On Cement-board Siding

This is the text of an email I sent a friend about my experience and thought on cement-board siding --

=====
Around here [north-central Ohio], there were two options: "Hardie Board" (James Hardie Co.) from Lowe's, and "Alura" from Menards.  I used the "Hardie Board" on the sunroom (2nd/3rd floor addition), but overall I used the "Alura" even though it was more expensive. 

[Edit: I bought the siding from Menard's even though, ever since they went full "face-diaper nazi" during the Plandemic, I do my best to not give them any business. The prices at Menard's are generally lower than at Lowe's and Home Depot, but I *never* go to Menard's unless I can't find what I want at Lowe's or Home Depot; that's how much they pissed me off harassing me about not wearing a face-diaper. On top of which, while they "officially" ban mere pets from the premises, the use the HIPAA laws as the excuse to ignore that particular policy.  Odd: you don't dare make an assumption -- nor query -- about the health-needs of that person who clearly has brought a mere pet, not a service animal, into the store, but you're fully qualified to determine that *my* health won't be injured by forcibly/artificially restricting my breathing with an utterly useless and pointless cloth.]

I'll try to list what I see as pros and cons.

At Lowe's, the cement-board siding was in stock (*), and I could buy pieces individually, as I wanted/needed them. That (*) is because there are two widths, and in the end they didn't have enough of the width I was using. Or, perhaps it's that they started stocking pre-finished, rather than the "raw" I'd been buying.

On the other hand, the "Alure" from Menards was special order; a full "pallet" being 256 pieces (or, 1536 sq.ft. coverage).

"Hardie Board" — As far as I can tell, it comes only as "textured" to look like aged cedar which had been allowed to weather for many years without a proper coat of paint.  I *hate* the fake "wood grain" they put in vinyl siding, and that hatred is the main, or even only, reason I went with the "Alure", despite it being at least $2.00 more per piece.  Though, as it turns out, once the "Hardie Board" is painted, I doesn't repulse me, as I thought it would.

Pros — cheaper per piece; higher cement content (which results in some 'cons', and what might be a very big 'pro' in the long-term); available as unfinished (which for me was a 'pro', though obviously, other people will prefer the pre-finished);

Cons -- higher cement content: thus, heavier per piece, and more brittle; also more dense, meaning you'd need to drill pilot-holes if you use screws as attachment (just with the 12-15 pieces used on this project, we dulled a cement bit while drilling the pilot holes).  If I recall correctly, they make special nails for this siding, but I much recommend using screws, as one slip of the hammer could ruin your day.

By the way, the reason I put off re-siding the house for so many years after it was clear that I need to do so is that I was fearful of the cement-board being *too* brittle. The vinyl that is on most people's houses was never an option, I despise it that much. I was hoping to find a third option, such as a *solid* (and smooth surfaced) vinyl.

"Alure" — Like the "Hardie Board", it comes "textured" to look like aged cedar, but they also make smooth, untextured.  It can be either pre-finished (Sherwin-Williams paint) or "primed" (I use scare-quotes, because I couldn't see any priming on what was delivered to me).

Pros — lighter, due to being made of more fibers and less cement than the H-B; being less dense, drilling pilot-holes wasn't absolutely necessary, as the "self-tapping" screws we used were able self-tap; being less dense, it was easier to cut the pieces, and it was possible the "trim" or "fine-tune" it with a utility knife.

Cons — more expensive per piece; buying less than a full "pallet" of 256 pieces adds a surcharge for "breaking" the "pallet" 

Potential Con -- it seems to be composed of compressed layers; the potential 'con' is that several times, perhaps because we made some pilot-holes too close to the edges, the layers of small areas at corners de-laminated. 

==============

As mentioned, I bought unfinished siding, and painted it myself.  As Providence arranged it, right after I ordered the siding, I happened to come across 20 gallons of paint formulated for decks and floors (including for cement) on clearance at Lowe's for $20 per gallon. I bought it all. It wasn't exactly the color I had in mind, but it was close, and I really like how it looks contrasted with the yellow of the trim.
