How to Install Signal Cornish Slate Tile on Walls

Quick Answer

To install Signal Cornish Slate tiles on walls, prepare a flat, clean surface, apply a suitable adhesive with a notched trowel, press each tile firmly with spacers, and finish with grout once the adhesive cures.

Step-by-Step Installation Guide

1. Prepare the Surface: Clean the wall thoroughly, removing any dust, grease, or loose paint. Fill any holes or cracks with filler and sand smooth. If the wall is very uneven, apply a leveling compound and allow it to dry completely. A smooth, clean surface is essential for a strong adhesive bond.
2. Plan Your Layout: Measure the wall and mark the center point. Dry-lay a row of tiles on the floor to plan your cuts and ensure a balanced layout. Use a chalk line to mark vertical and horizontal reference lines. Always start from the center and work outward to avoid small, awkward cuts at the edges.
3. Mix and Apply Adhesive: Choose a suitable tile adhesive for natural stone or slate tiles. Mix according to the manufacturer's instructions. Using a notched trowel, spread adhesive onto a small section of the wall, holding the trowel at a 45-degree angle to create even ridges. Work in small areas to prevent the adhesive from skinning over before you place the tiles.
4. Set the Tiles: Press each tile firmly into the adhesive with a slight twisting motion to ensure full contact. Insert spacers between tiles to maintain even gaps. Use a spirit level to check alignment periodically and adjust as needed. Check for lippage (uneven edges) as you go; adjust tiles immediately before the adhesive sets.
5. Cut Tiles to Fit: For edge and corner tiles, measure and mark the cut line. Use a manual tile cutter for straight cuts or an angle grinder with a diamond blade for notches and curves. Always wear safety goggles and a dust mask. Cut tiles slightly larger than needed and dry-fit before applying adhesive to avoid costly mistakes.
6. Allow Adhesive to Cure: Leave the adhesive to cure for at least 24 hours, or as recommended by the manufacturer. Do not disturb the tiles during this time. Patience here prevents tiles from slipping or bonding poorly.
7. Grout the Joints: Remove the spacers and mix grout according to instructions. Using a rubber float, spread grout diagonally across the joints, pressing it in firmly. Wipe off excess with a damp sponge before it hardens. Work in small sections and clean the surface promptly to avoid a hazy residue.
