Concrete by it’s nature is a porous material. In fact, if you examine concrete under a microscope its appearance closely resembles the appearance of a kitchen sponge. For this reason, untreated concrete surfaces are especially prone to staining.

One of the primary goals of concrete polishing is to significantly increase concrete’s resistance to staining. This is achieved by modifying the concrete with two additives. The first additive is a penetrative silicate densifier. Silicate densifiers bond with the lime in the concrete to fill any pores with a cementitious silica mixture. This both eliminates the floor’s porosity as well as significantly strengthens it’s surface, increasing stain resistance. The second additive is a water-based acrylic stain coat. These are non-film forming sealers that soak into the concrete to provide a clear, protective surface. Although these sealers are very durable, concrete sealers should be periodically inspected by a professional and re-applied when needed. Most stains we repair on polished concrete floors are in high traffic areas where the acrylic stain coat has been allowed to wear off.

Do polished concrete floors stain?
Although polished concrete floors are stain resistant, they can still stain if spills are not addressed promptly. The most common stains we see are fruit juice, wine, vinegar, laundry soaps and pet stains. These liquids tend to have an extreme pH, and can etch or dissolve the most superficial surface of a floor, requiring repair.

How do I clean spills on a concrete floor?
With any spills on a polished concrete floor, you should first mop up as much of the spill as possible using a paper towel or rag. Next, clean the entire area with a warm soap and water mixture to dilute and neutralize any remaining residue. If the stain is still noticeable after the floor dries, contact us for a free repair evaluation.

My floor is subject to frequent spills, should I still install polished concrete floors?
In most cases polished concrete floors are still the best compromise between durability, maintenance and appearance. We install and maintain floors in many high spill establishments, such as restaurant dining areas and wedding venues. However, in some very high traffic installations, a film-forming solvent based sealer or epoxy coating might be the ideal solution. Give us a call for a free design consultation
