Can You Put a Backsplash Directly on Drywall?

A backsplash adds a layer of pizzazz and protection to the wall above your kitchen counter, sink, and stove. If you're thinking of adding a new backsplash, you may wonder: Can you put backsplash on drywall? The short answer is yes, you can. But there are a few important things you need to know about installing a new backsplash on your kitchen drywall.

Why It's Safe to Put a Backsplash on Drywall

Installing a backsplash on your kitchen's drywall is safe and effective because it's not a highly moist surface, such as a bathroom wall that gets a lot of steam. As long as the drywall is clean and smooth, you shouldn't have any trouble installing a backsplash over the top of it. 

It’s also relatively simple. In most cases, you don't need to tear out existing drywall to install a backer board for this project since the area doesn’t get foot traffic like a tile floor.

Choose the Right Type of Drywall

Drywall comes in a range of types, including standard drywall, which is appropriate for use around the home, and moisture-resistant green-board drywall, which is a good pick for rooms like the kitchen and bathroom.

Green-board drywall has a paperless backing and an additional coating that blocks moisture and reduces mold growth. While you may not need to tear out your existing drywall and replace it with a moisture-resistant option, it's something to consider if you're starting from scratch or completely remodeling your kitchen. 

How to Prep the Drywall

Whether it's a tile or quartz backsplash, or even a peel-and-stick option, wall prep before installation is a must. Kitchens get dirty quickly, especially if you cook frequently. Grease can build up on the wall, interfering with the adhesion of the backsplash.

Use a degreaser to clean the drywall above the counter, making sure to thoroughly remove any stains. Once you've cleaned the wall, fill in any divots with a spackling compound. When that's dry, sand the wall to get a smooth surface.

Finally, wipe the wall with a damp rag to remove the sanding dust, then let dry. 

How to Install a Backsplash on Drywall

How you install a backsplash depends largely on the materials you're using. To install a tile backsplash, you'll first want to attach a ledger board to the wall. 

The ledger board will support the tile's weight as the adhesive dries. 

Before placing the tile on the wall, plan its layout. You can spread the tile out on the floor or another flat surface and arrange it in the pattern you want. 

When you start applying the tile to the wall, work in small sections, starting from the center. Apply the adhesive to the wall, then press the first tile against it. Install the remaining tile, working slowly and checking your work as you go to ensure everything is even. 

Once the tiles are on the wall, it's time to apply and seal the grout.
