Porcelain Tile / September 14, 2018 / Brousseau
Application of tiles are rated according to the Porcelain Enamel Institute (PEI) rating system from PEI Class 1 up to PEI Class 5. If you are looking for the right tiles to be used for your walls or ceiling the PEI Class 1 is recommended because the tiles are not exposed to any impact. You can choose the PEI Classes 2 and 3 for your bathroom tiles and the PEI Classes 3 to 5 as kitchen and tabletops and as flooring in any part of your home or building according to the impact foot traffic or exposure of the area where you will install your porcelain tiles.
It is not advisable to try and cool the drill bit by using an aspirator or drilling through a wet sponge these methods will not keep the drill bit cool enough and the drill bit will burn out. Set the electric drill to between 700 and 900 rpm. Make sure that the drill is in normal mode. Push the carbide drill bit gently into where you have marked the tile until you hear a cracking sound. Start drilling from a vertical position with sufficient pressure and dont stop until you hear a change in the tone of the drill. As soon as you hear the change in the tone begin to ease off.
These tiles offer more water resistance and frost resistance than ceramic tiles. Glazed porcelain tiles offer a surface that is resistant to wear and tear and a harder surface that is great for high traffic areas such as the kitchen or tea room. Full porcelain floor tiles have a colour and pattern that follows through to the base of the tile so the patterns are never worn away like ceramic tiles. Glazed porcelain tiles are coated with liquid glass and then baked so that the protection is impervious to wear and tear as well as stains.
