If you’re planning a tiled project involving external corners, proper installation of corner tile trim is essential for a professional and polished finish. Here’s a comprehensive guide with expert advice, tips, and tricks to help you successfully install external corner tile trim:


1. Gather necessary tools and materials: Before starting, ensure you have all the necessary tools, including a wet saw, miter box, trowel, level, grout float, and corner trim pieces.

2. Clean the surface: Thoroughly clean the surface where the tile trim will be installed to remove any dirt or debris that could affect adhesion.

3. Measure and cut the tiles: Measure the length of the external corner and cut the tiles accordingly using a wet saw. Ensure the cuts are precise and clean.

Installing the Corner Trim

1. Apply thin-set mortar: Spread a thin layer of thin-set mortar along the corner where the trim will be placed using a trowel.

2. Press the trim into place: Carefully align the corner trim and press it into the thin-set mortar. Ensure it’s level and straight.

3. Fix with screws: If desired, use screws to secure the corner trim in place. This step is recommended for added stability.

Finishing Touches

1. Grout the joints: Mix grout according to the manufacturer’s instructions and apply it to the joints between the trim and tiles. Use a grout float to smooth the surface.

2. Clean excess grout: After the grout cures slightly, use a damp sponge to clean excess grout from the surface.

3. Seal the trim: Apply a sealant to the trim and surrounding grout to prevent moisture penetration and staining.

Tips and Tricks

1. Use a miter box for precise corner cuts: A miter box ensures precise 45-degree cuts for a perfect fit.

2. Back butter the tiles: Apply thin-set mortar to the back of the tiles before setting them into the trim to improve adhesion.

3. Use spacers for even spacing: Place spacers between the tiles and trim to ensure consistent spacing.

4. Cure the grout properly: Allow the grout to cure thoroughly before using the tiled area to prevent cracking or damage.

5. Protect the trim during installation: Use masking tape or protective film to prevent accidental scratches or damage to the trim during installation.

By following these expert tips and tricks, you can successfully install external corner tile trim for a professional and aesthetically pleasing finish. Remember to approach the task with patience, precision, and attention to detail for optimal results.
