Sealed Garage Floor Coatings That Stand Up to Portland Weather
Winter in Portland means salt spray, freeze-thaw cycles, and vehicles tracking moisture into the garage. A properly prepped epoxy, polyaspartic or metallic coating seals the concrete slab and makes cleanup effortless. We grind every floor to bare concrete first, because that's where durability starts.
When a Garage Floor Coating Fails, It's Almost Always the Prep
A coating applied over a sealed, dusty or glossy slab will bubble and peel within months. The finish cannot bond to a surface it cannot grip. That's why we start every job by grinding or shot-blasting the concrete to open its profile, then testing for moisture and repairing any cracks or spalling.
Once the slab is sound and clean, the coating system goes down in full: primer, body coat with optional flake or metallic, and topcoat. Each layer is applied to manufacturer spec for thickness and cure time. The result is a sealed floor that resists salt, hot tires and freeze-thaw stress.
We test for moisture, identify cracks, pits and old sealers, and determine which coating system fits your use and timeline.
Grind or shot-blast the concrete
Mechanical grinding or shot-blasting opens the slab profile so the coating can bond. We fill cracks and repair pits to create a sound base.
Apply primer, body and topcoat
We apply the full coating system per manufacturer specs, including flake or metallic pigment if chosen, with proper cure time between coats.
Cure, inspect and hand off
The coating cures fully, we walk the floor with you, and we provide care instructions and the timeline for returning to normal use.

Choose the Coating System That Fits Your Garage
Epoxy is the standard choice: tough, sealed, flake-finished and priced for most homeowners. Polyaspartic costs more but cures in roughly a day and resists UV fading better than epoxy, so it's ideal if you need the garage back in service fast.
Metallic epoxy creates a marbled, high-end look without sacrificing durability. If you want no coating at all, a polished garage floor skips the peel risk entirely and delivers a hard, sealed slab. When an old coating has failed, garage floor repair strips it, re-profiles the concrete and rebuilds the system correctly. We also offer stained concrete and self-leveling epoxy for interior spaces.
Coating systems, prep, cost and durability for a Portland garage floor.
Coatings peel when they are applied over an unprepared slab. We mechanically grind or shot-blast every floor to a clean profile and check for moisture first, so the coating bonds to sound concrete instead of dust or old sealer.
Epoxy is the proven, cost-effective workhorse. Polyaspartic costs more but cures in about a day and holds its colour under UV. We match the system to how the garage is used and your timeline.
Yes, when it is the right system on a properly prepped slab. Epoxy, metallic and polyaspartic coatings are built to resist de-icing salt, moisture and hot-tire pickup, which is exactly what a Portland garage throws at a floor.
Coatings generally run $4 to $9 per square foot depending on the system, the slab condition and how much repair the concrete needs first. We confirm it with a written, itemised quote after seeing the floor.
Yes. Garage floor repair strips the failed coating, re-profiles the slab, repairs the concrete and rebuilds the system properly so the new finish actually bonds and lasts.
