Epoxy Flooring in Green Bay, WI

Epoxy flooring in Green Bay has to survive a long, wet winter. Wikipedia puts the city's average snowfall at 55.6 inches a year, and the average January day tops out around 25.5°F. All that snow means plows and salt on every road, and the salty slush rides into your garage on the tires. Bare concrete soaks it up. A well-bonded coating keeps that brine on the surface so you can push it out the door.

Where the salt comes from

Salt is part of daily life here. Wikipedia lists it among the main cargoes at the Port of Green Bay, along with coal, limestone and cement, and the port moved 1.99 million tons of cargo in 2015. In winter, road salt shows up as white crust on garage floors from De Pere to Suamico. On an uncoated slab, repeated wetting, freezing and thawing with salty water loosens the top layer of concrete. You see it as flaking near the door, rough patches under the tires and a floor that sheds dust no matter how often you sweep. A garage floor coating stops that cycle at the surface.

Homes from every decade

Green Bay's housing spans more than a century. American Community Survey figures for 2019 to 2023, as summarized by Point2Homes, give a median year built of 1971. About 13.7% of homes went up before 1940, 15.5% in the 1950s and 17.3% in the 1970s, while only about 4.5% were built in 2010 or later. That means most garage and basement slabs we see here are several decades old. Some carry old paint, sealers or patches. Some have settled or cracked. Before we price a floor, we look for all of it, because two garages the same size can need very different prep. When you collect quotes from epoxy flooring contractors, ask each one to name the prep steps for your slab, not just the finish.

Humid air, cold slabs

Green Bay is humid. Wikipedia lists an annual average relative humidity of 72.8%, highest in fall and winter. The EPA suggests keeping indoor humidity below 60%, ideally 30 to 50%. Basement floors sit against cool ground, so in summer, humid air can condense on them, and moisture can also rise up through the slab from below. That vapor is the main reason basement coatings bubble or let go. We test before we recommend anything. Where moisture is present, we use a primer rated for it or tell you to fix the water source first.

Wisconsin's health department says about 1 in 10 homes in the state has high radon, and that radon enters through the foundation. Test kits run about $10 to $30. A floor coating is not a radon system, so if you plan to finish a basement, test first.

The systems we install

• Garage floor epoxy: a thick 100% solids base coat with a tough clear topcoat, the standard for attached and detached garages.
• Full-flake floors: vinyl flakes broadcast into the base until the floor is fully covered. They hide salt spots and add grip.
• Polyaspartic coatings: fast-curing and UV-stable, with a wider temperature window than epoxy. Useful in shoulder seasons and for same-week parking.
• Basement floor epoxy: systems matched to the moisture reading, for laundry rooms, rec rooms and storage spaces.
• Metallic epoxy: a poured, swirled finish for finished basements, bars and home gyms.
• Shop and commercial floors: heavier builds for trucks, forklifts, fluids and daily traffic.

Timing around the weather

HomeGuide says epoxy should be applied between 60°F and 85°F with humidity under 85%, while polyaspartic can be applied across a far wider range. From late fall into spring, an unheated Green Bay garage is often below that epoxy range. We check the slab temperature, can heat the space, and lean on polyaspartic topcoats when the cold is the limiting factor. If a day is wrong for the product, we reschedule.

We are based around Green Bay and cover the rest of Brown County plus the towns north and east along the bay. That includes De Pere, Ashwaubenon, Allouez, Bellevue, Howard, Suamico, Hobart, Ledgeview, Lawrence, Scott, Humboldt, Denmark, Pulaski, Wrightstown and Greenleaf, with trips out to Seymour, Little Suamico, Oconto, Luxemburg, Kewaunee and Algoma. The floors change as you move out from the city. In Green Bay itself, about a third of homes were built before 1960, so we see plenty of older, patched slabs. Suamico, by contrast, has mostly developed since 1980, and its garages tend to be newer and larger. Lakeshore towns like Kewaunee and Algoma sit right on Lake Michigan. Our epoxy installers handle the newer Suamico garages and the older patched floors in the city the same way: test, grind, repair, then coat. Each town page covers what we know about the homes there.
