Other FAQs :

• Q: How do I know when my stone surface is ready for cleaning, stripping and resealing?
• A: You will know it's time to have your stone stripped, cleaned and sealed once it begins to appear dull or "matte" even after you have given it an efficient regular clean. If you notice that your surfaces are staining easily, it's a good indication that your previous sealer is wearing off and your stone will need to be resealed immediately to prevent permanent staining.
• Q: Why do I need to strip my stone surfaces?
• A: If you want your stone to be its cleanest and looking its very best you need to have a professional remove as much of the old sealer as possible. Once this is done the cleaning process will be carried out and the new sealer applied. You will have the freshest and cleanest possible stone surfaces once we are finished with the process.
• Q: What are the benefits of hiring a professional to seal my stone?
• A: Hiring a professional to seal your stone brings several advantages. Firstly, professionals have the expertise to select the appropriate sealer based on the type of stone and its specific needs. They ensure that the stone is thoroughly cleaned before sealing, removing any dirt or blemishes that could be trapped beneath the sealer. This ensures a clean and flawless surface for optimal sealing results. Professionals are knowledgeable about industry standards and best practices, ensuring that the sealing process is done correctly and effectively. By relying on a professional, you can have peace of mind knowing that your stone will be sealed properly, enhancing its appearance and providing long-lasting protection.
• Q: How often should I seal my stone?
• A: It depends on the type of sealer used and the amount of foot traffic the stone is being exposed to. Australia's Deepshield™ range of deep impregnating water based sealer's offer long term benefits with Deepshield™ Gold lasting up to 15 years. Topical sealer's have a life expectancy of around 3 years. If you have a high amount of foot traffic or perhaps severe weather conditions you may experience a shorter lifetime. Sealing your stone can also depend on the surfaces condition. Once stone starts showing patchy areas and is staining easily then you should have it resealed. Give us a call and we can assist you with all your enquiries.
• Q: Can sealing effectively prevent efflorescence?
• A: Efflorescence is a phenomenon where salts migrate to the surface of porous materials during water evaporation, resulting in a whitish coating and potential damage to the surface finish. To effectively prevent efflorescence, it is crucial to apply a high-quality water-resistant sealer from a reputable range. However, it is important to note that efflorescence can also be influenced by factors such as water penetration. Therefore, it is essential to address any underlying causes of water penetration, such as repairing leaks or damaged grout, to effectively prevent efflorescence. By combining proper sealing with resolving the water source, proactive measures can be taken to minimize the occurrence of efflorescence and maintain the integrity of the surface.
