Is there an easier way of cutting Wonder Board (cement board)?

Question

I used a razor but it killed the blade in about two seconds. Is there a special saw for this stuff that won't make a huge mess?

Answer 1

Here's everything you need to know about wonderboard. Mechanical cutting throws too much stuff in the air that is really bad for your eyes, lungs and skin.

It really doesn't matter how sharp the blade is. You're not actually cutting the board, you're scoring it. You can do that with a nail, if you had to. Don't bother pressing down too hard on the knife, it won't get you through the material any better. You just make three or four passes with medium pressure and snap it like sheetrock. As long as the blade hasn't gotten rounded at the tip, it will work just as good as a new one. Any type of saw is going to make a mess and isn't necessary.

Answer 4

There is no easy way to cut cement board.

It's just messy, I just bite the bullet and cut it with a masonary blade in a skill saw (I use my near death saws for that kind of work) that concrete dust is bad (were a mask). If your duing long rips, have a helper with a vaccum or compressor, suck or blow a clear line of site.

That suck or blow comment will raise eyebrows. just leave it alone.

Answer 5

Use a utility knife and score it just like you would drywall. Once scored, snap it to break it apart. Even though the blade gets dull it does not require much to snap the cement board.

Answer 6

No!! We use a diamond blade on a side grinder at work it throws dust and particles everywhere. Wear safety glasses or face shield, long sleeve shirt and gloves. A standard zip cut blade will also work but you may need several.

Answer 7

There's no method of power cutting I know of that isn't messy. But, a skillsaw blade mounted backward in the saw works really well for cutting.

Answer 8

Buy a 'score and snap' knife from the hardware store. They have a tungsten tip on them and you just run it along the mark where you want to cut a few times then snap the sheet.

Answer 9

Yes any saw with diamond blade, even a grinder with a diamond blade. Cuts like budder

Answer 10

If you score it both sides, will it snap over a sharp edge, or perhaps over a dowel on a flat surface?
