A garage on Bull Mountain, a garage in Metzger, and a garage at River Terrace are three different jobs. We do all three.
Free In-Home EstimateStart with the hill. Bull Mountain garages from the 1990s and 2000s follow the slope, so a lot of them are stepped or pitched toward a drain, with a cold joint where the pours meet. Down the hill in Metzger and Summerlake, the 1970s to 90s slabs are flat but 40 years old, with the cracks and old paint that come with that. Out at River Terrace, the slabs were poured in the last few years and are still drying.
We are about 40 minutes south on I-5, which is far enough that we book Tigard as two dedicated days and close enough that the estimate is a normal afternoon trip. Tim brings the moisture meter and the sample boards. The meter matters here because the Tualatin River keeps the low neighborhoods near Cook Park damp, and a slab that reads high needs a different first coat.
Every one of these slabs gets diamond ground or shot blasted, and none of them get acid etched. On a Metzger floor the grind removes paint and opens 40-year-old concrete. On a River Terrace floor it removes curing compound that would otherwise block the bond. On a Bull Mountain floor it evens out the surface around the joints. Then a calcium-chloride or RH reading tells us whether the base coat is standard 100% solids epoxy or a moisture-mitigating primer followed by that epoxy.
The rest of the system does not change: flake broadcast to refusal, then a polyaspartic topcoat that takes hot tires, oil, and road salt in stride. Thirty to 40 mils thick, walkable a day or two after the last coat, with parking about a week out. Bull Mountain gets a bit more wind and rain than the flats, which slows winter cure a little; we lay the topcoat when the afternoon is warmest and warn you the park time may run long.

Hot-tire pickup resistant. Chemical and impact rated.
On Bull Mountain we handle the slope by applying the epoxy at a controlled thickness so it stays put, filling the cold joints with flexible polyurea, and keeping any drain open. At River Terrace the work is removing curing compound and testing moisture, and a mitigating primer goes on most slabs under three years old. In Metzger, Greenburg, and around Summerlake Park the slabs are the oldest in town, so it is paint removal, polyurea, and a moisture test. The low ground near the Tualatin River and Cook Park reads wettest. Forty minutes on I-5 means grind and base coat one day and topcoat the next, with no half-days.

Every slab is different, so we price each floor after a free in-person inspection. A moisture primer at River Terrace or heavy paint removal in Metzger moves the number up. Slab condition, old coatings, cracks, moisture and size are what move the price, and exact pricing comes after that inspection, with a written quote.
Inside the coating
Every floor starts with a properly prepared slab and is built up one layer at a time, each with a specific job.
For concrete floors
No. We apply 100% solids epoxy with a squeegee and back-roll at a set thickness, and it is viscous enough to stay in place on a garage pitch. The drain stays clear and the slope keeps doing its job. The flake and topcoat go on the same way.
Possibly. Concrete that young often still reads high on a moisture probe, and it almost certainly has curing compound on top. We take the compound off no matter what, by diamond grinding or dustless shot blasting, picked for the space. If moisture is over the limit, a mitigating primer under the epoxy makes it workable now rather than in two years.
A few hours of grinding. Old paint has to come off completely because epoxy bonded to paint fails with the paint. We take it to bare concrete by diamond grinding or dustless shot blasting, picked for the space, fill the cracks with polyurea, and check moisture since 1970s slabs may lack a vapor barrier. Once coated, nobody can tell it from a new slab.
It keeps the ground wet. Slabs in the low neighborhoods near the river read higher on the moisture meter than slabs up on Bull Mountain. A high reading means a moisture-mitigating primer before the flake system. We test every Tigard slab rather than assuming based on the address.
In person. We need to meter the slab, look at the joints and drains, and show you sample boards in your own garage light. Estimates are grouped with other south-side visits, and the install is two dedicated days on site.
