The DIY kits for sale often have a high failure rate due to improper installations. To have any coatings stand up against moisture, weather, UV, wear and tear, vehicle traffic, chemical spills, and foot traffic, proper prep work, paired with quality products, is a must! Concrete grinding with appropriate dust extraction is the ONLY way to prepare any job and ensure a proper bond to any surface. This preparation process is one of the biggest reasons DIY kits fail after the first year. The kits recommend washing with water to prepare the surface, which introduces unwanted water into the concrete. After the product is installed, any water in the concrete will evaporate, causing certain de-lamination.
