I'm using this mosaic tile as a backsplash in our bathroom.


enter image description here

The gold spacers are a thin metal on top of another substance. The first three appeared to have some kind of ceramic under the gold facade and cut just fine with the wet saw. But two of the sheets have some kind of black rubber underneath instead, and the wet saw simply won't cut it. It cuts a bit on the edges, but once it's fully in there it simply won't push any further.

enter image description here

I'm hoping I'm just missing some pro technique here. The only option I could come up with was to cut each tile on the wet saw, then cut the rubber/gold on a table saw. That does NOT sound like a recipe for achieving a straight cut, but it's all I've got. Suggestions?

  • Do you have a tile saw where the blade is on the bottom and you have to push the tile through the blade?

  • Oh, thats interesting. Its a table saw style, but it has a moving deck so you don't have to slide the tile over the deck. That's a good design for a lot of use cases.

First, I have never cut this type of tile before, so this is just an unproven idea.

As you know, a tile saw doesn't have any teeth. Its just an abrasive wheel, so it will only cut through hard materials. The rubber on your tile, which is cooled by the water of the saw, just isn't what the blade is made for. The only thing the blade can really do is melt/grind through it.

What I would do is mark the cut line with masking tape on the front and back and then use a razor knife to cut a 1/4" channel in the rubber for the blade to run through. Then turn the tile over and cut.

Actually, just trying to cut the tile upside down might work and allow the blade to push the rubber up and out of the way, but the accuracy of the cut on the small gold pieces might suffer. I'd probably stick to cutting a channel out of the rubber when working with $20 tiles.

I bet an overhead style tile saw would just power through it, but I get that those are big and expensive and not worth it for smaller DIY jobs.

    I was thinking of post-cutting the rubber, but now that I look at the pic more closely, I agree, pre-cutting is the way to go. If not cutting an actual channel at least get a sharp blade in there to cut the rubber, hopefully allowing the tile-saw blade to push it out of the way to get to the ceramic. If there is a 5" section that needs to be cut off, make a couple of practice runs at 1" increments, just to hone the technique without destroying expensive tile sheets.
