DIY steps
- Shut off power to any outlets or switches in the area, and cover the countertops and floor with drop cloths to protect them from dust and debris. Wear protective eyewear, gloves, and a dust mask to prevent injury. Begin by cleaning the wall thoroughly with a degreaser to ensure a strong bond between the tile and the wall.
- Apply a layer of thinset mortar to the wall, holding the notched trowel at a 45-degree angle to spread it evenly. Use a level to ensure the mortar is straight, and a putty knife to fill in any gaps or holes in the wall.
- Begin installing the mosaic tile sheets, starting from the center of the wall and working your way outwards. Use a rubber mallet to tap each sheet into place, ensuring they are level and plumb. Use spacers to maintain even grout lines.
- Once all the tile sheets are in place, allow the thinset to set for 24 hours. Then, mix the grout according to the manufacturer's instructions and apply it to the tile using a grout float. Hold the float at a 45-degree angle to press the grout into the gaps between the tiles.
- Use a damp sponge to wipe away excess grout from the surface of the tiles, changing the water frequently to prevent the grout from spreading. Allow the grout to set for 24 hours before sealing it with a grout sealer.
- After the grout has set, inspect the tile installation for any gaps or unevenness. Use a grout saw to make any necessary adjustments, and apply additional grout as needed.
- Clean the tile and grout with a mild detergent and water, and allow it to dry completely before applying a grout sealer.
