Bought some mosaic stone/glass back splash sheets to install in

thick. Would hate to buy a saw, never to use it again. Thanks.

Hey, my wife and I are doing exactly this. Must be a new-year get-it-done bug.

We have a cheap wetsaw--literally the cheapest on the shelf at Home Depot--and it works brilliantly on the stone and glass mosaic. The glass cuts like butter and the stone is no problem. I recall this saw being on sale for like $50 and we're using a generic blade that we got for ceramic bathroom tile. I recall that tile being slower to cut.

For long straight cuts, like evening the edge, I left it on the backing. Since the saw table is too small to hold it flat, I just rolled it up and held it and unrolled it as I fed it, and let it fall off the back edge after it was cut.

Around outlets we pried each stone or glass piece off the backing (which makes a mess of the backing) and cut it separately, and then set the cut pieces into the mortar individually. My wife is good for the finicky work like that. Obviously each stone needs to be marked and you need to keep track of where they go back.

In a few cases where there was a long piece blocking the outlet box screw, I pried the piece off the backing and notched it with a series of short saw cuts. Easy.
