Porcelain Tile / August 30, 2018 / Brousseau.
For your walls or ceiling the PEI Class 1 porcelain tiles are recommended because they are not subjected to any kind of weight. The PEI Class 2 may be used as bathroom floor tiles where the weight exposure is minimal while the PEI Classes 3 and 4 are ideal as table top or kitchen top and as flooring in any part of your home. The PEI Class 5 is highly recommended for residential or commercial use where there is heavy foot traffic. Porcelain tiles are all weather tiles that can withstand heat exposure during the summer and the freezing temperatures during winter.
Identifying the Size of Hole to be Drilled. The first step is to correctly identify the size of hole to be drilled. This is very important as the diameter of the hole to be cut dictates the method that you will use to drill into the tile. The majority of holes that are 10mm and under in diameter will be drilled with the tile already fixed to the wall. Conversely the majority of holes over 10mm in diameter will be drilled into the tile before the tile has been fixed. When drilling holes that are 13mm or larger in diameter make sure that the tile to be drilled is placed in a tray that will collect the waste water that is produced.
Cheap porcelain tiles can be difficult to properly install. Cheap tiles may look nice on the surface but they may not be able to be cut cleanly with a tile saw and may chip on the edges. Also if the tiles are porous then it will be difficult to clean up the excess grout. Grout haze can become embedded in the tiles and make them look vastly different after they are installed compared to what they looked like before they were installed. Cheap tiles can have quality control issues. Many times people choose their sample tile and then order them.
Ensure that scrap tiles or another similar material is placed under the tile that is being drilled. This will help to halt the progress of the drill once it has finished drilling through the tile. Before drilling tile ensure that you are wearing the correct safety equipment including safety glasses or goggles. Ensure that you are using a residual current device (RCD) to help prevent electric shock. Drilling Small Diameter Holes (10mm or Smaller) with Diamond Cores. Mark the center of the hole to be drilled into the tile by using a marker or a sticky drive pad.
