Picked From Chips on the Driveway: A Woodinville Garage in Tidal Wave

A cluttered Woodinville garage with red paint smears and a crack got Tidal Wave flake polyurea in one day in September 2025, after the owner picked the color from samples.

Tidal Wave flake polyurea floor in a Woodinville garage with open framed walls

When Cascade first stepped into this Woodinville garage, it was the garage most of us have. Ladders, shop vacs, extension cords, bins and boxes covered almost every square foot. Under the clutter, the concrete had smears of old red paint, worn spots and a crack running across one side. The walls were still open framing and OSB. The owner was ready to make it a real room, starting from the floor up.

In September 2025 Cascade installed a garage floor coating in Woodinville with Certified Penntek polyurea in Tidal Wave flake. One day, once the garage was cleared.

The August consult: tests and flake samples

The free consultation was in August 2025. The crew did what they do on every visit.

  • Scratch test for concrete hardness, right next to old paint drips.
  • Moisture readings of 4.0% and 3.4%, one taken right beside the crack.
  • Color samples. Flake sample boards laid out on the driveway in daylight, so the owner could see them next to the house instead of on a screen.

Picking color outside matters. Flake looks different in sun, shade and under garage lights, and seeing it at full size beats a tiny swatch.

Install day

  1. Industrial diamond grinding to remove the red paint smears and open the concrete.
  2. Vacuum, then fill the crack with Penntek Mender crack repair.
  3. Pure polyurea basecoat, over 99% solids.
  4. Full broadcast of Tidal Wave flake, carried a few inches up the walls as a cove.
  5. Scrape and collect the extra chips.
  6. Polyaspartic topcoat with FadeLock™ UV stability.

By the end of the day, the paint, the crack and the patchy gray were all gone under one even floor.

Why Tidal Wave won

Tidal Wave Evolution is a cool mix of white, gray and navy chips. It is a calm color that will work with whatever the walls turn into after the drywall goes up. It also hides sawdust, footprints and the odd paint drip from future projects. If you are still deciding, browse the full lineup on our styles and colors page.

What this floor does that paint and epoxy don't

Those red smears were a reminder of what happens to things sitting on bare concrete. They soak in. Most typical epoxy and paint coatings only stick to the surface, so they wear through or peel, often in years 3–5. Our post on why garage floor coatings peel walks through the usual causes.

A Penntek floor forms a chemical bond with the concrete at over 1,300 PSI, and its polyaspartic topcoat is non-porous. Paint, oil and grease sit on top and wipe off. Hot tires won't lift it either, since the topcoat resists hot tire pickup. The Penntek Stain Test shows how it handles spills.

Unfinished garages in Woodinville

A lot of garages around Woodinville sit somewhere between storage and project space, with framing showing and plans for later. Coating the floor first is a smart order of work. It is the hardest thing to do once cabinets and finished walls are in.

Questions from this job

How do I pick a flake color?

Look at real samples in your own space. Cascade brings flake boards to the free consultation and lays them out in daylight and under your garage lights, so you can see how each blend looks on your concrete.

What happens to old paint spills on the slab?

They get ground off. Diamond grinding takes the top layer of concrete down to a clean, open surface, which removes paint drips and smears before the basecoat goes on.

Can you coat before the garage walls are finished?

Yes. This garage still had open framing and OSB. Doing the floor first means no one has to work around cabinets or protect fresh drywall later.
