Fog sits over the East Fork Lewis River on winter mornings and it does not burn off fast. That dampness gets into the ground and into the concrete in the older part of La Center, where the 1900s to 1970s houses near Sternwheeler Park have detached garages with thin, cracked floors and no vapor barrier. Coating one of those without a moisture test is how you end up with bubbles. So we test first, every time.
Ring the old core and you are in subdivisions from the 2000s to the 2020s, up toward the Timmen Road area and out by the I-5 junction. Those slabs are the opposite problem: fresh, smooth, sometimes still curing, often with builder compound on top. And out toward Lockwood Creek there are shops on acreage. Three different prep plans in a town that takes us about 25 minutes to reach on I-5, exit 16.
Why the Moisture Test Comes First in a River Town
Epoxy fails from underneath, not on top. Water vapor moving up through a slab lifts a coating that was not designed for it, and La Center has more of that vapor than most Clark County towns because of the river and the fog. A calcium-chloride or RH test tells us the number. Under the limit, standard system. Over it, a moisture-mitigating primer goes on first and the standard system goes over that.
The standard system is 100% solids epoxy ground into the slab, flake broadcast until the surface will not accept more, and a polyaspartic topcoat that does not lift under hot tires and lets spilled oil and gas wipe right off. Thirty to 40 mils, ready for foot traffic a day or two after we finish and for vehicles in about a week. The 5-year workmanship warranty covers all of it, and it covers an old detached garage the same as a new subdivision garage as long as we did the prep.
