Visually inspect the garage door springs, cables, rollers, hinges, and tracks. Look for loose hardware, dirt, and debris. Listen if the door is making grinding or scraping noises. Next, lubricate, tighten, and balance the door. Regular garage door maintenance helps you can avoid sudden breakdowns and expensive repairs.
You cannot waterproof a residential garage floor, but you can come close using a membrane barrier under the floor and an epoxy coating on top. Polyurethane and acrylic coatings are the next most effective, and penetrating sealers are the least able to block moisture.
Clean small cracks with a wire brush, a hammer and a cold chisel. Prepare a larger crack using an angle grinder with a crack chasing wheel. Vacuum away the debris. Fill small cracks with RTG Crack Filler. Fill medium cracks with EpoxyShield Patch & Repair. Fill large cracks with Epoxy Patching System.
Concrete cracks are easy to repair so long as they’re not structural. Spalling is the pockmarks that come from freezing and thawing. Aging causes pitting, which looks like spalling but with deeper holes. Salt moving through water to the concrete surface causes laitance and efflorescence. While both are usually harmless, efflorescence can be a sign of structural problems. Consistent puddles of water can point to a serious underlying issue.
Use a de-greaser to remove oil from the surface. Use a wire brush, or a grinder or an acid-substitute, to prepare the concrete. For large areas use a floor buffer with a grinding attachment. Vacuum up loose material. Trowel a patch kit onto the surface.
How do you fix concrete garage floor spalling and pitting? Test for and remove weakened adjacent areas; clean and prepare the surface to be repaired; and patch the area with an epoxy-based topping. Before fixing the problem, though, check for serious moisture or structural issues that would require professional help to fix.
