Grind and Seal Concrete Floors in New Jersey
Professional diamond grinding and sealing for residential, commercial, and industrial concrete floors. The most cost-effective way to transform your concrete.
What Is Grind and Seal Concrete?
Grind and seal is a concrete floor finishing process that uses diamond grinding equipment to smooth and refine the concrete surface, followed by the application of a protective sealer. It costs $3–$6 per square foot, takes 1–2 days to install, and creates a clean, modern look for basements, garages, retail spaces, and light commercial facilities. The Concrete Makeover has been grinding and sealing concrete floors across New Jersey for over 15 years.
"Grind and seal is the best-kept secret in concrete finishing. For a fraction of the cost of polished concrete or epoxy, you get a beautiful, durable floor that looks like a million bucks. I recommend it to homeowners and business owners who want a clean, modern look without breaking the bank."— Alessio Trabelsi, Owner, The Concrete Makeover

We apply high-performance acrylic, polyurethane, or epoxy sealers depending on your application. Each sealer is selected for UV stability, chemical resistance, and the desired sheen level.

How We Grind and Seal Your Floor

All cracks and spalls are filled with semi-rigid epoxy or polyurea fillers. Control joints are cleaned and prepped.
Diamond Grinding
Progressive diamond grinding from coarse to fine grits. The level of aggregate exposure is customized to your preference — from a light cream finish to full aggregate exposure.
Surface Cleaning
Industrial vacuuming and cleaning to remove all dust and debris. The surface must be perfectly clean for sealer adhesion.
