DIY Tips – Tiling corners
Thursday, September 29th, 2011The real problem when it comes to tiling internal corners is that they are often not perfectly square. This means that tiles have to be cut away slightly to allow for the geometric defects in walls. A convenient way of doing this is to measure the gap at the bottom and the top and use this result to angle the cut for the tiles.
Another method is to place the tile you are about to cut on top of the last whole tile in a row, and hold a third whole tile on top of this with one of its edges pressed into the corner. Then you can use the top tile’s opposite edge to draw the line of the necessary cut.
External corner tiling is also complicated by the fact that walls are typically not perfectly square. The problem with external corner tiling, however, is a bit trickier than with internal corners. This is because you need to hide the unglazed edges of the cut tiles.
The way to achieve this is to cover one wall with the tiles cut to fit in the normal way. The cut tiles which then start the other wall are then placed so that they overlap those on the first one. The exposed cut edge is then covered with tiling grout. The finish can be made even neater if you begin the second wall with whole edging tiles. However, the walls have to be perfectly vertical in order to do this, which is usually not the case.
