Mastering External Corners: A Step-by-Step Guide to Tiling External Corners Like a Pro

External corners are the unsung heroes of any tiling project. They demand precision and care to avoid unsightly gaps or uneven edges. Whether you're renovating a bathroom or a kitchen, mastering the art of tiling external corners will elevate your work from amateur to professional. This guide will walk you through the essential techniques to achieve clean, durable corners that stand the test of time.

Before laying any tiles, the surface must be clean, dry, and level.
Start by removing any old adhesive or paint.
Use a wire brush to roughen smooth surfaces for better adhesion.
Check for levelness with a spirit level; if the wall is uneven, apply a skim coat of plaster to create a flat base.
Ensure the area is free of dust and debris.
A well-prepared surface is the foundation for a perfect corner.

For a clean external corner, you have two main options: using a tile corner bead or cutting tiles to create a mitered edge.
The bead method is simpler and more forgiving.
Apply mortar to the wall, press the bead into place, and then lay tiles against it.
Alternatively, for a seamless look, cut tiles at 45 degrees and join them at the corner.
Use a tile cutter or wet saw for precise cuts.
Always check alignment with a level and spacers for consistent grout lines.

Once the tiles are set, it's time for grouting.
Apply grout with a rubber float, working it into the joints.
Wipe away excess grout immediately with a damp sponge.
For external corners, pay extra attention to the corner joint to prevent grout buildup.
After grouting, seal the grout to protect against moisture and stains.
This step is crucial in high-moisture areas like bathrooms.
Regular maintenance will keep your corners looking pristine.

With these techniques, you can confidently tackle external corner tiling.
Remember, patience and precision are key.
Now, grab your tools and transform your space with professional-grade corners.
