Installing a tile backsplash can add style and visual interest to your kitchen or bathroom. While tiling most of the backsplash area is relatively straightforward, finishing the edges where the tiles meet the countertops, cabinets, and walls takes some extra planning and technique to get a professional-looking result. Proper finishing is important both for appearance and to protect the tile edges from cracking or chipping over time.

Preparing the Tile Edges

Before installing any tiles, take time to carefully prepare the edges and transition areas. Rushing this step can lead to a sloppy final look.

Select Edge Pieces First

Pick out the tiles you plan to use along the edges first. Often these are cut pieces or trim tiles designed to finish an edge. Choose options that complement both your main tile and the countertops/cabinets they will meet. Common choices include:

Bullnose tiles: Rounded or sloped finish; softer look.
Pencil tiles: Narrow rectangular tiles placed vertically.
L- or U-shaped tiles: Offer a clean finish on inside/outside corners.
Decorative trim: Specialty mosaic, patterned or artistic edge tiles.

Mixing bullnose and pencil tiles or using deco trim on the top and bottom edges can add extra interest.

Measure Carefully

Take detailed measurements of all transitions and edges before cutting any tiles. Mark the measurements on the tiles chosen for those areas. This allows you to cut them to the perfect size and shape the first time. Trying to trim tiles down after installing almost never works.

Cut Tiles and Test Fit

Cut all edge and decorative trim tiles to size before installation day. Make sure they fit as intended where they will be placed. Adjust and recut as needed for a flawless fit.

Account for Gaps

When tiling up to cabinets, walls, etc. you need extra room for tile spacers and grout lines. Determine the size of your grout joints ahead of time, then add that measurement to the edges of any surface where the tile will end. This ensures no unsightly gaps are left between the tile edge and the wall or cabinet.

Installing Bullnose and Pencil Tiles

Bullnose and pencil tiles create clean finished edges along countertops, niche openings, and vertical edges:

Bullnose Tiles

What they are: Tiles with one finished, rounded edge. The round edge often has a decorative pattern or tone that complements the main tile.

Where to use: To finish outside tile edges along countertops, walls, niches and shelves. Softens the transition from tile to countertop.

How to install:

Bullnose tiles should be cut to fit the entire perimeter edge.
Place bullnose tiles first so the body of the tile overlaps the edge just slightly.
Match bullnose grout lines with main tile grout lines.
Take care not to crack or chip the finished bullnose edge when setting tiles or applying grout.

Pencil Tiles

What they are: Thin, narrow tiles designed to stand upright along vertical edges and transitions.

Where to use: Finishing edges where tile meets cabinets, walls, electrical boxes, plumbing fixtures, etc.

How to install:

Measure and cut pencil tiles to exact height needed.
Apply trim tiles vertically, keep plumb and align with main tile grout lines.
Use tile spacers to leave appropriate gaps.
Match grout color and texture with main field.

Using Trim Pieces

Trim pieces include corner accent tiles, listellos, mosaics and other decorative strips. These can be used to dress up transitions and edges throughout the installation.

Types of Trim

Corner trim – Specialized pieces to finish inside/outside corners neatly. Often L-shaped.

Listellos – Thin dimensional tiles or mosaics installed vertically as accents.

Decorative strips – Borders, geometric mosaics, ornate styles to accent edges.

Chair rail trim – Finished mid-wall trim piece, popular for shiplap looks.

Other unique designs – Skinny subway tiles, combinations, patterns.

Where to Use Decorative Trim

Trim tiles highlight these types of edges:

Countertop to backsplash transition
Outside vertical edges
Inside corner where backsplash meets wall
Niches and shelving openings
Chair rail mid-wall accents
Backsplashes with shiplap or geometric patterns
Open shelf dividers

Mixing multiple trim styles (listellos, mosaics, bullnose) creates extra interest.

Installing Trim Tile Accents

Measure carefully and cut tiles to fit each space precisely.
Typically installed vertically. Keep lines crisp and grout gaps even.
Match grout lines between trim and main tiles.
Take care not to crack brittle mosaics or intricate edges.

Grouting Tile Edges

All tile edges need to be grouted for a water resistant, professional finish. Take steps to prevent cracking or chipping during this process:

Grout Type

Choose an appropriate grout. Unsanded grout is better for thin grout lines and delicate tiles. Sanded grout for wider joints. Match grout texture and color with the main field.

Grout Lines

Be consistent with grout line spacing, especially on visible edges. Keep lines straight and even.

Applying Grout

Work the grout carefully into trim edges with a grout float vs. a stiff grout sponge. Take care not to dig into the tile edges.

Curing and Sealing

Follow all manufacturer instructions for curing times. Seal grout once fully cured, using a grout sealing product compatible with your grout type.

Grout Maintenance

Check for cracks and re-seal grout along edges twice a year. This prevents moisture from penetrating behind tiles and compromising adhesion.

Cutting Difficult Tile Edges

Some edges in your backsplash may require making precise cuts on fragile tiles or intricate shapes:

Tools for Cutting Tile

Wet tile saw – Creates clean, smooth cuts through tile and stone. Ideal for most edges.

Tile nippers – Quick small bites for curves, notches, short cuts.

Rod saw – For detailed contours. Jewelers saw works on tiny mosaic pieces.

