CONCRETE SANDING PERTH

Hawk CFC provide superior concrete sanding services in Perth and throughout Western Australia.

Concrete Sanding is one of several techniques used for concrete surface preparation. Sanding is a viable option when your floor needs to be over-coated with paint, sealer, epoxy resin or another resilient finish. Sanding is performed using drum sanders, rotary sanders, and hand-tool sanders for edging. The sander makes contact with the concrete with either sand-paper discs or sanding-screens with a range of grit sizes to abrade harsher with deeper scratches, or softer with a smoother finish.

CREATING THE CORRECT SURFACE PROFILE

Concrete sanding is ideal when the existing product has good adhesion to the slab and does not need to be completely removed, but rather “keyed” or scratched to promote inter-coat bonding.

If the existing coating or paint is a durable, two-component epoxy or polyurethane and you plan on re-coating with a similarly hard product, then you only need to remove the gloss from the surface and leave micro scratches with a minimum of 120 grit. However, if a clear or a thin coat is being applied over the top, then you must ensure that no part of the coating is removed during sanding. In this case, a consistent finish  with minimal scratching is needed so it does not show through the on the final coats.

BENEFITS OF CONCRETE SANDING

Choosing sanding rather than grinding or shot-blasting does have the benefits of being faster than removing the existing surface and it creates less dust, which means less cleanup and less down time overall. However, concrete sanding is only the appropriate choice under certain circumstances, such as if the existing floor does not need to be completely removed and the re-coating material will naturally bond well with the existing floor. In many cases you will need to consider a more heavy-duty option such as  concrete grinding or shot-blasting to ensure proper adhesion for a long-lasting floor.

WHAT TO CONSIDER

It is important to first assess the quality of the coating that you are sanding. If there are signs of poor preparation or use of a substandard material, then the old coating must be removed completely via concrete grinding. If the previous floor had insufficient surface preparation or was poorly applied, it runs a very high risk of failing and peeling in the future, taking any flooring laid on top along with it.

Preparation of the concrete is just as important as the application of your new flooring because a wrong decision means a high chance the new floor failing and de-laminating. Proper surface preparation results in a permanent bond to the substrate and a long-lasting floor.
