Caulk

Tools Required

Installation Steps

1. Prepare the Corner Surface

Clean the corner surface where the trim will be installed to remove any dirt or debris.

Use a notched trowel to apply a thin layer of thinset mortar to the corner area.

2. Install the Trim

Cut the outside corner tile trim to the desired length using a miter saw or tile cutter.

Apply thinset mortar to the back of the trim and press it into place against the corner.

Use a tile spacer to ensure the trim is aligned properly.

3. Level and Align

Check the level of the trim using a level. Adjust the trim as needed to ensure it is straight and level.

Use a float or spacers to align the trim with the surrounding tiles.

4. Grout the Trim

Once the thinset mortar has set, apply grout to the space between the trim and the tiles.

Use a grout float to spread the grout and fill any gaps.

5. Remove Excess Grout

Use a sponge to wipe away excess grout from the surface of the trim and tiles.

Allow the grout to set according to the manufacturer’s instructions.

6. Caulk the Trim

Apply a bead of caulk to the joint between the trim and the tiles.

Use a caulking gun to dispense the caulk smoothly and evenly.

Use a damp sponge or your finger to smooth out the caulk and remove any excess.

Finishing Touches

Remove any residual caulk or grout from the surface of the trim and surrounding tiles.

Use a clean damp cloth to wipe down the trim and give it a polished look.

Allow the caulk to fully cure before using the tiled area.

Installing outside corner tile trim is a relatively simple but important task for a successful tile installation. By following the steps outlined above, you can ensure that the trim is properly installed, protects the exposed tile edges, and adds a decorative accent to your project. Remember to work carefully and use quality materials to achieve the best results.
