Concrete Coatings in Richland, Washington

Garage floor coatings for Richland’s hot, dry summers and sharp winter nights

Richland sits on the dry side of Washington. At the Tri-Cities Airport weather station in nearby Pasco, NOAA’s 1991–2020 normals show a July average high of 92.5°F and only about 7.6 inches of precipitation a year. That means a lot of sun on driveways, aprons and garage slabs, and very little rain to wash anything off. With 1,700+ floors installed across the region, we plan every Richland job around that kind of exposure.

Freeze and thaw on a Richland slab. Concrete is full of tiny pores, and in winter they take on water. When that water freezes it expands, when it thaws it drains away, and the next night starts the cycle again. NOAA’s 1991–2020 normals for the Tri-Cities Airport count about 112 days a year with a low at or below 32°F, but only about 14 days when the high stays at or below 32°F. That leaves roughly 98 days when a slab freezes overnight and thaws by afternoon, which is how hairline cracks open and surfaces start to flake. A Penntek polyaspartic system seals the floor once the repairs are made, and our residential floors carry a lifetime warranty.

Sun, heat and dust on the slab

A garage door that faces south or west lets the afternoon sun onto the slab for hours. Hot tires, spilled fluids and years of UV are all hard on bare concrete. Our clear coat is a UV-resistant polyurea/polyaspartic topcoat, chosen for sun exposure, and the flake layer under it hides tire marks and dust. The National Park Service records that early Richland residents remembered frequent windstorms blowing dust into poorly sealed homes, and dust is still part of life on this dry side of the state, so a floor you can sweep and rinse matters.

Older homes, older slabs

Much of central Richland was built as Manhattan Project housing. The National Park Service says the “Alphabet houses” designed by architect Gustav Pehrson, more than 4,300 of them built by early 1945, still make up the bulk of many neighborhoods in the heart of Richland, though few remain in original condition. Standard features of those homes included basements. If your home is that age, the garage slab may be older than the house around it, so we do not guess. At the free in-home estimate we check concrete hardness, moisture content and crack or spall repairs, then put the results in writing.

Winter nights below freezing

The same airport station shows normal January lows around 28°F, and Richland concrete still cycles across freezing on cold nights. Water in a crack expands when it freezes, so open joints and hairline cracks are worth sealing before they spread. We fill and mend them during prep, and the finished flake floor gives you one continuous surface to keep clean through the winter.
