Measure the length of the ledge where your mosaic tiles will be and mark the centre point as a reference, so that you can lay up your tiles symmetrically.
From the centre point of the ledge, lay down a sheet of tiles and move it along the ledge to work out how many sheets of tiles you'll need.
Lay a sheet of tiles on the ledge to mark how wide they need to be. With your safety gloves on, cut all of the sheets of tiles to the right width with a utility knife.
Line up the sheets of mosaic on the wall so that they match the sheets on the ledge, which will ensure that you get a symmetrical look.
While measuring, take into account any obstructions, like a water outlet, and mark where it lines up on your tile(s). To cut the tile, pull it away from the sheet. Put on your gloves and cut the tile with your tile nippers.
Using the spirit level, draw a line down from the centre of the ledge. This will be your reference point to work out how many tiles you need and keep them symmetrical.
Working from the centre, place your sheets of tiles onto the adhesive, and place any cut tiles back in their place.
If you come across a large obstruction in the wall, like a mixer tap outlet, you'll need to cut space in your tiles to accommodate it. Line your tile sheet up next the outlet and mark it's position and size on your tile sheet.
Using the spirit level, transfer your marks into the correct position on the tile sheet and mark them up with your pencil. Then use the angle grinder to cut a hole in the tiles. Make sure that you wear your safety gear.
Lay any cut tiles into place over their obstructions, and continue tiling the rest of the wall. Use the rubber grout trowel to press the tiles down and also check that it's level before the adhesive dries.Once you've finished and the tiles are dry, the next thing you need to do is add some grout to complete the look.
