Sealing resurfaced concrete is not an absolute necessity. However, it is recommended, and in most cases, a high-quality concrete sealer can protect the surface from stains as well as water penetration, extending the life of the resurfacing material. Some sealers are formulated to protect pigments from fading due to UV exposure. Sealer tends to enhance the colors in decorative resurfacing applications, making them more vibrant and richer compared to the duller, more faded appearance of concrete colors without sealer.

Epoxy coatings for garage floors offer a variety of finish and design options, including:

• Decorative colored flakes: $10 per 250-pound bag

• Metallic epoxy: $5–$12 per square foot

• Rock or stone epoxy: $100 per gallon

• Acrylic and poly-acrylic sealants: $0.85–$1.15 per square foot

• Polyurethane sealant: $0.95–$1.10 per square foot

• Polyurea sealant: $150 per gallon

Concrete can take years to fully settle, but interior concrete floors are mostly settled after a year. Shifting and settling can occur throughout your home’s life, but most major settling happens the first few years after the concrete is poured. It’s not uncommon for minor cracks to appear in concrete floors over time—check with a concrete pro to ensure new cracks don’t indicate a structural issue in your home.

Resurfacing a garage floor takes about eight hours on average, with another couple hours over three days to do the epoxy. Epoxy goes on in three coats, with each coat taking 24 hours to dry and cure. You’ll need to keep foot and vehicle traffic off of your garage floor for around 4 days in total when replacing your garage floor, so be sure to plan ahead before you start. This is a great time to organize your garage since you’ll need to move everything out to apply the epoxy.
