I've bought some split face tiles what is the best way to put these on? Do you interlock them then cut the bits sticking off, off? Hopefully this makes sense!
I think he means to do as you supposed, cut off the over-hang, but leave it rough, though I might round over the sharp edges to prevent fall against injuries.
I read it as cut the tile to length but orientate it so that the uncut end is on the corner and the cut end buts against the adjacent tile. But I could have got the wrong end of the stick.
