Best results

For best results, thoroughly prepare the surface by removing dust, loose concrete, dirt, oil and other contaminants and ensure the area is dry before application. Mix equal parts of each component and apply with a putty knife or similar tool to fill cracks, spalls and holes. Most coatings or sealers can be applied directly over the patch while uncured, making it highly efficient in both renovation and maintenance workflows. Typical curing time to support foot and vehicle traffic is 8–12 hours at standard room temperature.
