All tiles prepared for use on floors can be installed as wall tiles. However, you cannot do it the other way around. Tiles whose specifications do not state that they can be installed on floors cannot be placed there.
The difference between ceramic and porcelain tiles basically lies in the technology used to produce both products. Porcelain tiles undergo a more demanding manufacturing process than ceramic tiles, using finer clays that make them denser and, as a result, more durable. They also have a very low water absorption rate, making them the suitable for installation as floor tiles; they are a good solution for homes and even high-traffic areas.
In turn, conventional ceramic tiles are more porous and offer less resistance, so it is advisable only to use them as wall tiles.
A rectified wall tile (REC) is a tile that has undergone an additional process in which the edge is cut at a 90º angle, i.e. with a straight edge, so that they can fit together easily. This means that each new tile has no noticeable edges so that, when they are installed, a single, even surface is created with no visible joints. A vital process for the project’s end result.
Initially, in order to calculate the number of pieces, it is necessary to calculate the surface area in square meters. However, you have to consider any cuts that will be made so that they can fit inside corners and around any other specific areas of the room. It is generally recommended to add between 5% and 7% of material in simple areas (square or rectangular), and up to an additional 15% in the case of complicated or awkward areas (with several corners that create a lot of cutting waste).
No. It is advisable for any tile being installed as exterior cladding to have a low water absorption rate, good scratch resistance, frost resistance and, in short, resistance to all harsh weather conditions.
