    Default OSB lap siding......

    The homeowner replaced deteriorated portions of exterior surface with pieces of OSB. I don't know if this is a suitable material. Any thoughts?

    OSB needs to be protected from the weather and elements.

    Okay!

    Here's another answer: That's what they make T-1-11 plywood siding for ... to be left exposed and *protected* by just staining or painting.

    The paint isn't enough. Just like "Masonite" 1 paint chip or scratch and it will swell and wash out the glue making very nice termite food or mulch on the ground.

    Not to worry John, at least I didn't think you were serious.

    Thats just there to cover up the large cracks in the foundation.

    I agree with John, it just needs a good coat of paint.

    My biggest question is, What is behind that OSB? As John above implied, I have to wonder why someone is covering up the foundation?

    From the picture, I get thats its a room that has been added onto a patio. It doesn't appear to be an actual foundation wall.

    OSB is not designed for exterior finish. But I have seen billy bob use it.
    They do make OSB siding panels though, it has a skin finish like masonite.

    i can take you to a house in the historical district of Washington, N.C. with OSB on one side. Now I'm not saying what the neighbors think . . . But it actually can survive quite a while if you soak it in motor oil.

    My brother in-law had a barn that he would soak all the wood with used motor oil. He moon-shined for awhile and it caught fire. I hear it could be seen for quite some distance away.

    Mike,

    I remember it was the talk of the town for a bit.

    I worked on a ranch in Okeechobee Fl for a while where wood fence maintenance consisted of 5g buckets of hydraulic oil & a roller, might not be able to get by with that these days though.
