Silicone caulk shouldn’t be used in place of grout because each material serves its own purpose. Thanks to its flexibility, silicone caulk is good for sealing around the perimeter of tiled floors, where movement and expansion might occur. However, grout is more durable, making it a better option for the joints in between tiles, which need to withstand constant weight and foot traffic.

Yes, you can tile over existing tiles in a bathroom, but it is not always recommended. For this method to be successful, the original tile surface must be clean, flat, and free of damage such as cracks, unevenness, mold, or mildew. While tiling over existing tiles can save time and money, there are potential drawbacks. The new adhesive may not bond properly, and the process adds extra weight to the wall or floor. Additionally, the increased height of the surface could interfere with door clearances. For the best and most durable results, removing the old tiles before installing new ones is generally the better option.

When choosing between porcelain and ceramic tile, the best option depends on your specific needs, budget, and project application. Porcelain tile is generally more durable, denser, and harder than ceramic, making it a good choice for busy, high-traffic areas. It also offers superior moisture resistance, making it ideal for moisture-retaining spaces. However, porcelain is typically more expensive, and its hardness can make it brittle, potentially causing it to crack if a heavy object is dropped on it. In contrast, ceramic tile is a more budget-friendly option with lower material and installation costs. It is softer and easier to work with, making it a great choice for DIY projects. While not as durable as porcelain, ceramic is still a quality material suitable for many home applications, particularly small, decorative projects.

Installations typically take 1-3 days, depending on area size; repairs are usually completed sooner if the issue is localized.
