Concrete Sealing and Stained Concrete Floors
Concrete Doctor seals concrete across the Denver metro and Front Range, from driveways and patios to interior floors. We also stain and seal interior concrete, so a plain basement or living space slab becomes a finished floor that is easy to clean.
What Is Concrete Sealing?
Penetrating and topical sealers protect Colorado concrete from moisture, stains, de-icing salts and freeze-thaw damage.
Outside, a penetrating sealer soaks into driveways, patios and walkways and keeps water and salt from working into the surface. Inside, and on decorative concrete, a film-forming sealer adds a protective layer that resists stains and makes the floor easier to clean.
Stained Concrete Floors
Stained concrete turns the slab you already have into a finished floor. It works well in basements, living spaces and other rooms that mostly see foot traffic. Because it is indoor work, winter is a good time to book it.
There are two kinds of stain. Acid stain reacts with the lime in cured concrete and etches color into the surface, which gives rich, mottled earth tones. Water-based stain is a pigment that soaks into the surface, which opens up more colors and a more even look. Either way, every slab takes color a little differently, so no two stained floors look exactly alike.
How We Stain and Seal a Floor
First we clean and prep the slab so the stain can soak in evenly. Old sealer, paint and oil all keep stain from taking, so they have to come off first.
On a slab we have not worked on before, we test a small area so you can see how the color develops on your concrete. Then we apply the stain and finish with a sealer. The stain gives the floor its color. The sealer protects it from dirt, moisture and wear and keeps the color from fading.
Is Stain and Seal Right for Your Floor?
Stain and seal is a good fit when you want a warm, finished look without carpet or tile, on a floor that mostly sees foot traffic.
For a garage or shop floor that takes vehicle traffic, hot tires, tools and chemicals, a coating system holds up better than stain and sealer. We will tell you which one fits your floor during the free on-site estimate.
