Commercial Polished Concrete for Office building

Main Contractor: Walls
Architect: Mola Architecture

500 M2 of concrete polished over 4 floors to a silver finish. Concrete is ground to reveal aggregate then polished up to a 200 grit. This leaves the floor with a satin finish. Floors coated in an anti-slip coating in lobby areas.

Silver Finish

First step is a deep grind which reveals the variations in sand, gravel and aggregate underneath the sandy layer. Giving a Terrazzo like look. Hardener is then applied. After the first grind, progressively smaller diamond disks are used to remove the scratches made by the previous grind. Floor is treated with an impregnating seal after the final grind. The silver finish is left with a matte or satin look.

Easy maintenance, even with heavy use

The easy maintenance of polished concrete is key in high-traffic areas where trolleys are used – such as airports, hotels, supermarkets and warehouses – eliminating the need for waxes. Non-allergic properties are important for hospitals, private residences, schools, etc.

Its glossy surface resists the marks of forklift truck tyres and staining from chemicals and oil on industrial floors. This versatility and toughness makes the concrete an ideal and ultimate flooring material for most floor applications.

Maintaining the shine requires only minimal effort. Just clean the floor regularly with a damp mop to remove grit, and use a suitable cleaner to enhance the shine. With basic cleaning, the floor will keep its lustre for years.

In high-traffic areas, sometimes buffing the floor with a floor pad will be required. Should more intervention be required, the floor can be lightly re-polished after a couple of years.
