Can Backsplash Be Installed on Drywall?

Installing a beautiful backsplash is one of the most popular ways to upgrade a kitchen or bathroom. Backsplashes not only provide an extra layer of protection behind sinks and stoves, but they add style, color, and personality to the space. Many homeowners opt for tile backsplashes, but did you know you can install a tile backsplash directly on drywall? Here’s what you need to know about installing backsplash on drywall.

What is Drywall?

Drywall, also known as gypsum board or wallboard, is a panel made of gypsum plaster pressed between two thick sheets of paper. It’s a common interior wall material used in many homes and buildings. Some key advantages of drywall include:

  • Cost effective
  • Easy to install and repair
  • Provides fire resistance
  • Creates smooth finishes for decorating

Drywall offers an affordable blank canvas to apply finishes like paint, wallpaper, or tile. While it’s not as durable as materials like concrete or brick, drywall can be used to create beautiful, functional spaces when installed correctly.

Can You Install Backsplash Tile on Drywall?

The short answer is yes, you can install a tile backsplash directly onto drywall in most cases. Here are some tips to do it right:

Use Cement Board for Wet Areas

In bathrooms or behind sinks/stoves where the backsplash will be exposed to moisture, use cement backerboard rather than plain drywall. Cement board provides extra water resistance. Apply a waterproof membrane over the cement board before tiling for maximum protection.

Check for Moisture Resistance

Verify that the drywall in the installation area is moisture and mold resistant. Look for labels indicating the drywall is safe for tiled surfaces.

Prepare the Surface

The drywall needs proper preparation before installing tile. First, make sure the area is smooth, clean, and free of debris. Next, apply a primer coat of drywall sealer to create a bonding surface for thinset mortar.

Use Adhesive and Grout

Use a polymer-modified thinset mortar adhesive to attach the backsplash tiles directly to the drywall. Make sure the coverage is even and complete. Use unsanded grout between the tile joints for the best finish.

Seal with Caulk

Once grouted, run a bead of waterproof caulk between the backsplash and countertop/sink to prevent moisture penetration. Silicone caulk works best for kitchens.

Drywall Backsplash Installation Tips

Follow these tips for a successful backsplash installation on drywall:

  • Clean surface thoroughly and apply sealer/primer before tiling
  • Use cement board for high-moisture areas
  • Apply waterproof membrane behind sinks or stoves
  • Use polymer-modified thinset mortar adhesive
  • Grout with an unsanded product
  • Caulk edges with waterproof sealant
  • Make sure drywall is moisture/mold resistant

With proper prep and materials, you can achieve a gorgeous, durable backsplash on drywall. Take moisture precautions behind sinks and stoves to prevent damage over time. Make sure to use mold-resistant drywall and waterproof adhesives for the best results.

Drywall Backsplash Pros and Cons

Installing backsplash tile on drywall has both advantages and disadvantages:


  • More affordable than cement board
  • Lightweight and easy to cut and install
  • Simple surface preparation
  • Provides a smooth backdrop for tile


  • Vulnerable to moisture damage over time
  • Not as durable as cement backerboard
  • Can sag or deteriorate if not properly sealed
  • Requires careful prep and waterproofing

Alternatives to Drywall for Backsplash

If you’re concerned about long-term durability or moisture resistance, consider these alternatives to drywall for your backsplash project:

  • Cement Backerboard – Made from concrete and fiber mesh, provides maximum stability and water resistance behind a backsplash.
  • Glass Tiles – A non-porous option resistant to water and stains. Easier for DIY installation.
  • Stainless Steel – A modern look that is highly water-resistant and easy to clean. Can be installed over drywall.
  • Peel-and-Stick Tiles – Self-adhesive backsplash tiles that go up easily and come off cleanly. User-friendly DIY option.
  • Painted Drywall – Use semi-gloss paint and primer to create a budget-friendly, wipeable faux backsplash on drywall.

No matter what material you choose, make sure to properly prepare the surface, use waterproof adhesives/grout, and caulk edges for the most durable finish.

Frequently Asked Questions About Backsplash on Drywall

Can I use regular drywall for a backsplash in the kitchen?

For best results, use moisture-resistant drywall behind kitchen sinks and stoves. Apply a waterproof membrane as added protection. In low-moisture areas, standard drywall may be OK.

What kind of tile adhesive should I use?

Use a polymer-modified thinset mortar adhesive to attach backsplash tiles to drywall. This provides a strong, water-resistant bond.

How do I prepare drywall for a tile backsplash?

Lightly sand the drywall, then apply a coat of drywall sealer/primer. This creates a bonding surface for the thinset mortar adhesive. Wipe away dust before tiling.

Should I use sanded or unsanded grout?

Unsanded grout is recommended for backsplash installations with small tile joints less than 1/8 inch. It creates a smoother finish. Use sanded grout for wider grout lines.

What’s the best way to seal the edges?

After grouting, run a bead of silicone caulk along the top edge and sides where the backsplash meets the wall or countertop. Tool the caulk to smooth it out.


Installing a tile backsplash on drywall is definitely doable with the right materials and techniques. To account for the vulnerabilities of drywall, be sure to take moisture protection measures behind sinks and stoves. Prep the surface properly, use water-resistant adhesives and grout, and always caulk the edges to prevent water intrusion. With careful installation, a drywall backsplash can provide a beautiful, cost-effective upgrade to your kitchen or bath.
