Garage Floor Epoxy in Dubuque, IA

Garage floor epoxy is the job most Dubuque homeowners call us about, and winter is the reason. Dubuque averages about 42.5 inches of snow a year. The city's steep, winding streets get a careful layer of salt, and every trip home brings a load of salty slush into the garage. Bare concrete drinks that brine in. A ground, coated slab keeps it sitting on top, where a squeegee or a hose can move it out the door.

What salt and cold do to bare concrete

Concrete has tiny open pores. Brine soaks in, and when the slab drops below freezing the water expands inside them. Salt makes it worse as it dries and crystallizes. Repeat that through a December-to-March season and the top layer starts to flake off. In Dubuque, where January nights average about 11 degrees Fahrenheit, the first few feet inside the overhead door see the hardest wear. That is where we usually find scaling, pitting and white salt rings.

How to tell your slab needs work

• The surface is flaking or rough near the door or under the tires
• White, crusty rings show where puddles dried
• Oil and transmission fluid stains have soaked in
• Dust keeps coming back after you sweep
• A previous paint or kit coating is peeling in the tire paths
• Cracks, broken joint edges or low spots hold water

Alley garages, tuck-unders and new builds

Dubuque has a lot of older housing. Census figures for 2019 to 2023 show 30.4% of the city's homes were built in 1939 or earlier. In older neighborhoods that often means a detached garage on an alley with a thin, sloped or patched slab. Hillside homes may have a tuck-under garage set into the slope, sharing a wall with the basement, where moisture can show up at the back of the floor. Newer homes on the West End and in Asbury usually have attached two- or three-car garages with flatter, younger concrete. We plan prep around the garage you actually have.

Prep is where the floor is won or lost

Most peeling garage floors failed on day one because the coating never bonded. Acid etching cleans the surface but leaves weak, salt-soaked concrete and old sealers in place. We diamond grind the entire slab, edges included, vacuum it, degrease oil spots and fill cracks and pits. Any old paint or kit coating gets ground off before the base coat goes down.

Picking a finish for a Dubuque garage

A full flake floor is the most forgiving choice for winter. The chips hide salt film between washes and give the surface grip when it is wet. A solid color with a light chip or anti-slip additive in the topcoat looks cleaner and still adds traction. A polyaspartic topcoat over either one adds UV and abrasion resistance and gets you parking sooner. We bring samples so you can see them under your own garage lights.

Keeping it looking right

A coated floor still needs some winter care. Push meltwater out with a floor squeegee, rinse the floor every few weeks during salt season and put a containment mat under each vehicle if you like. Keep metal shovel edges off the surface.
