I want to add a backsplash with a 4x4 ceramic tile. I only want to go up 1 or 2 tiles in height not the whole wall area. Edges of the tiles are not black for the unfinished ceramic. How do I make the edges look finished or black also?
Most tile patterns have edge pieces just for this purpose. When you go shopping for your tile, check to see if there are matching edge pieces in the same color. Edge pieces are narrow, beveled or rounded off in some way so you can just butter them in along the last row of tiles and give it a finished look. Talk to the shop folks and see what they've got for you.
The edging tiles are the best way to go as everyone has said. If you are on a tight budget, you can use wood trim, like a small quarter round, and paint it to match the tile.
You can buy a ceramic edge in the same color or you can sometimes get tiles with a rounded edge on them. Make sure you get more tiles then you need cause if you go back to get more the color may be off some.
put cap over the top row of tiles. the cap tiles are usually 2 inches high by 6 inches long and they go right on top of the top row of tiles.
