Porcelain Tile / September 10, 2018 / Brousseau
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.
Unglazed tiles do not have a coated surface and full body porcelain tiles dont show wear anyhow due to the colour and design being throughout the entire tile. These types of tiles have a PEI rating of 0-5 meaning they can be used in any area. PEI classes are 0 through 5. The porcelain enamel institute scale is one that is used to help detect areas that tiles should be used in. The glazed tiles that have the overall 0 to 5 rating can be used anywhere from no foot traffic to industrial traffic making them ideal for use in your home.
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.
