Basement Floor Coatings

A sealed, easy-to-clean floor for below-grade space, with the moisture testing that basements specifically need before anything goes down.

  • Moisture-vapor barrier as the first coat, which basements need most
  • Slab moisture read before we quote, not after the coating lifts
  • Seals the concrete so the space smells less like a basement
  • Reflects light, which makes a big difference in a low-light room
  • Holds up under gym equipment, storage shelving, and laundry

Commonly used for: Finished basements, Utility rooms, Basement gyms

The moisture-vapor barrier going down around a water heater and furnace. Below grade, this first coat is the one that matters most.

What to Expect

A basement slab sits below ground, so it pushes moisture up from underneath, and that is what lifts most failed basement floors. We check the slab for moisture before we quote, and the first coat that goes down is always a moisture-vapor barrier. In a basement that is not an extra, it is the reason the floor stays put.

Every one of these is built the same way: grind the slab back to bare concrete, lay a moisture-vapor barrier, then the epoxy base coat, then a polyaspartic topcoat over the top. More on how we build a floor.

Finishes That Suit It

Chip Flake

Color flakes broadcast into the wet base coat, then sealed under a clear topcoat. Hides dust, tire marks, and small debris better than anything else we install.

Solid Color

One even color across the whole slab, no flake or texture. Clean and simple, and usually the most affordable way to get a sealed floor.

Metallic

Metallic pigments swirled into the resin for a marbled, almost three-dimensional look. No two floors come out the same.

Questions About Basement Floor Coatings

What if water has come into the basement before?

Tell us at the estimate. The moisture-vapor barrier handles moisture moving up through the slab as vapor, but no floor coating can stop liquid water coming in through a wall or a crack. If there is active leaking, it needs to be fixed first, and we will say so rather than coat over it.

Can you coat a basement that is already finished?

Yes, as long as the floor can be cleared. We grind wall to wall, so furniture and shelving have to come out, and any carpet or flooring over the slab has to come up before we start.
