The mix for grout typically consists of a combination of cement, water, and fine sand. The exact ratio of these ingredients can vary depending on the specific type of grout being used and the manufacturer's recommendations. It is important to follow the instructions provided by the grout manufacturer to ensure the proper mix for the specific application. Additionally, some grouts may require the addition of a liquid polymer to improve flexibility and strength. **

Tile grout can be attacked by a variety of factors such as mold and mildew, dirt and grime, and general wear and tear. Mold and mildew can thrive in damp environments, leading to discoloration and deterioration of the grout. Dirt and grime can build up over time, causing the grout to become discolored and stained. Additionally, regular foot traffic and cleaning can wear down the grout, leading to cracks and gaps. **

To grout a brick wall with self-mixed mortar, start by mixing the mortar according to the manufacturer's instructions, ensuring it has a thick, paste-like consistency. Using a grout bag or a trowel, apply the mortar into the joints between the bricks, making sure to fill them completely. Use a pointing tool or a jointer to smooth the mortar and create a clean finish. Allow the mortar to set for the recommended time before cleaning off any excess with a damp sponge. **

Yes, you can color painted grout. There are grout colorants available that can be applied over painted grout to change its color. Make sure to clean the grout thoroughly before applying the colorant, and follow the manufacturer's instructions for best results.

For tougher stains, you can make a paste using baking soda and water, apply it to the grout, scrub, and then rinse. **

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. **

It is not recommended to apply grout over silicone. Grout is meant to be used in between tiles to fill gaps and provide a finished look, while silicone is a sealant used to prevent water damage and provide flexibility. Applying grout over silicone can lead to poor adhesion and a lack of durability, as the grout may not properly adhere to the silicone surface. It is best to remove the silicone before applying grout for a proper and long-lasting finish. **
