Porcelain Tile / September 6, 2018 / Brousseau.
Porcelain comes in many shapes sizes and beautiful designs. All of these characteristics seem to make porcelain the clear choice when it comes to quality durability and easy of cleaning and maintenance. In reality the truth can be vastly different. The specifications regarding porcelain tiles are never verified or tested so any manufacturer can claim that their tiles are porcelain. Tile manufacturers can claim that they are manufacturing porcelain tiles without having them tested. In many cases tiles labeled as porcelain do not have the characteristics that make them quality tiles.
Some of the more common issues that cheap porcelain tiles can have include: Cheap porcelain tiles can actually be extremely porous and difficult to clean. They will absorb all types of dirt spills and contaminates. These types of porous tiles will start to show dirty spots especially in heavy use areas and in the center of the floor where people walk. Soon your floor will look ugly and these types of deeply embedded stains are extremely difficult to clean. Often times it can help to seal these porous tiles but this can be costly and time consuming especially for a product that you thought was dense and would be easy to clean and maintain.
Drilling Large Diameter Holes (13mm or Larger). In order to cut holes that are 13mm or larger in diameter it is necessary to first drill a pilot hole. The pilot hole will act as a locater for a large diamond core and will help you to drill a perfect hole in porcelain tile. Attach an 8mm carbide drill bit or 8mm diamond bit to your drill. Follow the instructions given above for either Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores or Drilling Small Diameter Holes (10mm or Smaller) with Carbide Bits depending on whether you are using diamond cores or carbide drill bits. Leave out the final step in either case as you wont be drilling a fixing hole behind the tile.
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.
