Fiber Cement Siding (HardiPlank) Cutting Tips?


ive done many hardiplank siding jobs, and ive tried many different cutting methods.

Since Im here I figured I would see what other professionals opinions are for the best way to cut it. And what techniques and tips they can offer to make the best cuts.

Score and snap? Electric shears? jigsaw with carbide coated blade? circular saw with hardi blade?

Weve used a chop saw with an old blade before and just swap out for another old throw away when it gets bad, but it creates a ridiculous ammoount of dust. but its fast and leaves a good cut.

never been able to get the shears to leave a clean cut, maybe a technique you found that will help me?

havent tried the jigsaw blade or an actual hardi blade for circular saw.

Any suggestions are much appreciated, id like some advice before spending money on a new tool or expensive blade for next siding job.

We have used the Dewalt fiber cement blades. Still a good bit of dust, but the blade lasts a long time. We previously tried some cheaper fiber cement blades, but they never last. Not sure if they still make the Dewalt ones, but I think they were about $50 or $60.

For notches, we just use a regular jig saw blade, and change it when it gets dull.

Where is Tom? He would say a track saw and dust collector. After a blade change it can then cut your ham sandwhich

The Hardi saw blades work pretty good I have found.

We use the bullet tools cutter and a shear for dust free cutting. I have found that the shears cut better from the back side. If you are going to use a saw, the hardi blades are worth the price.

We usually use a big Guillotine and a angle grinder with a diamond blade.

Irwin Hardi blades in chop and table saw hooked to vac.

Electric sheers on the staging to get up the gables.

Carbide blades in multi tool & jigsaw.

I have the siding snap cutter but its too slow and tough to get square cuts. It also snaps the end of the cut so the siding has to be cut face up with the bottom toward you.

Here we go! Why not ask what is the best oil to run in your truck is...or for that matter what’s the best truck? (you’re going to get a billion answers and this has been rehashed half a billion times.)

Let me give you some practical advice. Go get a fiber cement blade, put it on regular circular saw and try that. If you’ve been using regular blades all this time you’re gonna be in heaven. Whatever you do don’t spend $500 on Malco tools for one job until you try the Hardi blade.

They really do last a very long time. The last one that I bought survived 23 square of hardy siding plus I’ve still got it in the truck having done a dozen or so chimneys and Gables. I like the red one from HD. (Now I’m gonna get screamed at for referencing the big orange store)

Re: Fiber Cement Siding (HardiPlank) Cutting Tips?


I already have a fiber blade for my SCMS with dust collection and my Festool track saw. I am covered. No way would I rip fiber board of any kind without dust collection.

What is wrong with asking for an opinion on which siding to use? Or which engine oil for that matter. If it has been asked a billion times, how about offering a link to a informational thread? I have worked with Hardi and it seems okay to me, but...I also respect other peoples opinions, and one of the great things about this forum is that most of us can learn from others.

So the LP Smartside website says it's lighter and stronger, both of which sound good, is easier to work with, also good, but having trouble comparing how fire resistant it is compared to fiber cement siding. This is a huge deal out here, I'm guessing it's more like regular wood in that respect but not sure.

P.S. Also says the LP is more impact resistant.

I'm a fan of SmartSide. I do think they need to do a texture/smooth trim.

"Fire resistance. LP SmartSide siding qualifies for use in California’s high fire hazard zones, as specified by the strict California building code."

Re: Fiber Cement Siding (HardiPlank) Cutting Tips?


The smart side is way easier on the crew to install. Lighter, cuts better, not dusty. Not 100% sure but you wouldn’t think the firerating would be as good. Definitely better impact resistant, so if you were using a rain screen and worried about people hitting it smart side would be better. In my climate the smart side seems to move less.

All that being said we usually use the cement board as it is still a good product but half the cost where we are located. The thing that bothers me the most is that the various cement board companies seem to have inconsistent mixes or the change their formula from time to time some times for the good, some times not. Does anyone use canexel anymore? Used to use that a lot but not much anymore. I hear people talk about caulking between the joints of the cement board and smart side. Is that a common method?

I back flash at the seams, prime and paint the ends, no caulking.

The warranty seems a little sketchy on the smartside. It's a 5/50 with full replacement for the 5 then prorated after that. 5 years isn't very long construction wise......

Re: Fiber Cement Siding (HardiPlank) Cutting Tips?


I use a cmt fiber cement blade on my 20v dewalt miter saw. Throw another same size blade in my tablesaw. I don’t bother buying a 10”. Just the small size runs in either for that thickness of material. Makes a massive difference in dust if you haven’t tried it before
