Frequently Asked Questions

Q: How long does it take for concrete sealer to dry? - Polishing Natural Stone | Polishing Concrete Floors

• A: Most concrete sealers dry fairly quickly and are usually touch-dry after 4 hours. This is true of both penetrating and topical sealers. Penetrating sealers usually fully cure in 24 hours with topical sealers generally taking up to 48 hours to fully dry.

Other FAQs :

• 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.
• 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: What is the optimal timing for sealing concrete, and how can I determine if my concrete surfaces require sealing at the present moment?
• A: The optimal time to seal your concrete is right after installation to provide immediate protection against staining and damage. As for determining if your concrete surfaces require sealing, there are a couple of indicators to look out for. Firstly, if you notice patchy areas on the floor where the sealant has worn off or is uneven, it is a clear sign that resealing is needed. Additionally, if your concrete is becoming more susceptible to staining and is no longer repelling liquids as effectively as before, it is a good indication that it is time to apply a fresh coat of sealer. By addressing these signs promptly, you can ensure that your concrete remains adequately protected and maintains its optimal appearance.
• 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 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.
