Walls

[rac]

Am at the point putting up chipboard on the outside walls on garage.Question is which side to weather is better?I've heard about smooth side and ruff side and looked at other build pics and there's has blue and red lines on it.Mine doesn't.It has this side down.Which is the best way ? Thanks.

Either way if it is going to be covered. What you DO NOT want to do is put the smooth side up on a roof. On sidewalls it does not matter

Going to be about 4 to 6 mo. before covered.

If you are not going to put sideing over it right away put the smooth side out and give it a good thick coat of house paint.
You need to waterproof it somehow.
It is not ment to be exposed.

Smooth side in....the rough side with the 'lines' on it show you where your studs are 'supposed' to be...makes nailing a lot easier....

As for smooth or rough side out and resistance to water....does not really make a difference.

At a min I would put at least one layer of tar paper over it...if you want to save yourself some work...use the stuff that is designed for stucco or the Tevek (or what ever it's called). Either one will survive the winter.

What is stuff that is designed for stucco ?

I will have to agree that both sides will absorb the rain equaly well.

I was just thinking the smooth side would be easier to paint.

yeah, gotta cover that man..otherwise it's just going to **** up water like a sponge

Use Tyvex or equivalent, the totally **** felt paper (tar paper, 15 or 30 lb) you get from the major chains expands after nailing/stapling, even after unrolling/exposing to the sun for hours, felt paper of years past did not, new stuff causes misery.

No it won't. There was a rather lengthy thread on this early in the year. If left out laying in water or if left exposed for years it will deteriorate, but if only exposed for as long as he is going to have it exposed it will not go bad. Granted, I would cover it if possible, but it is nothing to lose sleep over if it isn't. Houses go up everyday and houses are exposed to the weather without any covering over the OSB for months at a time if in a rainy season.
