Tips and tricks:

Setting Out

Lay dry tiles on the floor and arrange so that difficult cuts and awkward corners are avoided.

How many tiles do I need?

When calculating how many tiles you need, work out how many will cover the area to be tiled – and then add 10% for breakages. You can always return the extra tiles if you don’t use them.

Cutting Tiles

For awkward cuts, it’s recommended that you make a template out of card and trace around it. Always remember to wear goggles and gloves when cutting tiles.


Use spacers to ensure regular spacing of tiles. Occasionally check with a spirit level to ensure the tiles remain level.


Occasionally lift a tile that has been recently laid to ensure full adhesive contact is being achieved.

1. Cover floor boards with 15mm thick plywood. Screw down existing wooden floors at 300mm centres through the joists.
