note: It is always recommended to test the product in a small, inconspicuous area (on the same concrete substrate) for desired results prior to application.
