Hardie board/shingle

[Michael Bulatovich]

Anyone seen these products after the factory paint has failed?

[Edgar]

Have not personally. We just specced this stuff recently on a school modernization.

They grow mold which can be powerwashed off. Haven't noticed a lot of color change from sunlight, however.

Is that like Hardie har har board? :)

Seriously, though, I thought it was called Hardiboard or Hardiplank. Am I wrong?

[Edgar]

It's definitely Hardi.

The finish looks pretty tough, and they guarantee it for 15 years, but I was wonder what it might look like *after* it fails...Flaking? Peeling? (Worst cases.)Powdering? (Not so bad.) Fading? (What doesn't change color?)

I haven't seen any failures myself, but the product has been around longer stateside than it has here.

[Michael Bulatovich]

Yeah, but made by Hardie.

[Michael Bulatovich]

TAP! TAP! TAP! Is this thing on?

The products are named like that. The company's is a family name, I think. They also make a shingle that's very nice for traditional work (locally ~$9.50/sq.ft.), and a big 'panel'.

The question was, **how** does the finish eventually fail?

Same as anything else - through lack of maintenance. Water gets under the finish and starts blowing off the paint due to vapor pressure. The Hardie line of siding products take and hold paint beautifully. The paint job will last far longer than if on wood. The big caveat is that the stuff absorbs water and all cut ends must be sealed with paint. If you take care during the installation you can expect to get about double the life of a paint job. The stuff is easy to install. There are shears that are great for cutting the fiber cement stuff without raising god awful amounts of dust.

Thanks for that, but in asking "How does it fail?" what I meant was, "What is the mode of finish failure?" I.E., flaking or peeling or powdering or just fading? IOW, what will it look like when it has failed? Is the color beneath the paint a Portland grey?

[Jude Alexander]

Yeah, isn't the manufacturer named James Hardie or something like that?

[Jude Alexander]

lol

Yeah, I understood that. Just having my fun. I had a hard day.

[Edgar]

I was thinking the paint for certain colors was integrated.

I was not aware that "Hardie" products came pre-painted. I have used the 4'x8' sheets, stucco finish, with the trim pieces, but they came pre-primered not painted. After 8 years my project is looking fine. I have seen where the product has "rotted" if allowed to be covered with moist organic material. The board becomes crumbly, but the finished suface retains paint and general look.

[RicodJour]

Unless you use something other than latex paint, it'll peel. Solid body stain doesn't peel - it wears/leaches away. The fiber cement is regulation cement color.

I wonder how the plant takes to English ivy...

[Michael Bulatovich]

[Michael Bulatovich]

Thanks. That's what I suspected. Not the best mode of failure....

[Michael Bulatovich]

Planks and panels come in 6 light 'standard' colors and 14 others, mostly deeper and quite nice, if a bit 'safe'. Trim and soffits come in 7.

Ouch. By 'covered' do you mean buried at grade, or leave-muck at gutters?

[RicodJour]

? As opposed to what? Rotting wood? Let me list all of the maintenance free sidings:

Hmmm, short list. Maybe siding products with no drawback will do better:

I guess not.

What exactly are you hoping for?
