Using caulk is one of the simplest and most recommended methods to finish glass tile edges. It creates an elegant seam between the glass tile and the adjacent area, along with a waterproof seal. With this method, you want to use a caulk color that matches the grout and, along with the grout, compliments the tile. Make sure the caulk line is smooth and even. Alternatively, you can use a bullnose or tile trimming to edge, however, that will also require caulk to seal.

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.

To make a small bathroom look bigger, choose light-colored tiles in a medium- to large-format size. Lighter colors like white, cream, or light gray help open up a room, making it feel larger and more airy. While it may seem counterintuitive, small tiles can actually make a bathroom look smaller because the increased number of grout lines creates a busy pattern that visually shrinks the space. Instead, opt for medium- or large-format tiles for a more seamless, expansive appearance. For the best effect, pair your tiles with a matching or similarly colored grout to create a continuous surface that enhances the illusion of a larger area. Avoid dark colors, heavy patterns, and contrasting grout, as these can make the space feel more confined.

Lack of durability is the most significant downside of painting tile. However, a painted tile backsplash doesn't see the same kind of action as, say, painted flooring tiles. For backsplashes, the durability of the finish is crucial because they often require cleaning. However, you can minimize the durability problem by using mild cleaners and water on the painted surfaces.
