Porcelain Tile / September 7, 2018 / Brousseau.
Now that the pilot hole has been cut it is possible to drill the main (large) hole. Attach the appropriate diamond core and ensure that there is a constant supply of cold water (see water cooling information in the previous sections of this article). Diamond cores that are larger than 13mm will require an adapter with pilot pin that locates into the pilot hole that has been cut previously to ensure the perfect hole will be made. Starting the drill vertically begin to drill in a circular motion with sufficient pressure until the tone of the drill changes.
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.
Porcelain tiles may be classified into natural glazed and polished tiles. The natural porcelain tile normally does not undergo any further finish after it is exposed to high temperature. This type of tile may be referred to as unglazed or through body tile where the colour goes all the way through. The glazed tile is coated with liquid glass that allows the manufacturer to put in a variety of designs and play around with colours. It comes out glossy and is one of the easiest to maintain. They are highly recommended as walls or accents in bathrooms and kitchen.
When the shipment arrives they can look vastly different from the ones that were originally ordered. Often the colors and textures can look different from the sample. Other times there may be surface scratches or other imperfections that make them look ugly. Once the shipment arrives at your door it can be extremely difficult to return them and ship them back. Other times the quality control issues are not noticed until the tiles are installed and then the manufacturer will never accept returns on already installed tiles no mater what types of problems they have.
