How do I calculate the correct quantities of tiles to order for the area to be tiled?
When calculating the quantum of tiles you require find out the area of the surface that is to be tiled. Also establish the tiling technique and pattern such as closed joints (where the edges of the tiles touch), joints from 1/16 to 1/8 between tiles, continuous or non-continuous joints, parallel or diagonal arrangements and so on. Also remember that even a delivery of top quality tiles may contain some defective tiles. Tiles must also be cut or drilled so that a certain number will be discarded. The number that is discarded will depend on the tiling surface, especially if there are irregularities, and on the tiling techniques ( e.g. diagonal tiling creates more discarded tiles than parallel tiling). Also buy some extra tiles to save for future repairs. You should order approximately 10% more tiles than you actually need. The quantity required should be calculated carefully before the order is placed, as tiles sent in a subsequent delivery may not be identical to those of the original d
