A covered walkway and porch along a Mountlake Terrace home got a Fieldstone flake Penntek polyurea coating in February 2026 that sheds rain and wipes clean.
Garages get most of the attention, but the concrete people actually walk on every day is often outside the front door. This Mountlake Terrace home has a long covered walkway that runs along the upper level, past sliding doors and a front entry, with a railing on one side and a stair down to the yard. The bare concrete was grey, scuffed and marked with stains, and it stayed damp for most of the winter.
In February 2026 our crew coated the walkway and porch with Certified Penntek polyurea in Fieldstone flake. It is now a warm, finished surface that sheds rain and wipes clean.
We came out for the free consultation in January 2026. The scratch test showed a hard, well-finished concrete surface. The moisture meter read 2.8%. Even under a roof, exterior concrete takes in a lot of water here, so we test outdoor slabs just like garages.
The walkway had foot-traffic wear near the doors, a few drip and rust stains and a control joint across the width. The edges met painted siding and a wood railing, which meant careful masking.
The work ran over two days in early February 2026, with the stair opening taped off so nobody wandered onto fresh coating.
The control joint was carried through as a clean line. You can read more about this kind of project on our walkway coatings page.
Fieldstone Enviroflake is a warm blend of tan, brown, grey and cream. On a walkway next to cream siding and a white railing, it looks like it belongs to the house, not like a garage floor that wandered outside. It also hides what walkways collect: dirt off shoes, pollen, fir needles and dried rain spots.
Even a covered walkway gets daylight, and low winter sun reaches right under the roof. Typical epoxy yellows or ambers in UV. The Penntek topcoat uses FadeLock™ UV stability and passed a 16-hour QUV accelerated UV test, and the flake itself is UV stable.
Outdoor slabs also move more with temperature. The flexible polyurea basecoat moves with the concrete through freeze-thaw instead of cracking. See it in the Penntek Stretch Test. Our post on coating patios, basements and more covers where else this system works.
Mountlake Terrace sits on the hills between Shoreline and Edmonds, and it gets the same long, wet winters as the rest of the area. Covered walkways stay damp, grow a film of grime and get slick with wet leaves. A sealed, textured surface is easier to keep clean and nicer to come home to.
See our concrete coatings in nearby Edmonds, or check out a Mountlake Terrace tandem garage we coated in Tidal Wave.
Yes. We use the same Certified Penntek polyurea system as a garage, with a UV-stable topcoat that won't yellow. Covered and uncovered concrete can both be coated after testing.
The full flake broadcast adds texture to the surface, which gives more grip than smooth paint. Like any outdoor surface, standing water and wet leaves should be cleared. We do not publish slip ratings.
Under a roof, often yes. We check slab temperature, moisture and dew point before we start and only coat when conditions are right.
