CONCRETE GRINDING & POLISHING

CONCRETE GRINDING & POLISHING
Concrete Sealing and Grinding NZ can grind, smooth and level most new or existing floors to expose the composite within until the desired degree of aggregate is achieved.

This involves grinding the concrete and then polishing up to 3000 grit with special bonded diamonds to achieve the desired surface, which is then sealed with one of our special coatings, that produce a hard wearing, low maintenance and fashionable finish.

Concrete Sealing and Grinding NZ can also grind your concrete to remove glue, paint, wax, fiberglass and stains, as well as to repair rain-damaged concrete.

EPOXY COATING SYSTEMS

Concrete Sealing and Grinding NZ is an approved applicator for a variety of epoxy floor coatings. We have epoxy coatings suitable for use on a wide range of floors including garages, mechanical workshops, warehouses, high impact floors, electrostatic safe floors for computer server rooms etc.

The floor surface must be properly prepared using diamond grinding, otherwise the coating (epoxy) will delaminate and break up, flake or peel. The epoxy coating, whether a roll coat system or moisture tolerant epoxy primer, is then bonded to this substrate.

FLOOR LEVELLING & REPAIRS

FLOOR LEVELLING & REPAIRS
Levelling

Self levelling floor preparation is a blend of specially graded fillers, fine cement and polymers, developed as a premium smoothing and levelling compound for internal floors with irregular substrates. It is used to level the sub-floor prior to the application of floor tiles, timber flooring or decorative surface flooring.



Steps for levelling:

The entire floor area is diamond ground to remove the surface layer, high spots and construction debris to ensure the best possible key to the slab.
  • A moisture barrier may be applied to protect the levelling compound from excess moisture in the concrete slab.
  •  specified primer is applied to suit the porosity of the concrete slab.
  • The levelling compound and any appropriate strengthening additives are applied.
  • The sub-floor is now ready for the application of surface flooring.

EXPANSION JOINTS FILLER

Concrete Sealing and Grinding NZ has the experience and expertise when it comes to expansion joint filling. Expansion joints are placed in floors to allow for natural movement as concrete may expand or shrink as it cures. The joints are cut into the floor after the concrete is hard enough to walk on.

CONCRETE SEALING & POLISHING

CONCRETE SEALING & POLISHING
Whether a warehouse, bar, restaurant, shop, kitchen, patio, showroom or some other surface, Concrete Sealing and Grinding NZ can grind, seal and polish your concrete to produce a smooth attractive finish.

Sealing concrete has many advantages. It cures and hardens the surface, prevents concrete dusting and makes the surface more abrasion resistant.

There are two ways to seal a concrete floor:

Spray on Sealers – involves scrubbing the concrete with our ride on scrubber and applying a surface sealer to the concrete. An anti-slip additive can be used in the sealer.
  • Diamond Polished – involves grinding the concrete with metal bonded diamonds and applying an integral sealer that penetrates the concrete and blocks the pores and then hardens. The result is a floor that is very hard and will not allow the penetration or escape of dust.
The sealed surface is then polished with resin bonded diamonds in various grades until the desired finish is obtained.
