Cutting cultured marble...
 
Hi guys, I am cutting the backsplash off of a cultured marble vanity that is 69" long. I don't have the time or manpower to take everything apart, so I would like to cut it while it is installed. I have seen posts regarding cutting cultured marble, however they are generally not installed. I bought a multitool, and asked what type of blade should be used, but since the big box store guy had never come across this he really didn't know. So I used the wood blade, and it quickly became clear that it wasn't gonna work. So any suggestions? Any help would be appreciated. I am not concerned with appearance as I am going to tile where it was, and will be replacing the top as soon as I am able to. Thanks!!!

And what will happen to the radius?

I personally think you are are wasting your time. The way to cut those things is to remove them and turn them upside down. Then they can be cut with a circular saw and a masonry abrasive blade. The multi-tool wouldn't be the tool to use and I know of no blade for a multi-tool that would cut the product. Those things are made of stone you know.:)

I would think of anything you can do to not have to cut it.

I have used every multi tool out there. Every blade, every cutter, and I can not think of something that would do this with a clean line that you'd be happy with.

The cut will be hidden by the application of tile and that's reasonable. The problem is...without clear access to make a clean straight cut the cut itself will not be reasonable. That product can also chip under enough stress.:)

Ok, so what if I scored it and chipped it away with some other tool? Like I said, I don't have the manpower to take it out. I do mean this literally, and not cutting it is not an option at this point.

Not gonna score it not gonna uniformly chip it. That stuff is made of marble dust in a matrix with a gelcoat top exterior.:no:

That may be but it is only going to weigh about sixty pounds (or less) I think.:yes:

Okay...let's see what someone else has to say, I'm out of ideas.:)

I don't think you are going to be able to get a good cut in place very easily. You would have to take the faucet out anyway. Best thing would be to get some help and take the top out. How big is the top? I have put in some double sink tops that were 8' long. They were extremely heavy for two people.
