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 produces 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.
