Grind & Seal

Built for warehouses, shops, storage buildings and other big spaces that don't need a fancy finish, just a floor that's protected and easy to maintain. We grind the slab clean and seal it, stopping dust and stains for much less than a full coating.

How we do it

  1. 01

    Clean & inspect

    We clear the floor, lift oil spots and check for cracks or moisture.

  2. 02

    Diamond grind

    Grinding removes stains, glue and old coatings and exposes fresh concrete. A deeper grind can show more of the stone.

  3. 03

    Fill & smooth

    Cracks and pits are filled, then the floor is refined with finer diamonds for a smooth finish.

  4. 04

    Seal

    A penetrating sealer or clear coat is applied to harden the surface, stop dusting and resist stains.

Why grind & seal

  • Protects the slab without paying for a decorative finish
  • Stops concrete dust from settling on inventory and equipment
  • Resists oil and spill stains, so cleanup is quick
  • Low cost per square foot, even on big buildings
  • Easy upkeep: sweep, scrub or damp mop

Good to know

  • It's a practical finish, not a showpiece. Old repairs and stains may still show a little
  • Want a high-shine look? See polished concrete
  • Heavy chemicals, hot washdowns or forklift traffic? Urethane cement or epoxy may be a better fit
  • Sealers need refreshing from time to time to keep their protection
