A 390 sq ft Seattle garage with a glass panel door, coated in solid Olympus White Certified Penntek polyurea with aluminum oxide for texture.
Flake is the usual pick for a garage floor. This one isn't. The homeowner had a newer Seattle garage with clean lines: a black-framed glass panel door, white walls, recessed lights and a wall-mounted tankless water heater. A speckled floor would have looked busy. What fit was a solid, bright white.
In spring 2025 Cascade installed a solid color garage floor coating in Seattle using Certified Penntek polyurea in Olympus White, with aluminum oxide in the finish for texture underfoot.
The free consultation was in February 2025. The slab was in good shape for a garage that had been lived in. A few hairline cracks, tire marks, and the usual dust and clutter of bikes, tools and boxes.
The crew tested it like any other job. The moisture meter read 4.7% in one spot and 5.1% in another. A scratch test next to one of the cracks checked hardness. A second visit later that month took measurements around the drain grates and wall edges so the plan for the edges was set before install.
The Penntek warranty job card records 390 square feet of garage, the concrete in good condition, and 55°F air on install day.
A solid floor skips the flake, so every step underneath has to be right. Nothing hides a bad grind. The crew ground the slab at the end of March and finished the coating on April 1.
White makes a garage feel like part of the house. It reflects the overhead lights, so the space reads brighter at night, and it matches the white walls and trim instead of contrasting with them. With FadeLock™ in the topcoat, the color won't yellow or amber over time, which matters more on a white floor than on any other.
The trade-off is honest: a solid white floor shows dirt sooner than a flake floor does. The good news is that the non-porous topcoat makes it easy to clean. Our post on cleaning and maintaining a polyurea floor covers the routine. You can see solid colors next to flake blends on our styles and colors page.
Typical epoxy tends to amber and yellow with UV exposure, and on a white floor that shows fast. Penntek's FadeLock™ topcoat passed a 16-hour QUV accelerated UV test without yellowing. Our post on UV and garage floors in Seattle explains why even a cloudy city sees enough sun through a glass door to matter.
Under the color, the basecoat chemically bonds to the ground concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up. The Penntek Stain Test shows how the surface handles spills. The floor is registered under Penntek's limited lifetime warranty.
Newer Seattle homes with modern garage doors and minimal finishes are a natural fit for a solid color. Older garages with more wear usually do better with flake, which hides imperfections. Either way, the test and prep are the same.
See our Seattle garage floor coating page, compare this with a nearby Seattle garage we coated in Fieldstone flake, or look at a Seattle garage that became a home office.
It shows dirt sooner than a flake floor. The polyaspartic topcoat is non-porous, so a sweep or a damp mop cleans it up. If low maintenance is the priority, a light flake blend is a good middle ground.
Aluminum oxide is a fine grit mixed into the finish. It adds texture to a smooth solid color floor, which otherwise has no flake to give it any.
The Penntek topcoat uses FadeLock™ UV stability and won't yellow or amber. It passed a 16-hour QUV accelerated UV test.
