Walk into any older garage in Denver or Colorado Springs, and you’ll likely see it: the "surface rot." Whether it’s chunks of concrete popping off from winter salt damage (spalling) or small, jagged holes where the surface has simply crumbled (pitting), it’s more than just an eyesore. It’s a sign that your concrete is structurally deteriorating.
At Twin Brothers Coatings, we get asked all the time: "Is my floor too far gone to be coated?" The good news is that with the right repair process, we can usually make a damaged floor look—and perform—better than the day it was poured.
Why You Can’t Just "Paint Over" It
If you try to apply a cheap DIY coating or even a professional thin-film epoxy over pitted concrete, the results are a disaster. The coating will sink into the holes, highlighting the imperfections rather than hiding them. Even worse, the air trapped in those pits will often "outgas" as the coating cures, leaving you with a floor full of tiny bubbles.
The Twin Brothers Restoration Process
We don’t just fill holes; we rebuild the surface. Here is how we handle heavily damaged Front Range concrete:
Mechanical Cleaning: First, we diamond grind the entire floor. This removes the loose, "rotten" concrete and ensures we are bonding to a solid, healthy foundation.
Industrial Menders: We use high-strength, rapid-cure polyurea menders. These materials have a very low viscosity, allowing them to deep-dive into the pits and cracks. Unlike standard concrete caulk, these menders actually bond to the sidewalls of the repair area and become stronger than the concrete itself.
The "Flush" Finish: Once the mender has cured, we grind it again so it is perfectly flush with the rest of the floor. This creates a seamless, "glass-smooth" canvas for our base coat.
Most people think they need a new driveway or a new garage slab when they see pitting. But once we grind out the rot and fill those pits with our industrial menders, that floor is actually more durable than a brand-new pour because it’s finally sealed against the elements.
— Alex, Co-OwnerWhy Colorado Concrete Needs the Extra Help
Because of the heavy bentonite clay in our soil and the extreme temperature swings along the Front Range, concrete is constantly moving. If those pits and cracks aren't repaired with a material that has a bit of "flex," the repairs will just pop back out next winter. Our menders are designed to move with your floor, ensuring the repair is permanent.
By the time we apply our flake system and that final 85% solids polyaspartic topcoat, those ugly pits are a distant memory, and your floor is fully armored against future damage.
