How to Install Glass Backsplash Around Outlets

Installing a glass backsplash is a great way to add style and visual interest to your kitchen. However, dealing with outlets that are located in the backsplash area requires some special consideration and techniques. Properly installing outlets within a glass backsplash ensures the backsplash has a seamless, professional look and the outlets are safely and properly wired.

Planning Your Outlet Placement

Before starting your backsplash installation, take time to map out where any outlets are located and decide if you need to relocate them.

  • Having outlets right against an edge or corner of the backsplash pieces can make installation more challenging and leave outlets partly obstructed.
  • For a cleaner look, consider moving outlets at least 4-6 inches away from any backsplash seams or edges. This allows the backsplash pieces to completely surround the outlet.
  • Another option is to remove unused outlets altogether and drywall over them. Just be sure to turn off the circuit breaker, remove the wiring, and screw the outlet box securely in place before drywalling.
  • If you do need outlets remain in their current locations, choose backsplash pieces that work around them. Using a combination of full tiles, mosaic sheets, and carefully cut irregular pieces can help seamlessly integrate outlets.

No matter where your outlets are located, always double check that their placement meets all local electrical codes before proceeding. Planning ahead of time will make the installation process go much more smoothly.

How to Remove Old Backsplash Around Outlets

If there is existing backsplash around your outlets that needs removed before installing the new backsplash:

  • Turn off the power at the circuit breaker to avoid risk of shock.
  • Carefully cut away grout lines around the outlets with a utility knife. Break apart the backsplash pieces using a hammer and chisel.
  • Protect the drywall from damage and pull away pieces slowly.
  • Once the backsplash is removed, unscrew the outlets and pull them out of the electrical box while leaving wires attached.
  • Fit a box extender as needed to make sure the outlet will sit flush with the new backsplash.
  • Apply new drywall mud around boxes to smooth and fill any uneven gaps. Sand once dry.
  • Thoroughly clean all electrical boxes before reinstalling outlets.

Follow safety precautions and turn power back on only after the new backsplash is completely installed.

How to Install Outlets Before New Glass Backsplash

If updating outlets or relocating them, it’s best to install the electrical boxes and outlets prior to the glass backsplash installation.

Step 1: Installing New Outlet Boxes

  • Choose outlet boxes that sit flush with the wall surface. Box extenders can be added to adjust how far boxes protrude.
  • Mark the new box locations and cut holes in the drywall using a drywall saw.
  • Feed electrical wiring into the boxes and secure them with mounting screws. Make sure they sit perfectly flush.
  • Seal around the boxes with drywall mud to prevent moisture getting in behind the backsplash.

Step 2. Installing the Outlets

  • Attach the outlet securely to the box once the mud dries. The outlet should sit flush or just slightly recessed in the box.
  • If needed, break off the side tabs on the outlet cover plate so it sits flat against the backsplash.
  • Run wires through the outlets and make proper connections by matching wire colors using screw terminals.
  • Use electrical tape to insulate splices. Follow codes for inside outlet boxes.
  • Attach the outlet cover plate and test for proper function before installing backsplash.

Correctly installing new outlets before adding the glass backsplash ensures a safe, seamless look.

Cutting Outlets Holes in Glass Backsplash Pieces

To install glass backsplash tiles or panels around existing or newly installed outlets, properly measure and cut any specialty outlet openings needed:

Measure Carefully

  • Turn outlet power off. Removing the cover plate, use painters tape to mark the exact outlet position on the wall.
  • Transfer measurements to the backsplash piece. Mark the exact outlet location.
  • Double check measurements before cutting to avoid mistakes.

Cut the Opening

  • Use a glass cutting tool to score the outline of the opening at least 1/8″ inside your marks.
  • Consider glass thickness when calculating interior cutout size. Don’t cut too small.
  • Tap the backsplash piece along the score line to split the glass. Repeat to remove interior cutout piece.
  • Use a grinder or sandpaper to smooth rough edges. Finish exposed edges for safety.
  • Dry fit backsplash to outlet before permanently adhering.

Cutting backsplash openings accurately the first time prevents delays in the project timeline.

