Concrete Sealing & Coating

Referred to as a GRIND AND SEAL, concrete sealing is a topical coating solution – you get the look of a polished concrete floor without the cost.

Concrete sealing comes in many different forms. We seal the concrete to stop hydrostatic pressure, waterproofing and to give a dust-free surface for garages, workshops, retail, outside decking and the likes.

NZ Grinders use a variety of concrete sealers from water base to solvent. Sealers range from natural which means the concrete has no colour added to sealers that have matt or gloss (wet look).

We use an industrial range that does not yellow from the U.V. and bite into the concrete. We never see any delamination issues. We have sealers for exposed aggregate concrete and normal brushed concrete that help reduce efflorescence.

We do sealing with anti-slip and semi topical coatings to give protection from the elements.

The disadvantage of a topical coat is that it could yellow over time, and the surface needs extra care over its lifetime – it may show scratching from pet claws or furniture movement.

NZ Grinders staff has been trained and approved as Certified Contractors for the HTC Superfloor and Hiperfloor systems.
