WHAT WE OFFER

TYPES OF BASEMENT FLOOR COATINGS

Every basement is used differently, storage, a home gym, a rec room, which is why we offer multiple coating systems, each customizable for moisture resistance, color, and finish. Not sure which one's right for you? We'll walk you through the options and recommend the best fit.

HOW IT WORKS

DIAMONDGUARD™️
FLAKE FLOOR SYSTEM

As a family-run team, we don’t cut corners on prep or materials, because a basement floor installed right stays low-maintenance for the long haul. No waxing, no resealing, just a quick sweep or mop when it needs it.

Decorative flakes broadcast into the wet basecoat for color, texture, and visual depth, helping the space feel finished rather than like a utility room.

The tinted coating applied directly over the prepared concrete, bonding to the slab and anchoring the flake layer.

The texture created during grinding or prep, including moisture testing specific to below-grade slabs, ensuring the coating bonds properly and doesn’t trap vapor underneath.

HIGH QUALITY,
LOW MAINTENANCE

As a family-run team, we don't cut corners on prep or materials, because a patio coating built for Oregon's weather stays low-maintenance for the long haul. No resealing, no repainting, just an occasional hose-off or sweep.

BASEMENT FLOOR COATING

FREQUENTLY ASKED QUESTIONS

Most basements are completed in a single day, so you can typically walk on the floor within 24 hours, depending on the system installed.
Pricing depends on the system you choose and your basement’s square footage. Grind & Seal starts around $4.50/sq ft, Solid Color and Flake Systems range from $5.50–$7.50/sq ft, and Metallic finishes run $14–$16/sq ft. Use our instant estimate calculator above for a ballpark, or contact us for an exact quote.
Not necessarily; this is exactly why we test for moisture vapor before every basement install. If moisture levels are high, we can address it during prep rather than skip the project altogether. We’ll walk you through what we find during your consultation.
A sealed, coated floor can help reduce moisture-related odors coming up through bare concrete, though persistent musty smells are sometimes tied to broader moisture or ventilation issues in the space that go beyond the floor itself.
Solid color epoxy gives a clean, single-tone finish, ideal for storage or utility basements. Flake systems add texture and depth for a more finished look. Metallic epoxy uses swirled pigments for a designer look, best suited for basements used as living or entertaining space.
When properly installed on a prepped, moisture-tested slab, our coatings are built to resist cracking and peeling for the life of your warranty. Most failures in DIY or lower-quality jobs come from skipping proper moisture testing, especially important below grade.
Just clear the space of storage, furniture, and any floor-mounted items before your scheduled install date. We handle grinding, repairs, and moisture testing.
Sweep or dust mop regularly, and clean spills as they happen. For deeper cleaning, a mild soap and water mop is usually all you need, no special sealers or waxes required.
In most cases, yes. Minor cracks are repaired as part of our prep process, and we coat around fixed features like sump pump covers and floor drains while maintaining their function.

We back our installations with a lifetime warranty against peeling and delamination when properly maintained.

Yes, we do. Contact us for specific financing options.
