Can You Fix The Gap Between Backsplash And Wall? (How To)

There are times when a gap may appear between the backsplash and the wall. This is an issue that tends to happen over time but it is also one that is fixable. What can you do to fix it?

The easiest and best way to fill a gap between the wall and backsplash is to fill the gap with caulking. A tub and tile caulking would work best because it is easy to work with and is paintable. You can also use a silicone sealant, but it is not as easy to work with.

If you notice the gap and it is relatively small, you can likely fill it with a single bead of caulking. There may be times, however, when the gap is too large for the caulking to stay.

When you have a large gap or if part of the gap is large, you should use some spline, sometimes called a backer rod to fill the gap. The backer rod will fit down in the gap and fill up most of the area so you can come through with caulking at a later time.

When you use caulking to fill the gap between a backsplash and wall, you’re essentially just filling the gap with material and then finishing it off. There may be times, however, when another material is desired.

If you are dealing with a solid surface backsplash, such as granite or similar material, then caulking is going to be the best choice. If you have a tile backsplash, however, you may want to use grout.

Grout fills in the hole nicely and it also will stay in place for a lot longer. That being said, there are also times when the grout may crack when it dries, so you need to use good judgment.

If the gap between the backsplash and the wall is relatively small, a little bit of grout is going to fill it just fine. You won’t even notice the fact that you are filling a gap. On the other hand, make sure you use some backer rod if the gap is large to keep the grout from sinking and cracking.

One of the questions that many people have is in regards to finishing things off after you use caulking. You can paint the caulking, as most types of caulking are paintable.

You may also wonder if it should be painted the color of the backsplash or if it should be painted the color of the wall.

In every case, paint the caulking the color of the wall so it will blend in nicely and practically disappear. If you try to paint it the color of the backsplash, it’s difficult to differentiate between the backsplash and the wall when changing colors.

Let’s take a look at some of the reasons why the gap between the backsplash and the wall exists. We will also discuss why it occurs and what you can do to fix it.

Why You Should Fix The Gap Between Backsplash And Wall

Some homeowners may wonder if they should just leave the gap between the backsplash and wall alone. Is it something that should be fixed?

The decision to fill the gap between the backsplash and wall or to otherwise fix it is a personal one. Since the decision to do so often has to do with the look, it is really a matter of ‘beauty is in the eye of the beholder.’

I’m sure that most people would agree, however, that an unsightly gap between the backsplash and wall is something that should be filled in almost every instance. Since it only takes a few minutes to fix, it’s not something that should be put at the bottom of your to-do list.

It isn’t only about looks, however, there may actually be some problems associated with the gap that needs to be considered. Since the backsplash is there to keep moisture from getting down between the wall and the countertop, the gap at the top of the backsplash may allow it to happen at that point.

If water does get down in the gap, you are headed for problems. It can rot the cupboard underneath the edge and often where you can’t see the issue happening. This could leave you with some additional problems, including the countertop separating from the vanity.

Even in the kitchen, there are many things that can get down in that gap and some of them could be unsavory if they are allowed to be there, such as rotting food. Filling the gap corrects the issue from the very start. It doesn’t allow the problem to happen.

What Is Causing The Gap Between Backsplash And Wall?

You might be interested in knowing why the gap exists between the backsplash and the wall. Not only will this help you to see why it needs to be fixed, but it will also allow you to see what can be done to prevent the problem from happening in the first place.

Shifting – It is normal in many homes for the foundation to shift and settle. If that happens in your home, you may have a gap form between the backsplash and the wall.

The gap that you see is not always indicative of the gap that may exist between the vanity or cupboards and the wall. Often, it is the worst-case scenario at that point when the separation happens.

Rotting Wood – Unfortunately, the cupboards are in a part of the home where water is often an issue. It can happen under the sink or even if water gets into a gap and is allowed to stay there. The wood for the cupboards can rot very easily, as they are often made from particleboard.

When the wood rots, particularly on the floor, the cupboards may shift. As a result, you may see the gap beginning to form.

Improper Installation – If the cupboards were not installed properly, you may have a problem with them shifting and moving. This could be due to not using construction adhesive or perhaps you didn’t screw into a stud when attaching the cupboard to the wall.

In any case, it may be necessary to reinstall the cabinet or to shore up the cabinet if it is shifting underneath. Doing so will help to keep the gap from continuing to form in the future.

How To Prevent Gaps From Forming Between Backsplash And Wall

If a gap has formed between the backsplash and the wall, it is too late to prevent the problem. The time to prevent the issue is before it occurs.

Using the proper installation techniques when putting in the cupboards, countertop, and backsplash is the only way to prevent the gap from forming between the backsplash and wall.

Included in the installation should be construction adhesive, which will affix the cabinet to the wall. You should also use adequate screws that go through the the cupboard and into the wall at a position where they can screw into a stud. Otherwise, the screw is going to pull out over time.

If the countertop is not installed properly, it is likely to shift and this is a big problem that can lead to a gap between the backsplash and the wall. Make sure that the countertop is installed flush and is properly supported by the cabinets.

3 Ideas To Fix The Gap Between Backsplash And Wall

1. How To Fix The Gap Between Backsplash And Wall (Caulking)

The easiest way to fix the gap between the backsplash and the wall is to hide the gap. How do you do this?

Caulking is the best method for fixing the gap between a backsplash and wall. Running the bead of caulking in this area will hide the issue immediately. On thicker gaps, you may need to use some backer rod before using the caulking.

After applying caulking to the area, use a tool or your finger to wipe the caulking so it is flush and fills the gap appropriately. You should then use a damp rag to clean the caulking from the countertop and top of the backsplash.

Allow the caulking to dry and then paint it the color of the wall. The gap will be gone.

2. How To Fix The Gap Between Backsplash And Wall (Spackle)

Sometimes, you may need to use drywall mud or spackle in the area with the gap between the backsplash and the wall. Essentially, you are filling it with something that is a caulking substitute. Use a putty knife to smooth in the spackle and after drying, you can paint it.

One step that should be done in this instance is to use some sandpaper or a damp rag or sponge to smooth out the area before painting. Most people prefer to use wet sanding because it does not create a lot of dust.

3. How To Fix The Gap Between Backsplash And Wall (Molding)

If the gap between the backsplash and the wall is excessive, how can that be fixed?

You can hide the gap between the backsplash and the wall by using some decorative molding. This will essentially add to the height of the backsplash but it will also effectively hide the gap nicely. You may need to use caulking if any small gaps exist.

Decorative molding is not going to be an option that is preferred by most homeowners. It is something to consider, however, if the gap is too wide to fix otherwise.

You can use caulking behind the gap between the backsplash and the wall. Backer rod can also be used in this area if the gap is large. After caulking, allow it to dry, and then paint the caulking the color of the wall.
