Installing tile edges, also known as tile trim or molding, is an important finishing step when tiling floors, walls, kitchens, bathrooms, and more. Properly finishing the edges of newly laid tile gives a space a clean, polished look. Tile edging also serves the practical purpose of protecting the tile edges themselves from chipping and cracks. With so many options to choose from – metal, vinyl, bullnose, and more – how do you pick the right tile edging for your project?
We’ll also look at choosing the perfect edge finish based on your tiling material, design style, skill level, and budget. Read on to learn everything you need for flawless tile edge results.
Types of Tile Edges and Trims
Tile trims and edges come in a variety of materials, shapes, and sizes. Some offer decorative finishes while others focus more on functionality and protection. Choosing the right option comes down to the look you want and how the trim will interface with your tile type. Here are some of the most common tile edge profiles to consider:
Metal Edging
Trim pieces made of metal, usually aluminum or stainless steel, provide a clean, contemporary finish. The sleek, minimalist look works well for modern styles. Metal edges are easy to cut and install. They’re durable, water-resistant, and great for protecting the edges of glass tiles and stone. On the downside, metal can be prone to dents and scratches. It also tends to have a higher price point than vinyl or plastic trim.
Plastic/Vinyl Trims
Plastic and vinyl are affordable, flexible trim materials that come in a range of profiles. Common options include:
- Quarter round – Small rounded trim placed where the tile meets the wall
- Bullnose – Tile with rounded finished edges
- Cove Base – Rounded “cove” shape fits between tile and wall
Vinyl trim is water-resistant and provides good protection for tile corners. It’s easy to work with using basic tools. On the downside, plastic and vinyl can warp, crack, or fade over time with exposure to sunlight and moisture.
Wood Trims
For a classic finish, wood trim brings a touch of elegance. Common wood trim profiles include baseboard, quarter-round, and shoe molding. Wood matches traditional decor and warms up tile installations. However, moisture can damage or warp wood over time. It requires extra sealing and maintenance. Wood also costs more than basic plastic or vinyl options.
Tile Bullnose
Bullnose refers to tiles that have rounded finished edges. Bullnose tile is a single piece made to have a smooth, finished edge, not a separate trim strip added later. The rounded profile has no hard edges that can chip or crack. Bullnose tile is made from the same material as your floor or wall tile for an integrated look. The rounded shape is made during manufacturing by grinding and polishing.
Bullnose is ideal for finishing outside tile corners and eliminating grout lines. It can be pricey if not using a tile already with bullnose options. Extra grinding and shaping work is required during installation to get clean cuts.
Specialty Profiles
In addition to the standard shapes above, some unique tile edge trim options include:
- V-Cap – Rigid vinyl or metal edging with a V-shaped lip
- Pencil Liner – Thin, narrow trim for minimal distinction between surfaces
These specialty trims serve specific design purposes, like capping backsplashes or transitioning between tile and carpet. They can provide contemporary or industrial edge looks.
Plan Your Tile Edging
Once you’ve selected the type of tile edge trim to use, planning is essential for a streamlined installation. Here are some tips:
Measure Carefully
Take detailed measurements of all your tile edges needing trim. Include inside and outside corners. This lets you calculate exactly how much trim material to purchase. Trying to piece together uneven trim segments leads to uneven lines and sloppy finished edges.
Order Extra Trim
Purchase 10-15% more trim than your measurements indicate you’ll need. Having spare pieces allows you to discard damaged trim sections or replace future cracks/damage. It also covers mistakes in cutting.
Match Trim Style to Tile Type
Select trim that suits the tile design and material. For natural stone tiles, metal or bullnose trim complements the veining and pattern. Mosaic tiles pair well with thin pencil liner strips. Make sure grout color also aligns with the trim color.
Cutting and Installing Tile Edge Trim
Proper tile trim installation results in flush edges and crisp lines. Follow these best practices:
Cutting Tips
A miter saw with a fine-tooth blade makes straight, clean trim cuts. For bullnose edging, use a tile wet saw or router. A 45-degree mitered joint ensures tight seams at corners. Go slowly and steady your hands when cutting to avoid mistakes.
Tools Needed
Have ready a tape measure, pencil, level, tile cutter, snips, and drill. For installation, use a caulk gun, non-sanded grout, mixing bucket, sponges, painters’ tape, and rags.
Install Trim Last
It’s best to install trim pieces after grouting is complete. This allows the trim to sit flush along the finished tile surface. Grout filler can stain trim if installed beforehand. Leave edges exposed until tiling and grouting is done.
Step-by-Step Installation
- Thoroughly clean the tile edge surface and trim pieces, removing any dirt or residue.
- Measure and cut trim to required lengths using a power miter saw and carbide blade.
- Apply a heavy bead of construction adhesive to the back of the trim piece using a caulk gun.
- Press trim firmly into place along the tile edge. Use painter’s tape to hold trim steady if needed.
- Use a damp sponge to immediately wipe away any excess adhesive.
- Allow adhesive to fully cure for 24-48 hours before grouting seams.
Tips for Corners and Outlets
Take extra care when cutting and fitting trim around inside/outside corners and electrical outlets. Use a miter saw to cut precise 45-degree angles for seamless corners. For outlets, measure and notch out trim as needed for cords to feed through.
Grouting and Caulking with Trim
Finish off tile trim installation by filling any gaps and sealing seams:
Use Caulk, Not Grout, Along Seams
Apply a flexible silicone caulk, not grout, along joints where trim meets the tile. Unlike rigid grout, caulk allows for expansion and contraction and prevents cracking.
Fill Any Gaps
Inspect trim edges and use caulk to fill any visible gaps or imperfections. Tool the caulk smooth with a moistened finger for a neat finish.
Smooth Caulking Techniques
For clean caulk lines, go slowly and steady your arm. Hold the caulk gun at a 45-degree angle and maintain consistent pressure as you apply. Use a dampened fingertip to smoothly spread and shape the caulk, wiping away excess.
Caring for Tile Edges
Show tile edges some TLC and they’ll stay beautiful and protected:
Regular Cleaning
Use mild soap and water to keep tile edges free of grime. Pay extra attention to caulk lines and crevices where grease can gather. Avoid harsh cleaners that may damage finishes.
Replacing Damaged Trim
If trim cracks, warps, or becomes damaged, carefully pry it off and replace it with new pieces. Match the trim style and color as closely as possible for a consistent look.
Preventing Cracks
Insulating exterior walls and allowing new installations to fully cure reduces temperature fluctuations that can cause cracking at trim joints. Keeping the overall humidity level stable in a room also prevents moisture damage.
Choosing What’s Right for You
With all of the options available, keep the following factors in mind when selecting tile edge trims for your particular tile project:
Match Trim to Tile Material
Trim made from a similar material as the tile itself provides design cohesion. Natural stone works well with metal edges, while porcelain pairs nicely with vinyl.
Consider Your Skill Level
Beginners may want to start with user-friendly vinyl or plastic trim that’s forgiving to cut and install. Bullnose and metal edges require more precision.
Think About Costs
Vinyl and plastic trim is the most budget-friendly. Wood and metal trims have a higher price tag. Specialty profiles and some colors also add to costs. Plan accordingly based on your overall budget.
Installing trim and edge profiles is a finishing touch that can make or break the look of a tile installation. With the right materials and some careful planning, cutting, and installation, it’s easy to add beautiful, durable edges to accent your tiles.
The many trim designs available offer endless options for protecting corners, transitioning floors, and showcasing your unique style. Trim transforms basic tiles into a polished, pulled-together look. Just take care to properly maintain and clean finished edges so your handiwork stays pristine for years of enjoyment.
