Porcelain Tile / June 13, 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.
The hardness of porcelain tiles is an advantage for more reasons than appearance. This quality makes these tiles far more scratch resistant than ceramic tiles. When tiles get scratched up you have to go to a lot of expense and trouble to get them polished out and sometimes even that isnt possible. Porcelain tiles are also more resistant to chipping. This hardy nature also makes them less slippery than ceramic tiles which makes them a better choice for safety reasons as well.
This ruggedness is why tiles made of porcelain are the ones most often found in floor applications for outdoor living spaces its because they are far better at handling harsh conditions. Tiles made of porcelain are practically a must for outdoor patios in cold weather climates because unlike normal ceramic tiles they are far less likely to crack. Not only can they endure the elements better but the unique absorption rate and density of means that moisture and dirt have a hard time getting through the surface. That means that the tiles look cleaner and retain their color for a longer period of time.
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.
