That number tells you how many epoxy kits to buy, and running short halfway through a coat is a mess you do not want. While you are down there, look for low spots, cracks, and any signs of moisture coming up through the slab. Damp concrete will not hold a coating, so sort that out before you go any further."},{"number":2,"title":"Step 2: Fill Cracks and Gaps","text":"Load a tube of concrete filler and sealant into a caulk gun and work along the base of the walls and across any cracks in the slab. Run a steady bead into each gap, then tool it smooth so it sits flush with the surface. Epoxy will telegraph every crack you leave behind, so take your time here. Let the filler set up fully before you move on to cleaning."},{"number":3,"title":"Step 3: Sweep the Floor Clean","text":"Grab a stiff push broom and sweep the entire floor, corners included. You are pulling up loose dirt, dust, and grit that would otherwise get trapped under the coating. A clean surface is the whole difference between epoxy that bonds for years and epoxy that peels in a season. Sweep it into a pile and get it out of the garage before you wet anything down."},{"number":4,"title":"Step 4: Degrease the Concrete","text":"Pour concrete cleaner and degreaser across the slab and scrub it in with the broom or a stiff brush. Garage floors soak up oil, brake dust, and road grime, and any of it left on the surface will keep the epoxy from gripping. Pay extra attention to the spots under where a car parks. Work it in, let it sit for the time on the label, then rinse."},{"number":5,"title":"Step 5: Etch the Surface","text":"Apply the etching solution and scrub it across the concrete with a stiff-bristled brush on a pole. Etching lightly roughens and opens the pores of the slab so the epoxy can key into it, almost like sanding before you paint. The surface should feel like fine sandpaper when it is done. Keep the solution moving so it works evenly and does not pool in one spot."},{"number":6,"title":"Step 6: Rinse and Dry","text":"Rinse the whole floor with a pressure washer until the water runs clear and every trace of etcher and residue is gone. Then push out the standing water with a squeegee and finish drying it with a leaf blower. The concrete has to be bone dry before any epoxy touches it, so give it plenty of time. Trapped moisture is the number one reason coatings fail."},{"number":7,"title":"Step 7: Mix and Pour the Epoxy","text":"Combine Part A and Part B of the epoxy kit and stir it thoroughly, scraping the sides so nothing goes on unmixed. Once the two parts meet, the clock starts on your working time, so mix only what you can spread before it sets. Pour the mixed coating into a roller tray lined with a liner for easy cleanup. Work in batches and keep moving."},{"number":8,"title":"Step 8: Roll on the Coating","text":"Roll the epoxy onto the floor in even, overlapping sections using a roller cover on a telescoping handle. Start at the wall farthest from the door and work your way back toward the opening so you never trap yourself in a wet corner. Keep a wet edge as you go and do not let one section dry before you blend the next into it. Steady, even passes give you a smooth, consistent coat."},{"number":9,"title":"Step 9: Broadcast Flakes and Let It Cure","text":"While the coating is still wet, toss decorative color flakes across it by hand for that speckled, professional look. Then walk away and let it cure. Most kits want about 10 hours before you step on the surface and 36 before you drive on it. The payoff is a glossy, sealed floor that wipes clean, shrugs off spills, and makes the whole garage feel finished."}],"recipe":null,"lastUpdated":"2026-07-14T00:57:11.037Z","published":"2026-07-14T00:55:26.163Z","license":"CC BY 4.0.
