What is the best way to cut cement board and do you need to pre drill it before screwing it down?
This is Mike, The Home Depot Answer Man ;
While you have two great replies already, I would just like to add that we now have at The Home Depot a new blade by Diablo designed specifically for hardibaker and cement board. Called the Hardieblade .
It's a 7 1/4" blade and will fit a regular circular saw. Diablo states it will outlast 60 conventional carbide blades!
I hope your project is coming along well!
It looks like you've already got some great advice. So I just wanted to add to it by giving you a How to link. If you're like me a few pictures are worth a thousand words. I hope it helps out. Let us know if you have any other question with your tile project or any other project. If you get a chance post some pictures to show us what a great job you did. Thanks
I've had to cut this stuff on more than one occasion and there are a couple ways to do it. The easy way I found is with a masonry blade in your circular saw. What is that, you don't have a circular saw? No problem, just score the board where you want to break it and snap. I would use a razor knife to score it so you can cut the fiber reinforcement. You can only break this in straight lines, otherwise you will need a reciprocating saw with a masonry blade.
As far as screwing the board down, you do not need to pre-drill it. I would recommend using masonry screws or Hardibacker screws. I hope your project is a success and let us see your pictures when the project is complete.
