Porcelain Tile / September 12, 2018 / Brousseau
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.
For the easiest to clean and maintain floors ceramic and porcelain tiles seem to make the most sense. In theory the specifications regarding porcelain tiles make them vastly superior to ceramic tile. The specifications state that porcelain tiles are harder and more scratch resistant than ceramic. Porcelain is supposed to be denser and less porous then ceramic. Many people like the idea that some porcelain tiles are through body where the entire porcelain tile is the exact same color and texture as the surface.
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.
