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.

[@emghee2510]

Awesome tip! I was wondering about cuts for toilet rings. Thanks!

[@mrgrey361]

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

[@DIYeasycrafts]

Great tip!

[@1divemaster1]

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

[@marilynjackson5752]

Thanks, I like the tile saw idea!

[@CenterTree777]

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

[@shinysquirrelclub]

Yep. I noticed that too.

[@drumhailer547]

To sell more materials from fuck ups

[@origionalcatastrophe]

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

[@nblackmore]

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

[@paulmaxwell8851]

I saw that. It seems like a dumb idea to me. I'll try both, but I'm pretty sure the way you see it done here is more sensible.

[@neilfitch]

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

[@drumhailer547]

Absolutely cement always adheres to wet materials far better

[@prestonghim748]

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

[@CenterTree777]

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

[@jarekkam81]

I really thought you were going to get that grinder cable

[@CHEECHMUN]

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.

[@timothymaffei82]

Thank you for showing the options.

[@DIYeasycrafts]

My pleasure!

[@zozoart]

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.

[@aaronkraemer9887]

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...

[@19baitmaster51]

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

[@RedBeardCarpentryWoodworks]

Great tips!!

[@shinysquirrelclub]

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

[@drumhailer547]

Respirators are your friend

Thanks Woody!

[@timothycarr8565]

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.

[@JHelak]

What blade are you using with the jigsaw?

[@xsolidxprezx]

J Helak they sell carbide blades for jigsaw.

[@19baitmaster51]

@@xsolidxprezx Amazon also has masonry cutting blades for jig saws.

[@19baitmaster51]

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.

[@swm-sm6cu]

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

[@rc4me288]

Thanks for video great help

Cutting a silica based board like Hardiebacker with a saw produces dangerous silica dust (the main culprit in Black Lung.) Here's a warning from the James Hardie company: • NEVER use high-speed power tools (e.g.saws,grinders,etc.) to cut JamesHardie® products indoors as they may generate excessive silica dust. • NEVER dry sweep-Use wet suppression methods or HEPA vacuum for clean-up. • To further limit respirable silica exposures,wear a properly-fitted, NIOSH-approved dust mask or respirator (e.g. N-95) in accordance with applicable government regulations and manufacturer instructions.

[@karozans]

Silica is not dangerous. That's a leftist environazi myth.

[@lonnie008]

OK mom

[@paulmaxwell8851]

@@karozans Give your head a shake. Silica dust can be very dangerous if breathed day in, day out for years. We're talking about workplace exposures, not one-time exposure. It happened to a friend of mine, and the lung damage done is irreversible.

[@pokerchannel6991]

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.

[@pokerchannel6991]

fun fact: pp table is 5x9. cement boards can easily make a 5x9 type configuration..

[@PoisonJarl71501]

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

[@somewhat-32W3R]

nice swimming pool

[@GrandmasFolly]

Great vid, thanks!

[@Tattooclownfish71]

Is it waterproof that’s all I want to know brother lol

[@m151tacticaltruckpartsandr6]

I appreciate that you are trying to help people out but your video lacks basic power tool safety.

[@Michael-dx1uv]

Shut up, it’s not his job to make sure you don’t cut off your finger

[@MarioR23]

Now they sale a power tool called Backerboard shear made by PacTool.

[@niallchurch2679]

What about cutting circles??

[@tonycarlos2154]

Jigsaw, recip-saw, or a hole saw.

[@jcfpv3454]

That dust will kill you

[@garyofnyc]

You're throwing way too much silica dust out there. Just score and knock out. Don't saw.

[@murdokmcgrady8464]

Wow, how not to use a table saw. Never let go of the piece that is between the blade and fence

[@WYO_Cowboy_Joe]

I wouldn't follow the tips from this guy unless I was desiring to lose some fingers or even a hand. Holding work with one hand while holding the tool and trying to manipulate the cut while fighting with the cord in the way is one dangerous situation. Almost like playing with a live grenade. There is a reason someone invented HoldDowns, clamps and vises. Use 'em!!!

[@GM-wn7sb]

Hard to cut when scribedand leaves uneven break dust is dangerous wear mask! The longer the cut the hard when scribed also a short scribed cut is very hard to snap when it short 15 inches or less. Great product but easy cut is bs

[@boostbeast8731]

Do yourselves a favor and go buy a $20 fiber cement blade for your circular saw.

[@dovco8565]

No mute no watch 😮

As a club Table Tennis player, seeing that table in the rain gave me PTSD.

Lose the guard on your angle grinder. It's holding you back!

You were totally dangerous with that table saw cut.. Learn how to properly use a table saw or your gonna regret it.

Just use a skillsaw bud much faster and safer

[@Bigbrunibelow]

It’s absolutely terrifying watching you improperly cut with a grinder.... waiting for the video to turn into how to almost chop limbs off

[@utila94]

On a high note, he did leave the guard on the grinder.

[@apflor323]

Awesome instructional video on how not to use power tools😆

[@masonjar9023]

Metal and masonry saw blades are solid discs. There are no teeth. It’s like hitting yourself with a power sander. Not gonna instantly remove limbs like a wood saw.

[@catfirst2593]

That's anything but "easy".

Wood blades to cut masonry? Really? There is more bad information in this video than responsible good information.

[@ARDENHANNA]

Grinder skills are terrible

[@cboatify]

This is a truly foolish video . The use of the table saw is frightening -no push stick .And what's with the grinder ?
