Step 1: Measure and Determine Tile Layout
The first step when tiling a backsplash is planning your layout – this is especially important around corners. Follow these tips for measuring and mapping out your backsplash tile design:
Measure the Backsplash Area
- Use a tape measure to measure the height and length of the backsplash area.
- For inside corners where countertops meet, measure both sections of the backsplash.
- Consider any outlets, switches, or obstructions and map them out.
Determine Tile Layout
- Generally, tiles should be aligned so the grout lines meet in the corner. This gives the most seamless look.
- Draw a diagram of the backsplash including measurements and corners. Map out tile placement.
- Plan the tile layout so tiles meet at the corner evenly without thin slivers. Cutting L-shaped corner tiles is ideal.
- Leave room for spacer strips which will be placed 1/8-inch from corners.
- Dry lay tiles on the countertop first to visualize placement and alignment.
Careful planning and measuring ensures your tile layout is even and corner tiles are cut to the right size. Always double-check measurements before cutting tiles.
Step 2: Install Spacer Strips
Spacer strips, also called tile edge strips, are thin strips of plastic or metal that help guide the installation of tiles around corners. Using them ensures evenly spaced tiles. Follow these tips when installing spacer strips:
- Tile spacer strips (available at hardware stores)
- Tile adhesive
- Caulk gun
- Apply a thin bead of tile adhesive along the wall just over 1/8-inch from the corner.
- Press the spacer strips into the adhesive and align them vertically, keeping the 1/8-inch space.
- Use full length strips for best results. Cut strips with tin snips to fit around outlets.
- Run strips the full height of the backsplash above and below the corner.
- Let adhesive fully cure for at least 24 hours before applying tiles.
Properly positioned spacer strips will act as guides for installing the corner tiles evenly. Don’t skip this important step!
Step 3: Measure and Cut Corner Tiles
Cutting L-shaped corner tiles is crucial for achieving a flawless finish. Follow these tips to measure, mark, and cut the tiles:
- Subway tiles for corners
- Tape measure
- Tile nippers
- Carbide tile cutter or wet saw
Measuring and Marking
- Measure from the corner to the first grout line on the tiles above and below the corner. Mark these points on a tile.
- Draw a line connecting the two marks. This will be your cut line.
- To cut an L-shape, repeat on the adjacent edge starting from the corner.
- For straight cuts, use a carbide cutter. Score the tile and snap it on the line.
- Use tile nippers to nip away small sections up to the line.
- For intricate L-shape cuts, use a wet saw fitted with a diamond tile blade. Cut along marked lines.
- Test fit the cut tile and nip/sand any uneven edges.
Measure twice and cut carefully for perfectly fitting corner tiles. Account for the 1/8-inch spacer gap when measuring.
Step 4: Apply Thinset and Set Corner Tiles
With your corner tiles cut, it’s time to adhere them. Follow best practices for applying thinset and setting the tiles:
- Notched trowel
- Thinset mortar adhesive
- Tiles, corner pieces, and spacers
- Rubber grout float
- Use a notched trowel held at a 45-degree angle to spread a thin layer of thinset adhesive on the wall.
- Apply thinset where corner tiles will go first. Leave space for the 1/8-inch spacer strip.
- Next apply thinset for the field tiles, using the spacer strips as guides.
Set Corner Tiles
- Set the pre-cut L-shaped corner tiles first, butting up to the spacers.
- Push the tiles firmly into the thinset and use light twisting motions to adhere them.
- Make sure corners align perfectly using a level. Adjust as needed before thinset cures.
- Install the surrounding field tiles next using spacers for even 1/8-inch gaps.
Take care when setting corner tiles and allow to fully cure per thinset directions before grouting.
Step 5: Grout Corner Tiles
Once the thinset has fully cured, it’s time to grout the tile joints. Follow these tips for grouting the corner tiles smoothly:
- Grout float
- Grout sealer
- Grout spacers
- Grout coloring pigment (optional)
Mix and Apply Grout
- Mix a batch of grout per package directions. Let sit 5-10 minutes, then remix before using.
- Apply grout by holding the float at a 45° angle and packing joints firmly.
- Ensure grout fills the corner seam completely. Hold float at different angles.
- Use a sawing motion across tiles to remove excess grout and smooth the joints.
- After grouting, clean tile surface with a damp sponge in circular motions.
- Once grout has cured, apply grout sealer for protection and color uniformity.
Take your time grouting the corner joints and work the grout fully into inside and outside corners.
Step 6: Add Finishing Trim Pieces
For a clean, finished look, install trim pieces along the perimeter edges once grouting is complete:
- Tile edging trim pieces
- Carbide saw with diamond blade
- Adhesive and caulk
Cut and Install Trim
- Measure and cut metal or plastic trim pieces to fit flush along the tile edges.
- For inside corners, cut adjoining pieces at a 45° angle for a tight fit.
- Apply small beads of construction adhesive along the trim piece edges.
- Set trim snugly against tile edges. Temporarily secure with painter’s tape until adhesive cures.
- Caulk along seams with a silicone caulk that matches the grout color. Tool smoothly.
Trim molding gives a polished, professional look to the subway tile backsplash installation.
Step 7: Final Cleaning and Sealing
As a final step, thoroughly clean and seal the grout and tiles:
- Once grout has fully cured, use a grout haze remover or mix vinegar and water to clean residual haze or film.
- Scrub entire tiled area with cleansing solution using a soft brush or sponge.
- Rinse several times with clean water and dry with a cloth.
- After tiles are clean and dry, apply a penetrating sealant using a foam paintbrush.
- Work sealant fully into the grout lines for maximum protection.
- Wipe off any excess sealant after 5-10 minutes with a clean cloth.
Allow sealant to cure fully before using the backsplash. Enjoy your stunning, professionally finished subway tile backsplash!
