Why polishable concrete overlays?
Pitting. Pop-outs. Scaling. Spalling. Excess cracking. Delamination. Patching all over the place. Those in the concrete business are all too familiar with these concrete problems. While concrete is a fabulous building material, it is not without its flaws. Years and years of foot traffic, impact, and abrasion can really take their toll on a slab. It can only take so much before these surface issues arise. Say a retail floor owner desires a polished concrete floor, but the existing substrate is patched and repaired beyond desirable aesthetics. Experienced polishers know those results won't match the owner's expectations. What other recourse does the floor owner have if they want a highly-refined surface?
Enter polishable concrete overlays. Cementitious overlays are designed to top these concrete problems after they've been addressed. A seasoned concrete polisher knows when an existing substrate is not a good candidate for polishing. A proficient polisher also knows that he can give the floor owner options, one of those being polishable overlays.
How do cementitious overlays work?
These cementitious materials are mixed like regular concrete. They feature extended working time, high compressive strength, and may be polished 24 hours after placement. Concrete contractors love them because of their working time and ease of use. Owners love them for their refined, aesthetically pleasing look, not to mention they're durable and easy to clean. In applications where there are multiple locations, such as in retail, polishing contractors can deliver a consistent look and feel for all store locations.
