Floor tile installation is a job for professionals or DIY enthusiasts who are very competitive because it usually requires special equipment and some skill to make it look perfect. Placing a square or rectangular tiles may seem relatively easy but the difficulty arises when the tile to be cut (as they always do) and formed around obstructions in the room.
Cutting tiles is as hard as porcelain floor tiles or some types of natural stone that can only be done by professional equipment. It is possible to hire the right equipment but can be costly and there is still the risk of damaging expensive porcelain tiles with pieces that bad. Professional floor tilers are there for a reason. You can get help from an expert tiling service in Perth to get your job done successfully.
If you are confident enough to install your own floor tiles, or if you have used a professional tiler, the most important thing to do first is to prepare the surface on which to place the tile. If the existing floor is concrete then the work will be fairly easy – a mortar can be applied directly to the floor and tiles placed on top.
If the floor is made of wood, the solution is less simple – a cement backer unit (CBU) used with a moisture-resistant membrane is a good choice for substrate wall tiles in wet areas and is often also used to strengthen floors and provide a moisture barrier between tiles and wood underneath it.