Grinder – Fitted with diamond blade for tile; use with water to prevent chipping.

Manual score and snap cutter – For straight cuts in soft tile; not all models can cut thick tile.

Unique Cuts

Detailed contours – Mark shape on tile first. Use rod saw or grinder to carefully follow lines.

Curves – Mark the curve. Use grinder or nippers and shape as you cut. Test fit often.

Notches – Mark and create the notch with tile nippers, grinder or wet saw.

Holes – Detailed openings for plumbing, etc. Drill a pilot hole first, then use nippers to shape.

Preventing Chipping

Go slow with intricate cuts; don’t rush delicate tiles.
Keep water flowing when using a grinder or wet saw.
Support thin or fragile tiles fully when scoring and snapping.
Use painter’s tape on glazed tile surfaces when cutting to prevent chipping.

Edge Options by Tile Type

Certain tile shapes and materials work best with specific edge treatments:

Subway Tile Edges

The thin rectangular shape dictates edge options:

Stacked or staggered brick pattern layout.
Pencil tiles to finish vertical ends.
Bullnose tiles along countertops.
Listellos to border niche openings.

Glass Tile Edges

Fragile material requires care when cutting:

Smooth bullnose or trim tiles are safest edge choice.
Use a wet tile saw with steady water flow when cutting.
Support the tile fully to prevent cracking when scoring.
Rod saw can create detailed shards and contours.

Porcelain, Ceramic and Stone Edges

Tough materials allow versatility in edge finishing:

Bullnose, pencil tiles, listellos all suitable.
Intricate cuts can be made with grinder or wet saw.
Honed stone edge makes a soft counter accent.
Match the visual style – rustic, modern, sleek, etc.

Mosaic Tile Edges

Tiny pieces need special treatment:

Extreme care cutting fragile bits. Use rod saw.
Finish edges with coordinated mosaic strips.
Use mesh-backed sheets for easier installation.
Grout very carefully to avoid digging out tiles.

FAQ About Finishing Tile Backsplash Edges

What are the best tiles for finishing a backsplash edge?

Bullnose, pencil tiles, L-trim and specialty accents like listellos or mosaics make excellent edging for backsplashes. Choose materials and colors that coordinate well with your main field tile.

How do I measure for bullnose tiles?

Measure the entire perimeter edge where you want bullnose tiles to finish. Mark measurements directly on tiles, including any gaps needed for grout lines and spacing. Cut tiles precisely to fit each marked measurement.

Should tiles or bullnose go first when edging a backsplash?

Install any bullnose or trim tiles first around the perimeter before setting the main field tiles. This allows the bullnose to overlap the field tile edges slightly for a finished look.

What’s the best way to cut curved tiles?

Mark the shape on the tile first. Use a grinder or tile nippers to cut small sections, working gradually around the curve and test fitting as you go. Cutting in increments allows you to fine tune the curve for a custom fit.

How do I prevent chipping when cutting tile?

Always keep water flowing over the tile when using a wet saw or grinder to eliminate chipping and overheating. Support the tile fully when scoring, snapping or nibbling away sections. Use painter’s tape on glazed tile before cutting to prevent flaking of the surface.

Can I use sanded grout on glass tile edges?

It’s best to use unsanded grout only with glass tiles. Sanded grout can scratch the smooth glass and work behind tiles, causing cracks. Match the grout color with your main field.

What’s the easiest way to finish cut outs for outlets?

Measure the opening precisely. Use a grinder or tile nippers to cut small sections working gradually inward to the line. Or make two straight cuts with a wet saw, then nip out the center piece. Finish the edges with matching trim.

How do I finish thin tiles on inside corners?

Use specialty L-shaped trim tiles to create a clean finish on inside corners. Measure exactly and cut to size. Alternately, miter cut the thin tiles at a 45 degree angle to overlap cleanly.

Conclusion

Installing a tile backsplash brings an eye-catching focal point to your kitchen or bath. While the field tiles make up the main impact, dedicating proper care and precision to the finishing edges truly elevates the entire design. The right edge and trim pieces, smart cuts, careful grout work, and consistent detail will ensure your new backsplash looks like a work of art. With some planning and patience, you can achieve striking finished edges that complete your tiled space in style.

How to Finish Tile Edges on a Backsplash

Select the Right Edging Tiles

Pick out the specialty tiles you’ll use to finish the edges first. Consider bullnose tiles, which have a rounded finish for a softer look. Pencil tiles are thin and rectangular to place vertically along edges. Use L-shaped tiles on inside corners. Decorative trim like mosaics or metal can dress up edges as well. Mix and match materials for extra interest.

Measure Carefully

Take detailed measurements along all edges before cutting any tiles. Account for the spacing you’ll need for grout lines. Mark all measurements directly on the tiles. This allows you to cut them perfectly the first time.

Cut Tiles and Dry Fit

Cut all specialty tiles to size before installing. Make sure tile edges fit right against walls, cabinets, and counters when dry set. Adjust and recut as needed for precision.

Install Bullnose and Edge Tiles First

Adhere bullnose, trim, and pencil tiles around the entire perimeter before setting the main field tiles. This allows the edges to overlap slightly for a finished look.

Consistent Grout Lines

When grouting, keep lines the same width for a consistent look. Take care not to crack tile edges by applying grout too forcefully.

Unique Cuts
