In short

Sealing protects concrete from stains, water and salt. Penetrating sealers soak in and stay invisible; film-forming sealers (acrylic, polyurethane, epoxy) add colour depth and sheen but can be slippery without an anti-slip additive.

What concrete sealing & waterproofing involves

  1. Clean, degrease and let the concrete dry
  2. Repair cracks and joints
  3. Apply the chosen sealer in thin coats
  4. Add anti-slip grit where people walk when wet
  5. Keep traffic off until cured

Common questions

How often should concrete be resealed?

Film-forming sealers on driveways are commonly redone every few years; penetrating sealers last longer. Follow the product's guidance.

Does sealing make concrete slippery?

Gloss sealers can. Ask for an anti-slip additive on outdoor areas.

Can I seal exposed aggregate myself?

Yes, with the right product and preparation, but uneven application and trapped moisture cause white, cloudy patches.
