Want to add a backsplash but have a gap between the wall/countertop

Have you looked at the big box stores for small tiles that might fit just right in this gap? They make them in just about all sizes. Measure this gap and go looking. I would suggest not using a glass because you can see through it to the glue!

There was a severe change in the manufacturer of our flooring so we could not buy the old type flooring we had down to weave it in. I HATE pieces of raised wood used to join flooring. So we put down some tile that was to be used as borders in kitchens (wider than what you would want). We adjusted the slight difference in height by using a little more of the Epoxy Compound we used for glue. If there is a big difference, you can nail in some strips of a thin wood. Balsam wood can be bought at the hobby stores.

Once it dries for 24 hours, grout like you would any tile. Ours came on a web backing.

This has been down a good 7-8 years and not a piece has shifted.

I would try and find a rounded small tile, bullnose type and place it flush on the countertop to the wall. Of course, this would not be a good idea if you are planning to replace the countertop anytime soon.

I would fill the gap with wood level with counter surface the surface. Then put on the backsplash. Use pencil tile to cover the filled in gap.

I would go to a store that sells wood trim and get a nice piece of trim to cover the gap. You could paint it either the same color as your countertop or a color that would be a highlight color in your kitchen. I would also use a clear cost to protect the wood do you could clean it. Use a tube of wood adhesive to glue it to your wall and the top of the counter top edge.

Put a sheet of the thin plywood up first. It will not only take the gap out but will make it easier to put your backsplash on.

I had that too, so I jammed a rope large enough to fit tightly into the gap, and then put a bead of silicone calk over the rope, connecting the counter with the wall or backsplash.

Thanks. We surprise ourselves with what we can come up with when we find a problem! Hometalkers are the BEST!!

I had this problem and filled the space with quarter round corner tiles. They covered the space perfectly.

I'm thinking of adding a 1/4 round piece of wood trim when finished. If that doesn't work you could try 1/4 round tiles that will give you a complete look. Any change of filling the gap area with a strip of 5/8" scrap wood?

Best of luck.

I would use outside corner molding! It comes in different dimensions. 1/4 inch is probably all you would need. Put a bead of caulk in crevice portion, put half of behind current backsplash with the other edge hanging over current backsplash! You can paint it. Or they have a white plastic one. Located in trim section. Anyone at Home Depot or Lowe’s can help you find it. Hope this makes sense!

I would consider the PVC molding, which is plastic and would withstand some of the conditions on a kitchen counter, like spills, frequent cleaning, etc.

Jeanette S, I love your solution. To the original poster, I would paint a strip of quarter round to blend between the raised countertop and the new backsplash. Glue the quarter round in place. You could also use it at the backsplash top or the ceiling seam. 😇

I used backerboard. After backsplash was installed, I just used a bead of caulk.

You could use thick splashback tiles to take up the space or ordinary tiles and a tile shaped to fit the gap and join the top to the walls.

Hi Gina, If you are ready to add a corner round or other piece in to fill the gap, you can always use caulking, just mask off the area so it does not go out of the area you are filling to ensure it stays between the lines. Pull off the masking tape before the caulking dries to avoid a disaster. Hope this helps you out.

Quarter-round molding would cover it.

Cover the gap but don't put a back splash above the 4 inch one you already have. If you want a nice back splash take the counter out and tile the entire wall (if you have a big kitchen and only about a foot or so high if you have a small kitchen).
