Look closely at your garage floor, patio, or pool deck, and you are likely to see signs of aging: thin hairline cracks spiderwebbing across the surface or small pits from years of wear and tear.
A common concern we hear from property owners online is: “My concrete has surface damage. Do I need to tear it out and pour a completely new slab before I can get a professional coating?”
The good news is that minor surface defects do not mean you need a costly demolition crew. At Poly Shield Coatings, we specialize in targeted concrete floor repair as a foundational part of our standard preparation process. While our process follows the natural level and slope of your existing slab, we take great care to smooth out surface imperfections so your new coating bonds flawlessly. Here is how we treat those cracks and pits before the first layer of coating ever touches it.
Step 1: Cleaning and Opening the Fractures
If you simply pour a filler over a dusty, dirty crack, it will pop right back out within a few months. The Poly Shield Coatings crew begins by prepping the damaged areas.
Using specialized hand grinders, we carefully chase out surface cracks and pits. This process clears away loose debris, crumbling concrete, and hidden dirt, creating clean edges. This mechanical preparation ensures our repair compounds can bond directly to solid concrete.
Step 2: Injecting High-Strength Mending Compounds
Once the cracks and pits are cleaned and opened, we apply our specialized industrial mending compounds. We do not use standard retail caulk or cheap concrete patch mixes from home improvement stores, which can shrink and pull away as they dry.
Poly Shield Coatings utilizes low-viscosity, fast-curing repair materials. These liquids are engineered to dive into the surface fractures, filling the void. As they cure, they undergo a chemical reaction that fuses the concrete edges back together, curing incredibly hard so the defect doesn’t mirror through your final brilliant topcoat.
Step 3: Diamond Grinding for a Smooth Finish
After our mending compounds have fully cured, our team uses industrial planetary diamond grinders across the entire slab. Our grinders follow the exact contour of your floor, removing the slick top layer of concrete while grinding the repaired patches down until they are completely flush with the surrounding surface.
While diamond grinding will not change the pitch, slope, or level of an unevenly poured slab, it does eliminate the rough texture of old pits and cracks. When our grinding process is complete, you are left with a smooth, uniform, and porous surface perfectly prepared to accept our multi-layer polyurea and polyaspartic coating system.
A Flawless Foundation for Your Coating
While Poly Shield Coatings cannot be responsible for the structural integrity or shifting of a concrete slab poured by someone else, we can control how well our product bonds to it. By taking the time to mechanically mend and smooth out surface flaws, we ensure your final floor looks seamless, beautiful, and stays protected from the top down for years to come.
