Finishing the edges of a tile backsplash is an important final step that can make or break the look of your backsplash. With some planning and the right materials, you can achieve a clean, polished look for the edges of your backsplash tile. Here is a comprehensive guide on how to professionally finish the end of a tile backsplash.
Select an End Cap Material
- Bullnose tiles – These tiles have finished rounded edges that provide a clean finish. They match the field tiles and give a cohesive look.
- Metal strips – Brushed metal, copper or stainless steel strips act as trim and protect the tile edges. They add style and visual interest.
- PVC or vinyl – Inexpensive PVC trim pieces come in matching colors. Use caulk to attach them for a watertight seal.
- Natural stone – Matching stone strips like marble give an upscale finished look. Select polished stone for a clean edge.
- Glass – Clear glass tile trim or colored glass accent strips make for a unique end cap. The glass must be cut to fit.
Prepare the Surface
Before installing end caps, the edges of the tiles must be prepared properly:
- Remove any existing caulk or debris with a utility knife. Scrape and sand the edges smooth.
- Use a level to ensure the tiles end in a straight line if the wall is uneven.
- Cut any bump outs or uneven tiles with an angle grinder. Grind the edges smooth.
- Wipe away all tile dust and debris before applying end caps for maximum adhesion.
Measure and Cut End Caps
Take detailed measurements of the backsplash length to cut end cap pieces to size:
- For bullnose tiles, measure the length and have tiles cut to size. Leave a 1/8” gap between pieces.
- Metal strips should overlap corners by at least 1”. Have them cut slightly longer than needed.
- Vinyl pieces can be cut easily with tin snips. Leave a 1/4” gap at corners for caulk.
- Natural stone can be cut with a wet saw or scored and snapped with pliers.
- Use a glass cutter for glass tiles. Grind cut edges smooth with wet sandpaper.
Adhere the End Caps
Install end caps using the appropriate adhesive for each material type:
- Bullnose tiles – Use thinset mortar to adhere bullnose tiles. Push them into the mortar firmly.
- Metal strips – Construction adhesive works best for metal strips. Apply adhesive and press strips firmly in place.
- Vinyl – Use clear silicone caulk to affix vinyl caps. Run a steady bead and press caps on.
- Natural stone – Mortar adhesive or construction adhesive both work to install stone caps.
- Glass – Use clear silicone adhesive to install glass end caps and prevent cracking.
Finish With Caulk
Finish the end caps with a waterproof caulk suitable for kitchen and bath use:
- Use a caulk that matches the color of the end cap material for a invisible finish.
- Load caulk into a caulk gun and cut the tip at a 45° angle for better control.
- Run a steady bead of caulk along the seams and gaps around all edges.
- Wet your finger and use it to smooth the caulk into a uniform finish.
- Wipe away any excess caulk with a damp cloth for clean lines.
- Allow the caulk to fully cure for 24-48 hours before exposure to water.
Questions and Answers
What is the easiest end cap material to install for beginners?
For DIY beginners, flexible PVC/vinyl end caps are the easiest material to install. They don’t require special tools to cut, can be adhered with simple caulk, and any gaps can be filled with caulk for a finished look.
What is the best end cap option for a stone tile backsplash?
For natural stone tiles like marble, travertine or granite, matching stone end caps give the most seamless, high-end look. Bullnose tiles that match the field stone are also an excellent option.
Should you caulk the seams between end cap pieces?
Yes, you should run a bead of caulk along the seams between bullnose tiles, vinyl pieces or any other end cap material. The caulk seals gaps, prevents moisture intrusion and gives a polished finish.
What tool do you use to cut metal end caps?
Metal end caps should be carefully measured and cut to size using a hacksaw or metal snips. You can also have strips custom cut to size at most hardware stores if you provide the measurements.
Can you use wood trim to finish tile backsplash edges?
Wood trim is not recommended. It can warp from moisture exposure. Tile end caps or waterproof vinyl are better options that stand up to water and humidity in kitchens.
Conclusion
Installing end caps is an essential finishing step for a polished, professional-looking tile backsplash. With proper planning, accurate measuring and cutting, and careful installation, you can create durable, beautiful edges for your backsplash project using bullnose tile, metal, stone, vinyl or glass end caps. Taking time to properly prepare the tile edges, adhere the caps, caulk the seams, and allow proper cure time will help your finished backsplash withstand moisture and everyday use for years to come.
