Frequently Asked Questions

Q: Is polished concrete stainproof? - Concrete | Polishing Natural Stone

• A: No, the floor is not stain proof. It is more stain resistant than a regular concrete floor because the pores in the floor are closed up so tight that it keeps liquids on the surface longer looking for a way to penetrate, allowing for a longer time to respond in getting spills cleaned up. However if a liquid is left long enough on the surface stains may result. We recommend sealing your surface with Deepshield™ impregnating sealer which seals the micro pores of your polished concrete and will last for up to 10 years.

Other FAQs :

• Q: Should I seal my polished concrete?
• A: Concrete surfaces are subject to deterioration and degradation of appearance through traffic, UV rays, moisture, rain, chemicals, and other impurities such as oil, gas, grease, acids and salt. This can easily result in common problems such as cracking, pitting, scaling, spalling, delamination, dusting, discolouration, efflorescence, salt damage, etc. Concrete sealing offers excellent maintenance benefits when quality products are used such as Australia's Deepshield™ deep impregnating sealers.
• Q: Can any concrete floor be polished?
• A: Almost any concrete floor. Floors which are saturated with oil, or are in environments where they will constantly be exposed to acids, are probably not ideal for a polished concrete floor. Whether a new construction or a 100 year old slab, most concrete floors can benefit greatly from the aesthetic, durability, and longevity of polishing.
• Q: How slippery is polished concrete?
• A: Many suspect a highly polished concrete floor would become more slippery-and thus more of a problem. Contrary to common perception, the degree of polish or shine is not directly related to slip resistance. Just because polished concrete is shiny doesn't mean it is slippery. If the right processes are applied both internally and/or externally, testing has shown that polished concrete will meet or exceed Australia/New Zealand standards for slip resistance. (Please bear in mind any floor finish can become slippery when wet.)
• Q: Can you polish existing concrete?
• A: In most cases yes we can. The concrete would have to be in very poor condition not to be able to achieve a polished concrete finish.
• Q: Do you apply sealer to the floor?
• A: Polished concrete on its own is quite stain resistant, but many solutions can seep into the pores to create a stain, or even etch the floor. A sealer will line the pores to keep most stains suspended at the surface of the concrete, not allowing the stain to penetrate the floor and further preventing the likelihood of staining.
