Grind & Seal Concrete Floors
GRIND & SEAL — AFFORDABLE POLISHED CONCRETE ALTERNATIVE
Grind and seal is a cost-effective alternative to full mechanical polishing. We grind the concrete surface with diamond tooling to the desired exposure level (cream, salt-and-pepper, or full aggregate), then apply a high-performance topical sealer in satin or gloss sheen. The result is an attractive, easy-to-clean floor at a lower cost than full polishing. Ideal for basements, garages, workshops, and light commercial spaces.
Starting at $3 per sq ft

FAQs About Grind & Seal Concrete Floors
Grind and seal vs polished — what's the difference?
Full polishing creates a mechanical shine by progressively refining the concrete itself — no topical coating. Grind and seal creates the shine with a topical sealer applied over ground concrete. Polished lasts longer without recoating but costs more. Grind and seal requires periodic resealing (every 3-5 years) but has a lower upfront cost.
