Epoxy Flooring
Epoxy floor coatings in solid color, flake, metallic and quartz finishes for homes and businesses. Every slab is diamond ground and moisture tested, and a UV-stable polyaspartic topcoat seals the floor.

Concrete repair is the first step when a floor is pitted from road salt or cracked across the slab. The same goes for a garage where the old epoxy kit peeled. Slab Lab Coatings fixes cracks, pits and spalled spots in garage, basement and shop floors. When damage covers most of the floor, concrete resurfacing gives the slab a new top layer.
We are based in Otsego and work across the Twin Cities metro. Repairs get a floor ready for a garage floor coating or a basement floor coating. Every slab is diamond ground and moisture tested. The free estimate spells out the system, the mil thickness and the repairs for your floor.

In a Minnesota winter, road salt rides into the garage on your car. The slush melts, and salty water soaks into the top of the slab. Wet concrete that freezes and thaws over and over can scale. Scaling is when thin flakes peel off the top.
Concrete industry guidance says deicing salt makes scaling worse, because it keeps the surface wetter and adds freeze-thaw cycles. Water grows about 9 percent in volume as it turns to ice, which builds stress inside wet concrete. Pieces that break loose are spalls, and small cavities across the surface are pitting.
The Minnesota Pollution Control Agency estimates 365,000 tons of road salt go down in the Twin Cities metro each year. The City of Otsego, where we are based, stocks about 900 tons of salt each winter. Slab Lab Coatings is rated 4.8 on Google, and customers' reviews describe salt-damaged, pitted garage floors we repaired and coated.
Every repair starts with diamond grinding. A peeling epoxy kit or floor paint is ground away, so patches and the new coating bond to bare concrete. The grinder also takes off the weak, flaking top layer of a scaled slab.
Concrete crack repair comes next, starting with crack chasing. Chasing widens each crack into a clean V-shaped groove, which gives the filler solid concrete to bond to. Once the filler sets, it is ground flush with the floor.
Pits and spalled spots are cleaned out, patched and ground flush the same way. Slab Lab Coatings was founded by a former coating inspector. Sound, bare concrete is one of the prep standards a coating inspector checks for. Moisture testing is on that list too, since coating makers say not to coat concrete holding too much moisture.
Patch material does not match the color of old concrete. When scaling covers most of a floor, a slab full of patches looks spotty. Concrete resurfacing covers the whole slab with a thin concrete overlay after the grinding and repairs. A self-leveling overlay is mixed to flow, so it fills low spots and leaves a flat base.
An overlay can be the finished floor, or it can take a flake or solid color coating on top. Many resurfacers are polymer-modified cement blends made to bond in thin layers over worn or scaled concrete. For patios and pool decks, Rubber Stone rubber surfacing is another overlay that goes over old concrete.
A repair is only as strong as the concrete it bonds to, so some slabs are past a surface fix. Industry guidance says slabs with severe, spreading scaling may not be practical to fix. Coating makers also say not to coat loose or unsound concrete. A slab that has sunk or broken apart needs a concrete contractor first.

From the first call to the final topcoat, here is how it goes.
Call or text (612) 702-9724, or send the form. We look at the slab and put the system, repairs, mil thickness and price in writing.
We diamond grind the slab with dust extraction to open the surface for a strong bond. Then we test the concrete for moisture.
We fill cracks and chips, including salt pits near the door. The coating goes down over sound, smooth concrete.
A high-solids, self-priming epoxy or polyaspartic base coat goes down over the ground slab. This is the layer that bonds to the concrete.
We broadcast polymer flake across the wet base coat until it is fully covered. Then we scrape off the excess for a consistent texture and grip.
A scratch-resistant, UV-stable polyaspartic topcoat seals the floor and hardens in 6 to 8 hours. The crew leaves care instructions and tells you when to park.

About 75 days a year the temperature swings across freezing in the Twin Cities. Our polyaspartic and polyurea systems are chosen for that and for road salt.
Most garages are coated in one day. One Google review describes a three-stall garage done between 8 in the morning and 2 in the afternoon. Pick your look from two dozen flake blends.

Josh was amazing to work with. He personally called after I did the Facebook quote and scheduled an estimate for the next day. He got me on the schedule within 2 weeks. The crew arrived at 8am sharp, and were gone by 2pm doing my 3 stall garage. It’s been 2 months and it’s still the favorite update we’ve done to our house since buying. I can’t recommend Josh and Slab Labs enough for getting your garage floor upgraded.
We were so happy with the new garage floor coating Slab Lab did in our garage. Josh was very informative and helpful every step of the way. The workers, Rey and Alex, arrived on time, were very hard working, courteous, and very skilled in all aspects of the job. They were all so pleasant and easy to work with. The floor is beautiful—no more ugly salt damaged concrete! Thanks, Slab Lab!
Highly recommend. I’ve had the floor in my garage for about a year, and it still looks brand new. If I move, I’ll be calling them again for the next garage.
