There are several different products that allow underwater repair. Pool putty can help repair chips, cracks, and loose tiles without draining your pool, but it should only be used for a temporary fix. Certain two-part epoxy adhesives will cure underwater, too. That said, while it is technically possible to fix pool tiles underwater, it is usually not ideal, depending on the depth of your pool. You will still have to reach the tile, which means you might have to dive and make the repair while submerged.

Whether you want to match your tile trim with grout comes down to your personal preferences. If you match the two, it can help your tiles to stand out while providing a clean, cohesive look. On the other hand, you might opt to match your tile trim with your tiles. The best option will depend largely on your tile design, as well as how it fits overall with the rest of your room.

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.

You can, in theory, tile your fireplace hearth with most tiles. However just because you can, doesn’t mean you should. For example, it’s much better to use unglazed tiles because glazed tiles are more resistant to cracking under extreme heat. Porcelain is more heat-resistant than ceramic, but you can still design the hearth as you like by putting the most heat-resistant tiles directly under the fire and, if it matches your style, add more decorative tiles further from the center of the fire.
