Triangle tile trim, also known as triangle Schluter trim, is a versatile and eye-catching tile accessory that can add a touch of sophistication and professionalism to any tiled surface. Whether you’re a seasoned DIY enthusiast or a first-time tiler, installing triangle tile trim is a relatively straightforward process that can be completed in a few hours with the right tools and materials.


Before you begin, make sure you have the following tools and materials on hand:

Triangle tile trim

Tile spacers


Thinset mortar

Grout float




Measuring tape


Safety glasses


Measuring and Cutting

1. Measure the length of the area where you want to install the trim. Cut the trim to the desired length using a miter saw or a hacksaw.

2. If you need to make a corner, miter the ends of the trim at a 45-degree angle. To do this, place the trim on the miter saw table and adjust the blade to a 45-degree angle. Hold the trim in place and slowly guide it through the blade.

3. Repeat the process for the other side of the corner.

Installing the Trim

1. Apply a thin layer of thinset mortar to the back of the trim using a trowel.

2. Press the trim into place along the edge of the tile. Use a level to make sure the trim is level and straight.

3. Insert tile spacers between the trim and the tile to ensure even spacing.

4. Continue installing the trim around the perimeter of the tiled surface, making sure to miter the corners as needed.


1. Once the thinset mortar has dried, apply grout to the joints between the trim and the tile.

2. Use a grout float to spread the grout evenly over the joints.

3. Let the grout dry for 15-20 minutes, then wipe away any excess grout with a damp sponge.

Finishing Touches

1. Once the grout has completely dried, apply a sealant to the trim and the grout joints. This will help protect the trim from moisture and dirt.

2. Let the sealant dry for 24 hours before using the tiled surface.


By following these steps, you can easily install triangle tile trim for a sharp, clean finish. This simple addition can instantly elevate the look of your tiled surface, adding a touch of professionalism and sophistication to your home.
