Armor Coating Co.

Concrete Floor Coatings in Duluth, MN

Road salt tracked in all winter. Freeze-thaw moisture seeping through the slab. Hot tire pickup in summer. Duluth garage floors and concrete surfaces take a beating that off-the-shelf epoxy kits can’t handle.

Armor Coating Co. installs polyaspartic and polyurea concrete coatings that are 4X stronger than epoxy, UV-stable, and fully cured in a single day — engineered for the conditions along Lake Superior.

Why Duluth Floors Need More Than Epoxy

Duluth logs 80+ inches of snow annually, and temperatures swing from -30°F to summer heat — sometimes in the same week during spring. That constant freeze-thaw cycling cracks and delaminates standard epoxy coatings within a few years.

Our polyaspartic/polyurea system is built differently:

Frequently Asked Questions

Every project is different, so we provide free, no-pressure estimates based on your specific space. Cost depends on square footage, the condition of your concrete, and which coating system fits your needs. Many Duluth garages need salt pit repair or spalling fixes before coating — we handle that prep work on the same day. Give us a call or fill out our quote form and we’ll walk through it with you.

Most residential projects — garage floors, patios, walkways — are completed in a single day. Our polyaspartic/polyurea system cures fast. You can walk on it within 4–6 hours and park on it in 24 hours. No week-long garage shutdowns.

Polyaspartic and polyurea coatings are 4X stronger than epoxy and 98% more flexible. They cure in hours instead of days, won’t yellow from UV exposure, and resist chemicals, hot tire pickup, and abrasion far better than epoxy. Epoxy also becomes brittle in extreme cold — a real problem in Duluth. Our system stays flexible through the temperature swings that destroy epoxy within a few years up here.

Yes. Polyaspartic coatings can be applied in temperatures as low as -40°F, which means we install year-round — even in January. Most epoxy installers shut down when temps drop because epoxy won’t cure properly in the cold. That’s not an issue with our system. If you’ve got a heated or unheated garage, we can coat it regardless of what it’s doing outside.

That’s exactly what our system is built for. Duluth gets 80+ inches of snow a year, and spring temperatures can swing above and below freezing in the same day. Every one of those cycles forces moisture to expand and contract inside unprotected concrete — widening cracks and causing spalling. Our polyurea coating is 98% more flexible than epoxy, so it moves with the slab instead of cracking against it. It also seals the surface so moisture and de-icing chemicals can’t penetrate in the first place.

In Duluth, road salt and brine are unavoidable — especially if you’re driving the steep grades on Skyline Parkway, Piedmont, or coming up from Park Point. Every time you pull into your garage, salted slush melts off your vehicle and soaks into unprotected concrete. Over time, that salt saturates the slab with extra moisture, and as it freezes, the expansion causes pitting and spalling. A polyurea coating creates a sealed, non-porous barrier across the entire surface. Salt, brine, and snowmelt sit on top where you can sweep or hose them away instead of eating into your concrete.

We install year-round, but the most popular windows are spring — after the last salt application — and early fall — before winter hits. That said, there’s no wrong time. Polyaspartic cures in any temperature, so even mid-winter installs are on the table. Summer is our busiest season, so if you’re planning a warm-weather project, booking a few weeks ahead locks in your spot.

Absolutely. A big part of our work in the Duluth area is detached garages in neighborhoods like Lakeside and Lester Park, pole barns in the surrounding rural areas, and seasonal lake cabins. These structures are often unheated, which means even more extreme temperature swings than an attached garage. Our polyurea system handles that — it stays flexible and bonded to the slab whether the space is climate-controlled or not.
