Garage Floor Epoxy in West Allis, WI

What winter does to a garage slab

From November through March, a West Allis garage floor is wet more often than it is dry. Snow packs into the wheel wells, melts overnight and leaves a puddle of brine under each tire. That salty water seeps into the top of the concrete. When the garage drops below freezing, the trapped water expands. After a few seasons the surface starts to scale: thin flakes pop off, small craters appear and the aggregate shows through. Add oil drips, dropped tools and the dust that rises from weakened concrete, and the floor ends up looking far older than it is.

Epoxy breaks that cycle by sealing the slab so salt water never gets into the pores. But the coating is only as good as the bond underneath it. A floor that has already started to scale needs the loose material removed and the pits filled before anything goes on top. That is why grinding and repair are the largest part of every garage job we do.

Our prep is the difference

We do not acid etch, and we do not roll paint over a dirty slab. We diamond grind the entire floor with dust-collecting equipment, which opens the pores of the concrete and takes off old sealers, salt residue and the weak top layer. Then we look closely at what is left. Scaled areas near the door get a polymer repair mortar. Control joints are cleaned out, and cracks are routed and filled. We take moisture and temperature readings, because both affect which primer and base coat we use. Only then does the coating go down.

The coating system

A standard garage floor from us has three parts. First is a high-solids epoxy base coat, applied thick enough to fill the profile left by grinding and lock into the concrete. Second, if you like, is a light scatter of decorative flake for color and texture. Third is a clear, UV-stable topcoat with fine aggregate mixed in, so the floor has grip when it is wet. We pick the topcoat chemistry based on how you use the space. Polyaspartic tops hold up better to hot tire pickup and sunlight from an open door, while urethane tops add scratch resistance in a workshop.

Color choices run from light grays that brighten a dim alley garage to darker charcoals and tans that hide road grime. We bring sample boards to the estimate so you can see them in your own light.

Alley garages and older slabs

A lot of the garages we coat are detached structures at the back of the lot, built decades ago and reached from the alley. Their floors are often thinner than modern slabs and were poured without a vapor barrier. Some slope toward the door, and some have settled unevenly. We work with those quirks instead of ignoring them. Low spots can be built up with repair material, heaved sections can sometimes be ground down and drains can be cleaned out so water still runs where it should. If a slab is cracked through and moving, we will tell you before we sell you a coating.

Cold-weather installs

Epoxy needs warmth to cure properly. In an unheated garage in late fall or winter, the slab can sit at temperatures where a standard epoxy would stay soft for days or cure with a cloudy, weak surface. We measure the actual slab temperature with an infrared thermometer. If it is close, we bring heaters and keep the space warm through the cure. If it is too cold, we suggest a polyaspartic system that cures at lower temperatures, or we book you for spring. Either way, you will know the plan before we start.

Living with your new floor

Care is simple. Squeegee standing slush out the door during the winter so it does not refreeze into a slick patch. Sweep or use a dust mop for dry dirt. A few times a year, wash with a mild cleaner and a soft mop or deck brush. Avoid strong solvents and do not drag sharp metal across the surface. Put a pad under kickstands and jack stands. With that kind of basic care, a properly installed epoxy floor will look good and protect your concrete for many years.
