Frequently Asked Questions

Other FAQs :

• Q: What is the recommended frequency for sealing polished concrete floors?
• A: The recommended frequency for sealing polished concrete floors depends on factors such as the type of sealer used and the amount of foot traffic the floors are exposed to. Australia's Deepshield™ range of deep impregnating water-based sealers, for instance, offers long-term benefits, with Deepshield™ Gold providing protection for up to 15 years. On the other hand, topical sealers typically have a lifespan of around 3 years. However, it is important to note that high foot traffic or severe weather conditions, especially for outdoor concrete, can potentially shorten the lifespan of the sealer. Additionally, the condition of the surface plays a role in determining when resealing is necessary. If you notice patchy areas or the floors are staining easily, it may be a sign that resealing is needed. Feel free to contact us for further assistance and any inquiries you may have regarding sealing your polished concrete floors.
• 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: Does sealing concrete surfaces help prevent efflorescence?
• A: Efflorescence can occur on concrete and other porous surfaces when water in the concrete brings salts to the surface as it evaporates. This process leaves behind a whitish coating that can mar the finish of the concrete. Sealing the concrete with a high-quality, water-resistant sealer can help mitigate efflorescence to some extent. However, it is important to address the underlying issue causing the water penetration, such as a water pipe leak or damaged grout, in order to fully prevent efflorescence. By sealing the concrete and resolving any sources of water infiltration, you can minimize the occurrence of efflorescence and help maintain the aesthetic integrity of your concrete surfaces.
• 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.
