Frequently Asked Questions

Other FAQs :

• Q: Why do I still see marks on my polished marble/limestone/travertine even though it has been sealed?
• A: Even though your polished marble/limestone/travertine has been sealed, you may still notice marks on the surface. It's important to understand that these marks are often not stains but rather etches. Acid-sensitive stones, such as these, can be affected by any acid, which can lead to a loss of polish and the creation of a dull or frosty surface. For example, red wine can cause both a stain and an etch on unsealed stone, but on a sealed stone, only the etch may be visible. Penetrating sealers function by sitting below the surface of the stone, preventing acid from deeply penetrating and causing stubborn stains, but they may not fully protect against surface etching. Acid can come in various forms, such as fruit juices, wine, salad dressings, or even urine in bathroom settings, and can cause damage. The good news is that this type of damage can typically be repaired.
• Q: What is the recommended frequency for re-sealing a stone surface?
• A: The recommended frequency for re-sealing a stone surface is typically every 5 to 10 years, depending on the quality and type of sealer used. Some premium sealers can last even longer, up to 15 years or even a lifetime. Special stone seal removers are available for resealing natural stone floors. With proper care and maintenance, a natural stone floor can maintain its natural finish for a lifetime. It is crucial to use the appropriate products specifically designed for your type of natural stone floor to ensure its longevity and appearance. Additionally, it is important to seal other stone features such as stairs, tables, pillars, and fireplaces to protect them from staining and damage. Fireplaces, in particular, can be susceptible to staining from carbon deposits and UV damage, making sealing essential for their preservation.
• Q: What are the reasons for sealing a stone surface and when is the ideal time to do so?
• A: Sealing a stone surface is crucial to prevent immediate staining from spills and to protect against permanent damage. While sealing provides effective protection, it is important to clean up spills promptly. Different natural stone surfaces require specific sealing methods. For sandstone, terracotta, and limestone, it is recommended to seal them before they are laid and grouted. These materials are highly porous and can quickly absorb stained water from adhesives and grout. Terracotta, in particular, should be sealed on all sides before installation due to its high porosity. Limestone is also susceptible to staining, and caution should be exercised while handling it to avoid leaving finger marks that can later stain the surface. Granite, marble, slate, and travertine, on the other hand, are sealed on all edges and the top after they are laid and grouted. Thorough cleaning is essential prior to the sealing process for these types of floors.
• Q: What steps should I take to maintain my floors after they have been cleaned and sealed?
• A: The technician who performs the cleaning and sealing of your floors will provide you with personalized maintenance advice specific to your tiled area. In general, we recommend using a mild cleaner, such as Spirit "Neutral Cleaner," at least once a week to keep your tiled floors well-maintained. Tiles with a textured surface may benefit from using a doodlebug instead of a mop for a more effective clean. It is important to avoid the use of harsh chemicals as they can diminish the longevity of the sealers. Additionally, when mopping, remember to change the water frequently to prevent spreading dirty water across your floors.
• Q: Does sealing my pavers or stone prevent the growth of algae?
• A: Sealing alters the properties of the pavers or stone but does not modify the surrounding environment. If your backyard is damp and shady, the sealing product cannot change those conditions. However, sealing reduces the porosity of the pavers or stone, thereby inhibiting the growth of algae and making cleaning easier. In most situations, it is advisable to consider sealing as a beneficial option.
