I have a question. I have a building that I will stuco. And before that I will wrap it, with tyvek. I read some where. When putting in windows cut the house wrap where the top of the window goes in or in this case underneath the house wrap. And then install the window. Is this a correct method. Thanks Hat

There's a constant source of clean water for you to use, and all you have to do is collect it.

Tyvek has a product that is made for stucco. It has channels that help get the moisture to drain. concrete (stucco) is not water tight and allows some moisture to penetrant it.
So I have been told.
Sounds good. I think I will use it. But still, do I wrap first or put the windows in first. And then wrap. Or like I said wrap with the stucco wrap. And cut an opening over the window and slip the window in the cut. Thanks Hat
Use tarpaper and keep all the laps facing downhill. That means tucking top of window in.

personally I'm not a huge fan of Tyvek. I believe a house can be "too tight" locking in poisons from the plywood,carpet etc etc. I'd go with 30 lb felt paper or even 15 would do but I over do things. Wrap it around all the windows and doors.

Well actually I'm building a shop. And as I said, I have to stucco (got to match the house). So that is why I will probably go with the tyvek. I'm a dyi'er so I'm trying to make this as easy as I can. But ant suggestion are greatly accepted. Thanks Hat
So what makes Tyvek better than tarpaper for stucco?.

I think he meant the tyvek made for stucco. . . which, if I can remember, has a drainage mesh or something built into it.
I know he meant that and didn't read the link about it. That would tell me everything the Corporation wants me to know about it. Whatecver goes behind stucco has to stop water. Regular ty won't. tarpaper will. and it is so much cheaper for a gauranteed good job that it's hard to imagine getting sold on something else.
Not trying to challenge, looking for illumination..

Now I'm lost :-)
Why won't tyvek stop water?? I mean, your reasons for not liking it, I'm curious! I'm partial to it because I'm a chemist, but really, I have no problem with tarpaper.
I do like it. ( I bet you're really confused now!)
But it won't stop water. It is made to stop wind and control drafts. If rain blows against it, 99.5% will run off. But it is far more permeable than tarpaper. Now you put a permeable surface - stucco - over a permeable membrane - tyvek - and you can expect moisture to wick through to the sheathing. Enough of it on a regular basis without adequate drying and you've got rot. Maybe OK in desert climate but not most places.
Also, stucco, to be strong, needs to cure properly. Moisture wicking out of it before it cures will weaken it. That is why, on the outside surface, sprinkling mists or wet burlap is used to modify the cure. tarpaper holds the moisture to the back side..

I love tar paper....Geezzzzz when I lived down south they tar papered the house and that was the siding. Lasted forever. Had something to be desired to look at but it seemed to work. I hate Tyvek....bet its cancer causing in some way. Just a gut feeling

LOL @ tyvek causing cancer!
Actually, I'd bet tarpaper had a greater association with increased cancer risk. Tyvek is inert stuff, and big molecules at that. The polyaromatics in most tarpaper are more likely to cause cancer.
OK guys I'm really confused. All I want to know is. What is the best thing to put on before stucco? And Do I sit my windows in before or after I wrap. You guys are are going to make me stop drinking,and start going to church. Hat
Like Piffin said tarpaper and think like a raindrop.

I didn't say Tyvek caused cancer. I said that I "thought " Tyvek is so tight a wrap that the interior of the poisons in ones home such as formaldehydes in carpets and plywood among a host of others might be so much more trapped in.

In my neck of the woods there have been problems with stucco and moisture. All stucco is now required by code to have two layers of 15# tar paper underlayment. Most use Grade D paper which comes in a double layer roll and is more water vapor permeable than regular tar paper.
It would be a huge mistake to use no underlayment. Like all unsealed cement products stucco will retain moisture. You need a good barrier underneath the stucco.
