A Seattle homeowner reclaims their garage with a durable Penntek polyurea coating in medium grey, creating a clean, professional space that stands up to Pacific Northwest weather and daily use for decades to come.

When a Seattle homeowner reached out to Cascade Concrete Coatings, their goal was simple: transform their worn garage floor into a functional, attractive space that could handle everything from wet winter gear to heavy workshop use. The solution? A professionally installed Penntek polyurea coating system in medium grey that delivers both beauty and unmatched durability.
Seattle's unique climate presents special challenges for garage floors. Between constant moisture from rain, temperature fluctuations, and the salt and chemicals tracked in during winter months, traditional epoxy coatings often struggle to maintain their appearance and integrity. That's where polyurea coating systems shine.
Unlike epoxy's mechanical bond, Penntek polyurea forms a chemical bond with the concrete substrate that's virtually indestructible. This means no delamination, no yellowing from UV exposure, and exceptional resistance to the harsh chemicals and moisture that Seattle garages face daily. With a 30-40 year lifespan backed by a lifetime warranty, homeowners avoid the frustration of premature coating failure that's all too common with cheaper alternatives.
As a certified Penntek dealer serving the greater Seattle area, our installation process goes far beyond simply applying coating. We start by scientifically analyzing the concrete's moisture levels, hardness, and condition to determine the ideal system for lasting results. Every crack and imperfection is meticulously repaired, and the surface is professionally prepared using industry-leading equipment.
The medium grey finish chosen for this Seattle project provides the perfect balance—light enough to brighten the space and make cleaning easier, while hiding the inevitable dirt and tire marks that come with daily garage use. The subtle decorative flake adds texture and visual interest without overwhelming the clean, modern aesthetic.
One of the biggest advantages Seattle homeowners appreciate is the one-day installation process. Unlike multi-day epoxy applications that disrupt your routine, our team completes preparation and installation in a single visit, with the floor ready for light foot traffic within hours.
The result is a garage floor that truly transforms how homeowners use their space. The non-porous surface cleans effortlessly—oil, chemicals, and salt wash away without staining. The superior flexibility prevents cracking and chipping even when tools are dropped or heavy equipment is moved. And thanks to Penntek's FadeLock™ technology, the color remains vibrant and true for decades, never yellowing or dulling like traditional coatings.
This Seattle garage now serves as more than just a place to park—it's a clean, professional space the homeowner takes pride in, with the confidence that comes from choosing the best concrete coating available for their investment and Pacific Northwest conditions.
