    Default James Hardie Mitered corners

    I keep seeing photos in the James Hardie Literature that show lap siding with no corner boards.
    How are they doing this?
    - mitre and caulk?
    - alternate lap and taper the butt joint, caulk and paint the end?

    Both seem like tough joints for stuff that we cut 1/8 short and run into a corner board.

    here's a link to the one I saw this morning

    Paul, I have some photos of this done in my area.
    New it looks good, don't know how it will look in 10 years.

    We usually don't get much rain. My concern is the end grain gets saturated with water.

    Obviously the field-cut beveled corners need to be sealed.
    I will post a pic when I get back to my office.

    I've done it before, it's a pain especially if the house is out of square etc.

    I like right out the gate but like Bill said I don't know what it would look like 10 yrs down the road. Not to mention it's a layered product and cracks fairly easy, I'd hate to have on a outside corner around a a high traffic area.

    I put a compound miter on mine when I've done it but I've seen guy's just but it and put a single miter on it so the end is exposed.

    Around here they are using tin corners, I was on a complaint on this one and took pictures of the Hardie, but not the corners since there were no complaints on them, I tried to crop it down to focus on the tin corners but they are hard to see. This is one of our $800,000 tract houses, the stucco ones leak and the Hardie ones are buckled.

    Mark:

    What you see is what they were complaining about, I told them that it wasn't all that bad for Hardie, the problem is our DF studs and Hardie isn't rigid enough to straighten the wall out. Remember Chippy told us that Hardie had a better product in Australia which was thicker and the corners could be mitered? It was called Linea Board, I know they originally targeted vinyl at the low end but now that their product has reached such a high level of acceptance I wonder why they don't export their high end product? They even have what they call "soakers" to back and waterproof the corners when they miter them.

    Yes I do remember, that was an awesome looking product.
    They do need it here and I could sell it like crazy.

    He called me the a couple of weeks ago and we talked for 50 min.
    Cost him $2.20
    wouldn't that be nice to have overseas rates like that.

    There are lots of countries you can call for 4 cents a min.

    Mark,

    Have you consulted Telebright.com to compare long distance carriers? If
    not, go to Rate Plan Comparisons on their home page. I can get 5 cents a
    minute to Australia from where I am. Not that I've ever called there, or will ever have a reason to.

    I'm not sure if that technique would go over well here in Vermont. It looks a lot like the old asbestos siding when done like that.

    It's definitely a personal preference.

    Here in MN, we don't do a lot of mitered corners. A lot of aluminum corners, or XLD cornerboards.

    I believe that in years past, Hardie actually would not warranty mitered corners, but there is nothing in their Best Practices about it anymore.

    In case you hadn't heard, Hardie's new Artisan product looks almost exactly like the Linea pictures you have, but at 5/8" thick. All of the standard Hardiplank install rules apply, too. We're waiting for it to come to the Midwest now.

    The Artisan is only offered as a test in the south; it will be good when it gets to us here in the north.
    I noticed in the instructions they are back to 1 to 2" clearance instead of the 2" that is required now. Always something to appease the masses even if it isn't "best practice"
