A Seattle Warehouse Room Gets a Silver Creek Floor and Cove Base

Silver Creek flake polyurea floor with cove base in a Seattle warehouse room

Commercial floors have to keep working while the business does. The team at Botanica Seattle had a 380 square foot warehouse room south of downtown with white walls, exposed conduit and bare concrete that was dusty, scuffed and hard to keep clean. They wanted a floor that could be mopped, that didn't shed dust onto stock, and that sealed the joint where floor meets wall.

In December 2025 Cascade installed a commercial concrete coating in Seattle with Certified Penntek polyurea in Silver Creek flake, including a cove base that carries the coating up the walls.

What the slab looked like

The free consultation was in late November 2025. The concrete was solid, rated in great condition on the Penntek warranty job card, with the usual marks of a working room: scuffs, a few patches of old residue and dust in the corners.

Testing came first. The moisture meter read 4.5% and 4.7% at the consult, and 4.7% again on install day. A scratch test checked hardness. Slab and air were both 70°F inside the building.

How the work was scheduled

For a business, timing matters as much as the floor. This one was scheduled around the business over two days.

  1. December 17. Industrial diamond grinding and vacuuming, then prep along the base of every wall for the cove.
  2. December 18. Pure polyurea basecoat over the floor and up the cove, a full broadcast of 1/4 inch Silver Creek flake, scrape and collect, and a polyaspartic topcoat with FadeLock™ UV stability.

The card lists 36 feet of verticals. That is the cove base, a curved transition from floor to wall that leaves no seam for water, dirt or debris to collect in.

Silver Creek in a commercial room

Silver Creek is a darker blend of grey, charcoal and white chips. In a room with white walls and bright overhead lights, it gives a clean, professional look without showing every scuff the way a light floor would. The 1/4 inch flake hides foot traffic and cart marks between cleanings.

What makes this floor right for a business

A commercial room gets carts, dropped boxes and constant foot traffic. A few things matter:

  • Bond. The basecoat chemically bonds to ground concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up.
  • Cleanability. The polyaspartic topcoat is non-porous, so spills, grease and grime don't soak in.
  • Lifespan. Problems with typical epoxy often show in years 3–5. A Penntek floor is built to last 30–40 years.

See how it handles impact in the Penntek Hammer Test. The floor is registered under Penntek's warranty, and Penntek has dealers in 200 markets, so a business is never stuck if one installer is gone.

Commercial floor coatings in Seattle

Seattle's industrial and warehouse districts are full of older slabs that see real work. For those spaces, the questions are different from a home garage: How long is the room offline? Does the floor need a cove? Will it pass a wipe-down? Our post on commercial vs residential floor coatings covers what business owners should ask.

Questions from Seattle business owners

Why carry the coating up the wall in a commercial room?

A cove base is the coating carried up the wall a few inches with a curved transition. It seals the joint between floor and wall, so there's no seam to trap dirt or water. Rooms that get mopped or washed down benefit most.

How long will my space be out of use?

It depends on size and scope. This 380 square foot room with a cove base took two days. We schedule commercial jobs around the business and give you clear times for foot traffic.

Can you coat a warehouse in winter?

Yes. This floor went in the week before Christmas. Inside a building, slab and air temperatures are usually steady. This one read 70°F for both.
