An 819 sq ft Edmonds garage was coated in Smoke flake Penntek polyurea in January 2026, with a 50°F slab and the crack repaired first.
Most people assume garage floors are a summer project. This Edmonds homeowner didn't wait. Their big three-bay garage, with an open wood-beam ceiling and room for cars plus a workshop corner, had a stained slab with a long crack and a coat of pine needles and grit that never really swept out. They booked the work for the first week of January.
In January 2026 our crew installed a garage floor coating in Edmonds with Certified Penntek polyurea in Smoke flake. 819 square feet, coated in the middle of a Northwest winter.
We ran the free consultation in December 2025. A scratch test checked the hardness of the concrete, and the moisture meter read 4.4% and 4.2%. The slab had a long crack, dark oil shadows and the general wear of a garage that gets used.
On install day the Penntek warranty job card recorded what we were working with:
We log those numbers on every job because they matter. A coating applied too close to the dew point can trap moisture. Here the slab sat above the dew point all day.
Cold weather doesn't rule out a coating. What matters is the slab. We check slab temperature, air temperature, humidity and dew point before anything gets mixed, and we only go ahead when the numbers line up. On this January day they did. Our post on coating concrete in the winter goes into more detail.
The process stayed the same as any other month:
Smoke Evolution is a mid-grey blend with black, white and tan chips. Under the warm wood beams of this garage it reads as a deep, even grey with a little warmth to it. The 1/4 inch flake hides tire marks, sawdust and winter grime well, which is handy in a space this size.
A January install means the floor went straight into winter duty. Wet tires. Road salt from trips over the passes. Mud. The polyaspartic topcoat is non-porous, so none of that soaks in. It also resists hot tire pickup, the problem where warm tires lift a weak coating right off the slab.
The bond is the other half. Penntek polyurea forms a chemical bond with the concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up. See it for yourself in the Penntek Hammer Test.
Edmonds winters are more wet than frozen, but the slabs stay cold and damp for months. That is exactly when a bare garage floor looks its worst. Having a coated floor by January means the mess from the rainy season wipes up instead of soaking in.

Yes. We record slab temperature, air temperature, humidity and dew point on every job and plan around them. This Edmonds floor went down with a 50°F slab and 45°F air.
Salt sits on top of the non-porous polyaspartic topcoat instead of soaking into the concrete. Rinse or mop it off when you get the chance and the floor stays clean.
It takes more material and more grinding, but the steps are the same. We give you a clear schedule for your size of floor at the consultation.
