Step-by-Step Schluter Trim Installation

This guide focuses on a general installation process. Always refer to Schluter's specific installation instructions for your chosen profile.

1. Preparation is Key

Surface Preparation: Ensure the tile surface is clean, level, and free of debris. Any imperfections will show through.
Accurate Measurement: Measure carefully. Cut the trim slightly longer than needed to allow for adjustments.
Dry Fit: Before applying mortar, dry fit the trim to ensure a proper fit and check for any needed adjustments.

2. Applying the Thin-Set Mortar

Apply Thin-Set: Use a notched trowel to apply a thin layer of thin-set mortar to the back of the trim. This secures the trim and creates a strong bond.
Even Distribution: Ensure even distribution of mortar to prevent voids.

3. Installing the Trim

Press Firmly: Press the trim firmly against the tile edge, ensuring it’s level and aligned.
Remove Excess Mortar: Immediately remove any excess mortar that squeezes out.

4. Grouting and Finishing

Allow to Set: Allow the thin-set mortar to fully cure according to the manufacturer's instructions. This is typically 24-48 hours.
Grouting: Once cured, grout the spaces between the trim and tiles, using a grout that complements the tile.
Cleaning: Clean away any excess grout with a damp sponge. Allow the grout to cure.
Caulking (Optional): For added protection and sealing, apply caulk to the areas where the trim meets other surfaces.

5. Caulking and Finishing Touches

Caulk Application: Apply a bead of suitable caulk along the exposed edges of the trim to provide water resistance and a seamless finish.
Clean Up: Carefully clean any excess caulk with a damp cloth or sponge.

Troubleshooting Common Issues

Uneven Installation: Use a level to ensure straight installation.
Cracks in the Trim: Ensure proper curing time and apply appropriate pressure during installation.
Mortar Showing Through: Clean excess mortar promptly.
