How to Easily Cut Hardiebacker Cement Board DIY

[mrdavidmitchell]

For detailed cuts, like pipe slots, toilet circle, etc. is to just use a big pair of pliers and nibble away at it. No dust, no chance of breaking the board, and perfect fine detail. Nibble straight lines along the edge or work your way out from the center. Full control, no hazardous dust flying everywhere. Silica will cause lung disease. PPE minimum for silica is N95, not your standard dust mask.

Makita and Pac Tools make power shears for fiber cement, no dust at all. Way better method than a saw

I was wondering about the table saw method. Thanks for covering it. Good vid!

2:50 Had me worried...You sure looked determined to cut that electrical cord. LOL!

Also a great video of how to improperly use a grinding tool.

Should we get the hardibacker wet before we install it like in your video? :)

Hardie Backer web site says to score then pull board UP to snap off, NOT Down like drywall.

[baitmaster]

Always have the power tool cord coming from behind you, not fighting to keep it out of the way.

You actually snapped the board on the opposite side the manufacturer recommends. Their video advises you to lift the board in the direction of the cut side versus folding it away from the cut side as in your video. I guess it worked anyway though...

i've used them all and ended up going with a Bosch fast cut wood jigsaw blade and switching out every 15'. Much less dust and fast.

A few were saying you were not safe with the table saw. What are they talking about? You showed all the cutting methods except the carbide razor blade. I will try and cut that way tomorrow.

1:30. Why does the James Hardie directions for scoring and breaking this board say to snap it UP (towards the score) not away?

[swm-smcu]

A grinder with a diamond blade works best for me. It's faster and easier to score it with a diamond blade also.

Manufacturer says don't use high speed power tools. The dust is killer.

dude: you happen to have a ping pong table in the background. This is fortuitous. I want to build a outdoor pingpong with cement board. I have never heard of cement board until 10 minutes ago when I was searching for build outdoor pp table. I came across 3x5 cement board.

Actually was looking at my tile saw and thought hmm, and that's why I'm here. Going to give it a try.
I've been using a table saw for over 40 years. Only use a push stick when there is less than inch and half between blade and fence.
Sometimes it's easier to use a tool you already have than go out and buy a tool you are only going to use for one project.
If you are planning to use a skill saw or table saw wear a mask and plan on discarding the blade, maybe more than once depending on how much cutting you are going to do.

I really thought you were going to get that grinder cable

I already purchased Hardiebackers, and I installed self leveler on my OSB. Can I install Hardiebacker over the self leveler with thinset and screws??

Do not do the hammer method with 1/2” . You will risk damage to your board and it would be a shame if you had to purchase another board and make extra unnecessary joints due to breaking and having to use extra pieces. The board is made of fibers and and cement and corners will break off easily. Cut it outside or use a shop vac and mask for clean cuts. I prefer denshield for walls. it’s drywall that’s waterproofed on one side and cuts easily

Use a push stick on the table saw, to get that small piece clear of the blade. I've seen the blade catch it, and come out at 100mph, catching you right in the gonads.
