Seattle Commercial Floor Coating at Hilltop House

Big rooms show every flaw in a floor. At Hilltop House in Seattle, a large community room with tall windows, wood-framed French doors and a garden outside had an old stained concrete floor in a burnt orange color, scored into squares. The finish was worn through in the walkways, the sealer was peeling at the base of the walls, and the color made a bright room feel dated.

In October 2025 Cascade replaced that look with a commercial floor coating in Seattle: Certified Penntek polyurea in Driftwood flake, from wall to wall across the whole room.

What the old floor was doing

The free consultation was in February 2025. At the time the room was set up with tables, chairs, a kitchen counter and exercise equipment. The old stained finish had a few problems:

Worn and faded traffic lanes where people walk every day.
Peeling sealer and gaps where the floor met the walls.
Saw-cut control joints in a grid across the slab, each one a line where dirt collects.

Cascade tested the slab for moisture and hardness at the consult, as on every job. The months between the consult and the install gave the building time to plan around the work.

Two days, planned around the building

A room this size takes more than a day. The work was scheduled around the building over two days in late October 2025.

Day one. The room was cleared. Industrial diamond grinding took the old stain and sealer off and opened the concrete, followed by vacuuming. The basecoat and flake went down in sections.
Day two. The rest of the basecoat and Driftwood flake broadcast, scraping and collecting the loose flake, and a polyaspartic topcoat with FadeLock™ UV stability across the full room.

The pure polyurea basecoat, over 99% solids, fills in over the old grid, so the floor reads as one continuous surface.

Driftwood in a sunny room

Driftwood is a warm blend of tan, cream, grey and a few black chips. It suits the honey-toned wood doors and window frames and keeps the room light without going stark white. With full sun through the windows, the FadeLock™ topcoat matters. It won't yellow or amber, and the flake is UV stable too.

What a shared space needs from a floor

A community room sees chairs sliding, carts rolling, spills from the kitchen and people walking all day. The things that matter most here:

Easy cleaning. The polyaspartic topcoat is non-porous. Coffee, food and tracked-in dirt sit on top and mop away.
Bond. The basecoat chemically bonds to ground concrete at over 1,300 PSI. Before the coating comes up, the concrete will come up.
Flexibility. A slab cut into a grid moves at its joints. The Penntek basecoat moves with the slab instead of cracking, as the Penntek Stretch Test shows.

The floor is registered with Penntek, and Penntek has dealers in 200 markets, so the building's floor can be serviced long term.

Commercial floor coatings on Seattle's hills

Older Seattle buildings often have interior slabs that were stained or sealed years ago and never refreshed. Those finishes wear through in the busiest paths. Grinding them off and coating gives a building a new floor without tearing anything out.

Facility manager questions

Can you coat over an old stained concrete floor?

We grind the old stain and sealer off first. The new system has to bond to bare concrete, so anything sitting on top of the slab comes off before the basecoat goes down.

Is a flake floor slippery when it's wet?

The flake broadcast gives the surface texture underfoot. As with any smooth floor, wipe up spills promptly. Our post on whether coated floors are slippery explains what affects traction.
