Epoxy Floor Systems Built for Portland Warehouses and Plants
Epoxy flooring in Portland starts with the slab, not the topcoat. We assess the concrete substrate, specify a system matched to your chemical and traffic loads, prep the slab to manufacturer spec, and install primer, body coat, aggregate and topcoat as an integrated system. Free written estimate on every project.
Most commercial epoxy failures trace back to one overlooked step: the concrete slab was never properly prepared. A coating applied over a contaminated, uneven, or moisture-saturated substrate will separate from the concrete within months, regardless of epoxy quality. The foundation is the work; the epoxy is the finish.
Our process begins with diamond grinding the slab to the system manufacturer's profile, removing old coatings, contaminants and surface laitance. We test for moisture vapor transmission and apply a moisture-blocking primer where needed. Cracks and joints are filled with compatible material. Only then do we apply the primer, body coat with broadcast aggregate where slip resistance is required, and topcoat in the correct sequence with proper cure time between each layer.
How Portland Concrete Installs Epoxy Floor Systems
Assess and specify
We evaluate the slab condition, understand the intended use (wash-down, chemical exposure, vehicle traffic, slip requirements), and specify the epoxy system, primer, body coat, aggregate and topcoat that will perform in that environment.
Grind and prepare
Diamond grinding removes old coatings and surface contaminants, bringing the slab to the system's prep profile. Moisture testing determines if a vapor-mitigation primer is needed. Cracks and joints are filled with compatible filler material.
Prime and build
The primer bonds the epoxy to the concrete. The body coat is applied at the specified thickness. Slip-resistant aggregate is broadcast into the wet body coat where required by the specification.
Seal and return to service
The topcoat seals the system and provides the wear surface. The floor cures according to the manufacturer's schedule. We provide a clear timeline for foot traffic, vehicle traffic, and chemical exposure so you can plan operations accordingly.
System selection matters
Choosing the Right Epoxy Specification Extends Floor Life
Commercial epoxy systems differ significantly in chemical resistance, abrasion rating, temperature tolerance and slip classification. A system specified for light office traffic will fail in a wash-down kitchen or service bay. We specify based on the actual environment and use, not the lowest-cost option that fits the budget.
When the epoxy install is part of a larger renovation, we coordinate with adjacent polished concrete in office zones and loading dock concrete outside the building so all floor systems transition cleanly and perform as a unified whole.
Slab prep, chemical resistance, slip ratings and what makes commercial epoxy worth specifying.
A properly specified and installed system lasts the better part of a decade or longer in most commercial environments. Wear comes from traffic and chemicals; the system spec determines how it handles each. We size the spec to your use.
Diamond grinding to the manufacturer's prep profile is our standard, removing contaminants, old coatings and surface laitance. Where moisture testing flags a high-vapor slab, a moisture-mitigation primer goes on first. Skipping prep is why coatings fail.
Yes, with the right system spec. Wash-down floors get a system with chemical resistance and slip aggregate; food processing gets a system rated to that environment; service garages get a system rated for hot tires and automotive fluids. The system matches the use.
Foot traffic typically a day after the topcoat; full vehicle or chemical service later in the cure schedule. We give you a clear return-to-service timeline before the install so you can plan production around it.
Sometimes, but usually we remove the failed system back to clean concrete first. Installing over a failing layer just inherits its failure mode. The honest scope often includes removal as a line item; the quote tells you up front.
Client reviews
What Portland Operations Say About Their Commercial Epoxy Floors
Three contractors quoted slab prep as a paint roller and a primer. Portland Concrete quoted diamond grinding and explained why. Two years in, floor is still tight to the slab, no peeling.

★★★★★
Service-bay system rated for hot tires and automotive fluids. Wash-down works, no spalling at the floor drains, and the slip aggregate is doing its job in winter.

Service Garage Owner, Vancouver
★★★★★
They specced the system to the actual chemical exposure in our plant, not the cheapest option that fits the budget. Worth every dollar; the previous floor had failed in 14 months.
X. U.
Manufacturing Plant Manager, Hillsboro
★★★★★
Coordinated install around our shift schedule. Floor was returned to service at the timelines they quoted, no surprises, no slipped delivery dates. Real professionals.
