Tile grout can turn white due to a variety of reasons. One common reason is the accumulation of soap scum, dirt, and other debris that can discolor the grout over time. Additionally, grout can become discolored due to mold and mildew growth in damp or humid areas. Harsh cleaning chemicals or improper cleaning techniques can also cause grout to turn white as they strip away the original color. Finally, natural wear and tear can cause grout to lose its original color and become white over time. **

The white coating on the tile is likely efflorescence, which is a deposit of soluble salts that can form on the surface of masonry materials like tiles. This occurs when water carrying the salts evaporates, leaving the salts behind. Efflorescence is often seen in areas with high humidity or water exposure, and can be removed with cleaning solutions or by addressing the underlying moisture issue. **

The white spots on the tile floor are likely caused by a buildup of mineral deposits from hard water. When water with a high mineral content evaporates on the tile surface, it leaves behind these white spots. Another possible cause could be the use of harsh cleaning products that leave behind a residue on the tiles. Regular cleaning and using a mild acidic solution can help remove these white spots and prevent them from reoccurring. **

For oil painting, odorless mineral spirits are recommended as a substitute for turpentine (White Spirit). Odorless mineral spirits are less toxic and have a milder odor compared to traditional turpentine, making them a safer option for artists to use in their studios. They can effectively thin oil paints, clean brushes, and remove excess paint from palettes without compromising the quality of the artwork. **

To repair a white tile if a corner has broken off, you can start by cleaning the area around the broken tile to remove any debris or dust. Then, use a tile adhesive to carefully glue the broken piece back into place. Hold the piece in place for a few minutes to allow the adhesive to set. Once the adhesive has dried, you can use a white grout to fill in any gaps and smooth out the repaired area. Finally, wipe away any excess grout and allow it to dry completely before using the tile. **

The choice between tile paint and tile color depends on personal preference and the desired outcome. Tile paint is a quick and cost-effective way to update the look of tiles, but it may not be as durable or long-lasting as tile color. On the other hand, tile color involves replacing the tiles entirely, providing a more permanent solution with a wider range of color options. Ultimately, the decision between tile paint and tile color should be based on factors such as budget, time constraints, and the desired longevity of the update. **

The thickness of the tile adhesive after drying, including the tile, can vary depending on the type of adhesive used and the application method. Generally, the adhesive layer can range from 1/8 inch to 1/4 inch thick. It is important to follow the manufacturer's recommendations for the specific adhesive being used to ensure proper adhesion and long-term durability of the tile installation. **
