How To Install Backsplash with Adhesive Tile Mats

Homeowners who want to install kitchen backsplashes without the hassle of mortar and grout should consider using adhesive tile mats. These materials can transform your kitchen just as convincingly as traditional backsplash tiles, but they are much easier to install, and don’t take as much time. Read our guide below for tips on how to install a backsplash with adhesive tile mats, and watch the video above for tips from House One’s Jenn.

Understanding Adhesive Tile Mats

Adhesive tile mats are double-sided sticky sheets that you can use instead of traditional mortar as part of tile installations. Adhesive tile mats are easier and cleaner to install, and perfect for do-it-yourself enthusiasts.

Benefits of Adhesive Tile Mats

• Immediate grouting: You can grout tiles immediately after installation, which saves time.
• Less mess: The sticky sheets eliminate the need for wet mortar, which reduces necessary cleanup.
• No mixing required: Adhesive mats come ready to use.

Potential Drawbacks

• Cost: Adhesive mats can be more expensive than traditional mortar for larger projects.
• Durability concerns: Some professionals question the long-term success of adhesive tile mats as compared to traditional materials.
• Limited adjustability: Once you’ve placed tiles, it’s difficult to adjust them.

Preparing for Backsplash Installation With Tile Mats

You must properly prepare for your installation by gathering the necessary materials and tools and organizing your workspace.

Gathering Materials and Tools

Make sure you have the tools and materials below before you begin your project. 

• Adhesive tile mats
• Damp sponge
• Dry towel
• Grout float
• Herringbone mosaic tile
• Painter’s plastic sheeting
• Painter’s tape
• Pencil
• Rubber float
• Ruler
• Sanding sponge
• Screwdriver
• Spacers
• Tape measure
• Tile saw
• Unsanded grout
• Utility knife

Preparing the Work Area

1. Remove any existing backsplash tiles.
2. Sand the wall surface lightly and patch any imperfections.
3. Turn off power to electrical outlets in the work area.
4. Remove outlet covers and switch plates.
5. Cover countertops with plastic sheeting to protect them during installation.

Installing the Adhesive Tile Mats

Start your installation project by applying the adhesive mats to the wall surface you’ve prepared. This creates the base onto which you’ll attach your tiles.

Applying the Adhesive Mats

1. Start at the top of the backsplash area, and align the mat with the underside of the cabinets.
2. Unroll the mat vertically, and smooth it down as you go.
3. Use a utility knife and straightedge to trim the mat at the countertop.
4. Press the mat firmly into place using a grout float.
5. Continue applying mats in vertical strips, and align edges carefully.

Navigating Obstacles

Follow the steps below if you encounter outlets or other obstacles: 

1. Lightly place the mat over the obstacle.
2. Carefully cut around the outlet or obstacle with a utility knife.
3. Press the mat into place, and make sure all edges are secure.

If you encounter corners, pre-cut the base of the strip and bend it into the corner before making a vertical cut along a straightedge.

Preparing and Cutting Tile

Working with herringbone mosaic tile requires careful planning and precise cutting. This pattern can be challenging, but the results are visually striking.

Layout and Pattern Alignment

1. Lay out all tile sheets on a flat surface before you begin installation.
2. Make sure the herringbone pattern aligns consistently across all sheets.
3. Mark cut lines for the bottom and left edges of the first sheet.
4. Use tape to secure any loose tiles on the mosaic sheets

Cutting Techniques

Follow the steps below when you’re cutting herringbone mosaic tile:

1. Use a tile saw for clean, precise cuts.
2. Consider placing a board on the saw’s sliding plate to support small tile pieces.
3. Cut slowly to minimize chipping, especially on corner pieces.
4. Dry tiles thoroughly after you cut them so that they adhere properly

Applying Tiles to the Adhesive Mat

Once you’ve put your mats in place and cut your tiles, you can begin installing the tiles. This process requires patience and attention to detail.

Tile Application Process

1. Remove the protective layer from the adhesive mat.
2. Carefully align the first tile sheet, and leave a small gap for grout along the walls and countertops.
3. Press the tile sheet firmly into place using a rubber float.
4. Hold each section for about 5 seconds to make sure it properly bonds.
5. Continue applying tile sheets, and maintain consistent spacing and pattern alignment.

Handling Outlets and Edges

Follow the directions below when you encounter outlets:

1. Mark tiles that overlap the outlet.
2. Use a utility knife to remove backing and tile from these marked areas.
3. Carefully fit the remaining tile around the outlet.

Follow the directions below when dealing with the top row:

1. Use spacers to maintain consistent spacing with the ceiling or cabinets.
2. Cut tiles to fit the remaining space.

Grouting and Finishing Tile Backsplash

The final step in your backsplash installation is grouting. This process fills the gaps between tiles and gives your backsplash a polished, complete look.

Grouting Process

1. Mix grout according to the manufacturer’s instructions.
2. Apply grout diagonally across tile joints using a grout float.
3. Work in small sections to make sure coverage is even.
4. Use a damp sponge to clean excess grout from tile surfaces.
5. Allow grout to dry according to the package’s directions.
6. Buff the tile surface with a dry towel to remove any remaining haze.

Final Touches

Follow the steps below once the grout has fully cured:

1. Apply grout sealer.
2. Reinstall outlet covers and switch plates.
3. Caulk along the countertop and any edges where the backsplash meets another surface.

Troubleshooting Common Issues With Adhesive Tile Mats

You may encounter issues even if you properly plan your installation. Read below for tips on how to troubleshoot potential problems: 

Misaligned Tiles

If your herringbone pattern is misaligned, gently remove the tile, press it into the adhesive mat, and check the alignment. Once you’re satisfied, press it firmly into place.

Grout Haze

A haze may form on the tile surfaces after you’ve grouted. Use a grout haze remover or a mixture of vinegar and water to clean this off. Buff the tiles with a dry towel to restore their shine.

Uneven Grout Lines

Use a grout scorer to even out uneven grout lines while the grout is still workable. Reapply fresh grout to the scored lines and smooth it with a float.

Adding the Backsplash Finishing Touches

Once the grout and adhesive have set, you can move on to your project’s final touches. 

Reinstalling Fixtures

Once everything is dry and cured, reinstall any fixtures, outlet covers, and switch plates. Make sure all electrical components are secure and working before you finish up your project.

Sealing the Grout

Grout sealing protects against moisture and staining. Apply a grout sealer according to the manufacturer’s instructions to maintain the fresh look of your new backsplash. 

Caulking Edges

Apply a bead of caulk where the tile meets countertops, cabinets, and walls to give your backsplash a clean look. Caulking seals gaps and prevents moisture from seeping behind the tiles.
