How to Fix Gap Between Backsplash and Wall Easily

You might have noticed a divide between your backsplash and wall. Maybe it’s been there since you installed the backsplash, or maybe it’s a new development. Either way, it can be frustrating to look at that unsightly gap every day. But the good news is that it’s easy to fix. Just follow these simple steps:

1. Prepare the Area:

If the gap is due to shifted tiles, remove any loose tile pieces. If the difference is due to an inconsistency in the installation, use a utility knife to score along with the backsplash so that it’s even with the wall.

2. Apply Caulk:

Using a caulking gun, apply a generous amount of caulk into the gap. Use your finger to soften the ledge so that it sits flush with the backsplash. If the gap is large, you may need to apply a second layer of caulk.

3. Apply Spackle:

Once the caulk is dry, apply spackle over the area with a putty knife. Smooth it out so that it’s level with the backsplash and wall. Allow the spackle to dry completely. It’s important to use spackle instead of caulking for this step because it provides a more seamless finish.

4. Sand the Area:

Once the spackle is dry, use coarse grit sandpaper to sand down the area until it’s smooth. Then, use fine-grit sandpaper to create an even smoother finish. If desired, you can paint over the area to match the rest of your backsplash or wall.

5. Enjoy Your New, Improved Backsplash:

You’ve successfully filled the gap between your backsplash and wall. Enjoy your new, improved backsplash.

Reasons for Gaps between Backsplash and Wall

It’s possible you’re wondering why there’s a space between the wall and the backsplash in the first place. The following reasons may cause gaps to form between your backsplash and wall:

Incompatible materials are usually not easy to fix and may require professional help.

3. Inconsistent Tile or Countertop Installation:

5. Shrinkage:

An additional cause of gaps between the backsplash and the wall is shrinkage. As a result, the materials used to make the backsplash or wall contract or expand at different rates.
