Flip the slate over when manually cutting the slate. When cutting slate manually with a hammer and chisel or a handheld slate cutter, flip it over and cut along the flat underside of the tiles.
Mark and cut the top of the slate when using power tools. When using power tools, it's more important that the slate lies flat on the surface you're cutting on. In this case, you'll mark the top of the slate. Use a straightedge and a pencil to mark a line. You can use a ruler or a straight piece of wood as your straightedge.
Even when using a tile saw, cutting the slate can cause it to spall. This may result in the stone producing excessive amounts of dust, particularly if you're using a dry saw. It can also result in small chips flying off the surface of the slate. Wear eye protection and a dust mask when cutting slate tiles to prevent injury from the spall. Always mark your slate prior to cutting it to ensure you are cutting the correct section.
The most effective way to mark the slate is with a grease pencil. Many slate tiles are packaged wet, which when combined with spall produces a thick mud on the tiles that is washed away during installation. Normal graphite pencils will not show up on the slate or will become washed away on the tile wet saw when the mud begins to flow.
A grease pencil will hold its mark so you can make an accurate cut each time.
