Curves, Steps and a Fire Pit Pad: A Snohomish Backyard in Fieldstone

A curved walkway, stepped patio and kidney-shaped fire pit pad in Snohomish, ground down and coated in Fieldstone flake Penntek polyurea in May 2026.

Nothing about this backyard is square. The walkway curves along the house between beds of river rock, the patio steps down in soft arcs past a Japanese maple, and out in the lawn sits a kidney-shaped fire pit pad with a steel ring set in the middle. Curved decorative saw cuts run through all of it. The concrete underneath had a worn tan finish that had gone patchy and dull, with pits and surface damage showing through.

In May 2026 Cascade coated every piece of it, walkway, patio, steps and fire pit pad, with Certified Penntek polyurea in Fieldstone flake. If you are looking for a patio and walkway coating in Snohomish that handles freeform shapes, this is what it looks like done.

Where the concrete started

The free consultation was at the end of March 2026. Moisture readings on the patio came in at 3.4% and 3.5%. Cascade tests every slab before quoting, outdoor concrete included.

The old tan surface had worn through in places, and the steps were stained and weathered. A worn finish like that has to come off before anything new can bond. Once the crew ground it down in May, the pits and damaged spots showed up clearly across the patio and the fire pit pad.

How a freeform backyard gets coated

The work ran over several days in mid-May 2026:

  1. Industrial diamond grind on every slab, removing the worn finish, then vacuum.
  2. Fill pits, low spots and cracks with Penntek Mender repair.
  3. Hand-coat the step risers, slab edges and the curved outer rim of each slab.
  4. Pure polyurea basecoat, over 99% solids, chemically bonded to the concrete.
  5. Full broadcast of Fieldstone flake, scrape and collect.
  6. Polyaspartic topcoat with FadeLock™ UV stability.

The decorative saw cuts were kept, so the curved lines still flow through the finished surface. The fire pit pad was coated around its steel ring.

Fieldstone with tan siding and river rock

Fieldstone Enviroflake is a warm blend of tan, cream and soft brown chips. Next to the tan siding, the cedar deck and the grey river rock, it looks like it belongs in the garden instead of on a garage floor. It also hides the things a backyard collects: pollen, maple leaves, soil from the beds and footprints coming in off the lawn.

Built for sun, rain and the grill

Outdoor concrete gets the full Pacific Northwest treatment: months of rain, frost in winter and direct sun in summer. Typical epoxy does poorly outside because it yellows under UV and is too rigid for a slab that moves. The Penntek basecoat is flexible, and the FadeLock™ topcoat passed a 16-hour QUV accelerated UV test without yellowing.

The topcoat is non-porous, so grill grease, spilled drinks and tree sap stay on top and wash off. The Penntek Stain Test shows how that works. Under it all, the polyurea bonds chemically with the concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up.

Outdoor concrete coatings in Snohomish

Snohomish yards stay wet for much of the year, and shaded concrete greens over fast. A sealed surface sheds water and rinses clean with a hose. Late spring, when this job went in, is a good window for outdoor work. Our post on the best time of year to install a coating here explains the timing.

Freeform patio questions

Can you coat curved or freeform concrete?

Yes. Shape doesn't change the system. Curved edges and round steps take more hand work, which the crew plans for. On this job every curved rim and step riser was coated by hand.

Will my decorative saw cuts still show after coating?

They can. Here the curved saw cuts were kept as clean lines through the Fieldstone flake, so the original design of the patio still reads in the finished surface.

Can a worn old patio finish be coated over?

The old finish gets ground off first. Penntek polyurea needs to bond with clean, open concrete, not with a worn layer sitting on top. Grinding also shows any pits or cracks that need repair.
