How is the concrete polished?
Depending on the aggregate exposure level required, the first three to four passes use a metal bond diamond. The last metal bond grinding step is used in combination with a grouting system to fill hairline cracks and micro air holes in the concrete surface. This provides a smooth polished concrete surface for the next phase of polishing.
After the grouting has been completed, a concrete hardener is applied to the concrete slab to give it the extra strength required for optimal polished concrete results. Unlike other polished concrete applicators, we apply a concrete hardener between three to five times depending on existing concrete strength. This strengthens the concrete and prepares the surface for the resin bond polishing pads.
Once the concrete has been polished to the desired gloss level, we install a penetrating sealer for added protection against staining. The penetrating sealer protects the concrete from foot traffic, chemical spills, oil spills & general staining.
