A long Snohomish shop with an ATV lift, welder and wide slab cracks got crack repair and a bright Domino flake Penntek polyurea floor in June 2024.
Some garages are really shops. This one in Snohomish is a long, high-ceilinged building with a mini-split on the wall, a ceiling fan, a TV at the far end, a red rolling toolbox, a welder and an ATV up on a lift. The owner spends real time in here. The bare concrete floor was the weak spot: dusty, stained and split by a set of wide cracks running across the middle.
In June 2024 Cascade gave it a shop and garage floor coating in Snohomish with Certified Penntek polyurea in Domino flake. Every crack got filled first. Then the floor went from dusty grey to a bright black-and-white flake that makes the whole building look cleaner.
At the free consultation in June 2024, the meter went down in three spots and read 4.8%, 5.2% and 4.6%. On install day the crew tested again and got 4.0% in two places. That's the routine on every Cascade job: test at the consult, test again before any coating goes down, and decide from the numbers whether the slab needs a two-layer moisture barrier.
The cracks were the bigger story. After grinding, the full pattern showed: long lines branching across the slab, with a few spots wide enough to see the edges of the broken concrete. A slab like that is exactly where rigid coatings fail first.
When the tools and the ATV came back in, the cracks were gone from view.
Domino Evolution is a crisp mix of black, white and grey chips. Under bright shop lights it reads as a light grey that bounces light around the room, and the black chips keep it from looking dirty when there's sawdust, metal shavings or a tire track on it. It also looks right next to a red toolbox, which never hurts.
Cracked concrete keeps moving. It shifts with temperature and with the freeze-thaw cycles we get every winter. Rigid epoxy can't follow that, so it tends to crack right along the old lines, often around years 3–5. The Penntek basecoat is flexible. It moves with the slab instead of fighting it.
The bond matters just as much in a shop. Penntek polyurea bonds chemically with the concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up. Watch what happens when a hammer hits it in the Penntek Hammer Test. The polyaspartic topcoat is non-porous, so oil, grease and gas wipe up instead of soaking in.
Out in the Snohomish valley a lot of homes have a detached shop or an oversized garage. Those buildings often sit on slabs poured years ago, with no vapor barrier and plenty of cracks. Testing moisture before anything else is how you avoid a coating that bubbles or peels a few winters later. Our post on whether moisture in concrete can ruin a garage coating explains why.

Yes. After grinding, each crack is filled with Penntek Mender crack repair, then the flexible polyurea basecoat goes over the whole floor. The basecoat moves with the slab, so repaired cracks stay covered.
Concrete moisture shifts with weather, season and what was sitting on the slab. That's why Cascade tests at the consultation and again right before coating. The install-day number is the one that decides if a moisture barrier goes down.
Where a shop or garage has a low concrete curb or stem wall, the crew can carry the coating up it. It keeps dirt and water from collecting at the edge of the floor and makes the whole room easier to wash out.
