  • Caulk the edge 
  • Rail moldings
  • Metal edges

How Do You Finish Tile Edges On a Backsplash?

Caulk the Edge

By far, the most cost-effective and easiest solution would be to caulk the edges of the tiles. Tumbled stones, mosaics, and most porcelain tiles have edges most suited for this solution. First, examine your tiling and determine whether they look raw or finished. If they look finished after grouting and installation, just apply a thin bead of caulking to the edge for a clean, watertight seal. If the edges look raw, seek out one of the other solutions below.

Rail Moldings 

Tile moldings for natural stone and porcelain are usually easily found. Thin, decorative, and easily customizable, rail moldings can make your tile installation look professionally done -even if it’s DIY! This solution is best for transitioning between tile styles or from tile to drywall. If your selected tile doesn’t come with molding, you can choose one yourself that closely matches or pick one that contrasts and adds some design flair!

Metal Edges

Metal edges are quickly gaining popularity with homeowners. They come in a large selection of styles and finishes. Metal edges can be used in kitchens, showers, indoors, and out. They’re a great addition to any tile project and will make it look superb. You can even choose a finish to match your sink or showerhead. A brushed nickel look would complete any bathroom or kitchen set.

Create a Bullnose Edge 

This is the more challenging solution, but not impossible. If you’ve chosen a tile that doesn’t have a matching trim, you can always ask your contractor to make a custom one. This solution usually only works with natural stone tiles or solid color porcelain tiles. If you are doing it yourself, make sure to practice, practice, practice! 

Do You Need to Seal Ceramic Backsplash?

Ceramic and porcelain are kiln-fired products; they are baked under high heat, making them very hard and highly resistant to liquid stains. They are available glazed or unglazed and in a multitude of colors. Ceramic and porcelain are often the easiest tiles to care for.

The surface of most ceramics does not need to be sealed. However, some do require a light penetrating sealer to help fill the micropores of the grout in between the tiles. Grout joints need to be sealed and maintained properly to ensure you don’t have stains or discoloration years down the road. Sealing your grout also prevents mold and mildew from growing. Be sure to choose a sealant based on your specific needs. 

Do You Grout Where Tile Meets Countertop?

While installing your backsplash, you notice a gap between your tiles and your kitchen countertop. Should you put grout there too? 

Houses settle over the years, so to ensure your backsplash looks amazing even years after you’ve done it, skip the grout and pick caulk instead. Caulking is more flexible, and grout may crack, making your backsplash look less than desirable. Be sure to pick a caulk color that matches your tile or grout.
