Epoxy Flooring FAQs, answered by experts

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.

It costs between $600 and $8,400 to stain an average-size concrete patio of around 300 square feet. The wide price range accounts for intricate stains that incorporate multiple colors and stenciling, high-end sealers, and special touches, such as stamping or concrete polishing. Prices can also vary if you need to make multiple repairs to your patio before adding the stain and seal.

Proper surface prep and application techniques by pros minimize peeling, ensuring longevity.

Yes, you can seal an old concrete floor as long as you remove stains and repair damage before sealing. Remove everything from the garage and clear the floor throughout with a concrete cleaner and power washing. Fill in cracks larger than 1/8 of an inch wide and remove all grease and rust stains before sealing. Make sure your concrete is fully dried before applying sealer.

The type of paint you use on concrete influences how long it will last. Epoxy paint can last as long as 30 years and often comes with a warranty for at least 15 years. Another factor impacting the longevity of the paint is how much wear and tear the floors receive, such as heavy machinery or constant foot traffic, which can shorten the life span.
