Frequently Asked Questions

Q: How often should tiles be fully resealed? - Sealing Natural Stone

• A: The recommended frequency for fully resealing tiles can vary depending on factors such as the type and quality of the sealer used and the expected lifespan of the sealer. It is advised to regularly assess the condition of the tiles and evaluate the effectiveness of the existing sealer. If there are visible signs of wear, staining, or diminished protection, it may be necessary to undertake a complete resealing process. The specific timing for resealing will depend on these factors, and it is important to consistently monitor the tile's condition and consult the manufacturer's guidelines or sealer recommendations to determine the appropriate intervals for full resealing.

Other FAQs :

• Q: What is the usual lifespan of the sealer before it requires reapplication?
• A: The lifespan of a sealer before reapplication is influenced by the type of sealer used. Topical sealers typically provide protection for approximately 3 years before requiring reapplication. In contrast, impregnating sealers are more durable and can last up to 15 years or even a lifetime when applied to vertical surfaces. However, areas with high foot traffic or frequent use may necessitate more frequent inspections and resealing to ensure ongoing protection. Conducting a water absorption test can help assess the porosity of the surface and aid in selecting a sealer with longer-lasting durability. It is advisable to refer to the guidelines provided by the manufacturer and consult professionals to determine the specific reapplication schedule suitable for your tiles and grout.
• Q: How long does the sealer need to dry for it to fully cure?
• A: The drying time required for a sealer to fully cure can vary depending on the specific product being used. In general, most sealers have a relatively quick drying time, with the surface becoming touch-dry within approximately 4 hours. This applies to both penetrating sealers and topical sealers. Penetrating sealers typically complete their curing process within 24 hours, while topical sealers may take up to 48 hours to fully dry. It is crucial to carefully follow the instructions provided by the manufacturer regarding the recommended drying time. Doing so ensures that the sealer properly sets and provides the intended level of protection. Adhering to the specified drying time will help guarantee the longevity and effectiveness of the sealer on your tiles.
• 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.
• 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: What is the purpose of using sealer and coating agents on stone?
• A: The idea of using sealers on stone surface is to prevent water from penetrating the porous structure of the stone, which eventually leads to stains, cracks, weathering, and deterioration. There are largely two types of chemical agents for stone cleaning.