How to Install Backsplash Around Outlets

Once all outlets are properly installed and any special backsplash cutouts made, putting up the backsplash is fairly straightforward:

  • Clean the wall surface thoroughly where backsplash will be applied using denatured alcohol. Remove any outlet cover plates.
  • Spread a thin, even layer of tile mastic adhesive on the wall area using a notched trowel. Do not get adhesive in the outlet boxes.
  • Press backsplash pieces firmly into place. Insert cut tiles around any outlets or openings.
  • Use plastic outlet box covers during installation to avoid getting mastic or debris in boxes.
  • Let adhesive fully cure according to manufacturer instructions, usually 24-48 hours.
  • Remove any protective plastic films from the tile. Clean off any visible adhesive residue or grout haze.
  • Reinstall outlet cover plates, turning outlets screws vertically for a sleek look.
  • Finish by sealing backsplash seams neatly with coordinated colored grout.

With some careful planning and precision cutting, the outlets can seamlessly blend into the backsplash pattern and design.

Grouting Techniques Around Outlets

Applying grout around outlets set into backsplashes requires some finesse to keep the joints looking uniform and professional:

  • Remove the outlet covers and use painters tape to mask around the outside edges. This keeps grout off the outlets.
  • Thoroughly mix grout according to package directions. Apply evenly on joints using a hard rubber grout float.
  • Hold the float at a 45° angle and work in circular motions packing the grout into gaps. Remove excess grout.
  • Around outlet edges, switch to a grout sponge. Carefully wipe diagonally across the joints to contour grout and create smooth arcs into the corners.
  • Once grouted, run a finger around the inside outlet box edge to clean out any grout that may have oozed inside.
  • After grouting, cure times are important. Cover with plastic and allow proper set time before unmasking outlets.
  • Avoid wiping or disrupting newly grouted joints while curing or it may smear. Just remove any haze on the tile surface.

Proper grouting ensures the backsplash and outlets have a cohesive finished appearance.

Sealing Grout Around Outlets

For the best moisture resistance and easiest ongoing cleaning, seal grout lines around outlets using a penetrating grout sealer:

  • Let grout fully cure for a minimum of 72 hours after installation before sealing. This allows proper grout hardness and strength.
  • Mask outlet openings with painter’s tape to prevent getting sealer on the contacts.
  • Apply thin coats of sealer using a small applicator brush or foam paintbrush.
  • Work in sections and wipe excess sealer off tiles using a clean cloth within 5 minutes before drying.
  • Multiple thin coats are better than one heavy application to maximize absorption and avoid leaving residue.
  • Cure times between coats are usually 1-2 hours. Reapply 2-3 times for best protection.
  • Don’t use outlet for 24 hours after last sealing to allow full curing. Tape prevents premature use.

Sealing grout around outlets creates water-repellant joints that are easy to keep clean long-term with routine wiping.

Troubleshooting Backsplash Outlet Problems

Despite best efforts, issues around backsplash outlets can sometimes arise. Here are tips for troubleshooting some common problems:

Outlet Doesn’t Sit Flush

  • Remove outlet and check for proper box installation and depth. Add box extender to increase protrusion in wall.
  • Check for bulging drywall, unfilled gaps, or boogers of dried adhesive interfering with flush mounting.
  • Use a thinset mortar skim coat to level uneven areas around box before reinstalling outlet.

Backsplash Lifted or Discolored Around Outlet

  • Adhesive failure can allow moisture to penetrate behind the backsplash. Promptly replace loose sections.
  • Discoloration or staining indicates possible outlet overheating. Have an electrician inspect for loose wiring connections.
  • Outlets must be well seated and housing properly grounded to avoid intense heat buildup or arcing scorch marks.

Weeping Grout Lines Around Outlets

  • Tendency for grout to crack or leak around outlets means movement or inadequate sealing.
  • Cut out bad grout and re-grout any low spots for better moisture protection.
  • Be sure to use latex modified grout. Seal grout once fully cured.

With attention to detail during installation and proper electrical function, outlets can beautifully blend into glass backsplashes. Ongoing sealing maintains water resistance. Address any issues promptly to prevent damage or safety concerns. With the right techniques, outlets and backsplashes coexist seamlessly.
