Frequently Asked Questions

Q: Can I use polished concrete outdoors? - Polishing Natural Stone | Polishing Concrete Floors

• A: A matte (up to 100 grit) or even low sheen (400 grit) can be used outdoors, but polished concrete with a high sheen is not recommended.

Other FAQs :

• Q: Can we just use plain water to clean the floors?
• A: Yes, however it is always best to use a pH neutral cleaner to suspend the dirt so it can be cleaned off the floor instead of just spread around on the floor and leaving a hazy film on the surface.
• Q: Is it possible to apply penetrating concrete sealers over existing topical sealers?
• A: No, it is not possible to apply penetrating concrete sealers over existing topical sealers. Topical sealers create a membrane or film on the surface of the concrete, forming a barrier that prevents the penetrating sealers from effectively absorbing into the concrete. Therefore, before applying a penetrating sealer, it is necessary to remove any existing topical sealer to ensure proper penetration and adhesion of the new sealer. This preparation step ensures that the penetrating sealer can effectively provide the desired protection and enhance the durability of the concrete surface.
• 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: Will you be able to pour the concrete slab?
• A: No, we specialize in the polishing or grinding of the concrete, however we do have concreters that we work with and can recommend to you.
• 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.
