An Old River City and Its Floors
Epoxy flooring in Oconto starts with a careful look at the concrete, because many of the floors here are old. Oconto incorporated as a city in 1869 and reached its peak population of 5,629 in 1910. Today about 4,609 people live here. A city that was built out more than a century ago has plenty of homes with original or early basements and garages added decades later. Those slabs need a different plan than a new subdivision floor.
Basements come first here
Oconto sits where the Oconto River empties into the bay of Green Bay. Low, river-mouth ground and older foundations often mean damp basements. Moisture rising through a slab is the most common reason basement coatings blister or peel. So before we suggest Basement Floor Epoxy, we test the slab. If the reading is high, we use a primer rated for moisture. If water is actually coming through a crack or a wall joint, we tell you that coating will not fix it, and that the water has to be handled first.
Common things we find in older Oconto basements:
- Paint or sealer from past owners that has to be ground off
- Old patches and settling cracks around floor drains
- A rough or dusty surface that sheds grit
- White efflorescence where moisture has carried salts to the surface
Winter numbers for Oconto
NOAA normals for 1991 to 2020 put Oconto's annual snowfall at 51.5 inches. The average January high is just 26.0°F, and the record low is -35°F. Those cold months mean salt on the roads and slush on the garage floor from November into spring. Garage Floor Epoxy or a Full-Flake system keeps that brine from soaking into the slab, where freeze-thaw cycles break the surface apart.
Boats, campers and shop space
Oconto has a working waterfront history and is home to Cruisers Yachts, a builder of luxury pleasure yachts. Boats are part of life here, and plenty of local garages and outbuildings store one through the winter. A boat on a trailer can drip bilge water, fuel and cleaning products. For that kind of storage bay, a Shop & Commercial Floor Epoxy system gives a thicker, chemical-resistant surface that rinses clean in spring.
Garages added over the years
In an older city, the garage is often newer than the house, and sometimes it has been rebuilt or extended more than once. That can leave a slab with a seam where two pours meet, a low spot that holds meltwater, or an old apron that has scaled from salt. We repair those areas before coating so the new floor sits flat and drains toward the door. Oconto had 2,040 housing units in 2000 and 2,175 in 2020, so most of the floors we coat here are on existing homes rather than new builds. Expect us to spend more time on prep than on a brand-new slab, and expect the quote to show exactly what that prep is.
How we price an Oconto floor
We measure, test moisture and note every repair before we write a number down. Two basements the same size can differ a lot in cost if one needs old paint removed and the other does not. Your written quote lists the prep, the system and the number of coats. Call (920) 717-3693 or get a free estimate to set up a visit.

Oconto Questions
My Oconto basement feels damp. Can it still be coated?
Often, yes. We test the slab for moisture first. A moderate reading can be handled with a moisture-tolerant primer under the coating. If water is actively coming in, that has to be fixed before any coating goes down, and we will say so.
Can you coat over the old paint on my basement floor?
No. Old paint and sealers are ground off so the new coating bonds to bare concrete. Coating over paint is one of the most common reasons floors peel.
What floor works best for winter boat storage?
A thicker shop-grade epoxy with a chemical-resistant topcoat. It handles drips of fuel, oil and cleaners, and the floor rinses clean when the boat goes back in the water.
