Mirrored walls add the illusion of space to a room, but the larger the mirrors used, the greater the expense. Along with the high costs, large plate-glass mirrors can be difficult to self-install because of their weight. An alternative to plate-glass mirrors are mirror tiles. Though the installation is similar to other types of tile, you will need specialised glue to mount mirror tiles into place.
Measure the wall surface where you'll install the tiles. Mark the surface to be covered with chalk.
Remove any backing material placed on the wall, including wallpaper or panelling. If the wall has been painted with a glossy paint, lightly sand the surface of the paint to remove the gloss finish.
Create an outline of the tiled surface using a chalk line. Attach one end of the chalk line to a marked corner and extend the chalk to a neighbouring corner, using a carpenter's level to make sure the chalk line is plumb or level. Hold the line at the new corner and raise it slightly from the surface. Release the line so that it snaps against the surface of the wall, leaving a visible line of chalk to serve as a guideline for your mirror tile placement. Use the same process to chalk out the other lines surrounding the instalment area.
Determine the number of tiles needed to cover the surface by dividing the total area of the surface by the size of the tiles. Partial wall tiles may be required for edge placements. To cut the tiles to fit, use a glass cutter.
Place a layer of mirror mastic on the wall to serve as the tile glue. The mirror mastic is created to act as an adhesive for mirrored objects It lacks chemicals placed in other mastics which could react adversely with the reflective backing material of the mirrors. Press the tiles firmly to the wall, using a slight twisting motion to aid the mastic in gripping wall textures.
Lay the mirror tiles in a row, beginning at the centre-[bottom edge of the marked surface and working your way to the sides. Stop placement of the tiles when you reach the area where partials are required and begin laying the next row of tiles, working your way upwards. Butt the edges of the tiles together to form a tight seam between the tiles.
Cut and place partial tiles. By beginning your tile placement in the middle you ensured that the partial tiles on both sides of the full-tile placements are evenly sized for a symmetrical appearance to the wall. Set partial tiles so that cut edges are placed away from the full-sized tiles.
Finish the tile placement by gluing a framing strip along the outside edge of the mirror tiles to protect the edges from damage.
Glued mirror tiles cannot be removed without damaging either the tiles or the wall. If adjustments are necessary, make them immediately before the glue has set.
