   你可以滚动或喷洒它。我会聘请一家经验丰富的涂抹器，因为他们通常知道施加正确的湿厚度，良好的覆盖率并正确跟踪安装过程。无论你是否浪费你的钱都会有所不同。联系涂抹器推荐的制造商或零售商。

   Armando;
   谢谢你提供的详情。There are not experienced applicators in my area that I can find, so I will have to rely on the manufacturer's advice. Thanks again. Russell

   Mind the movement of the building.

   "...Back to movement. Joints and inside and outside corners open up and close up all the time. The gaps get bigger and the gaps get smaller. Let me repeat the point here…they don’t just open up…they go back and forth. The water control layer we cover them with…the liquid applied membranes that are spray applied, brush applied, trowel applied, or whatever, need to be elastic. Think rubber band. There is elongation and recovery. There is cycling. There is fatigue. There is aging.

   还有更多。总有。关节和角落事项的几何形状。关节和角落处理的材料特性以及关节和角质的几何形状。

   With a “difficult” joint and corner the material properties of the liquid applied membrane are a big deal. With an “easy” joint and corner the liquid applied membrane is stressed less. Not too many liquid applied membranes have the material properties to handle “difficult” joints. But with the field experience over the past two decades with liquid applied membranes we can turn “difficult” joints in to “easier” joints. The best combination of course is combining a high performance liquid applied membrane over a joint that has been made less stressful...."

   John;
   Thanks for the advice and link. My house is very straight forward and except for a bump out that serves as a mud room, and where the wall meets the roof overhang, it is a 32' 6" square. I presume that the stress points to which you are referring are the corners of the house and the windows and doors. I will read your suggested link and see what I can learn.
   罗素再次感谢

   2. Read the link. Good reading and a lot of good information. My house is a level two but I will not be using closed cell polyurethane as exterior insulation., so

   Question 1: the sealant needed at OSB joints and corners? Silicone, ?

   问题2：如何达到液体WRB膜和绝缘板之间的1/32“间隙？或者只是确保保温板可以采用一些水分？

   罗素再次感谢

   I know they are used a fair bit, but I'm still not too comfortable with liquid applied WRBs.

   您依靠WRB连续性的密封胶和磁带，加上窗口细节始终是反向圈。

   打电话给我老式，但我更喜欢我的手机作为依靠引流重力的衬垫。据我所知，重力从未失败过。

   In this case I'm struggling to see how a fluid applied WRB improves your assembly. Air sealing is much easier with a quality tape.

   阿科斯;
   谢谢你提供的详情。以下是我认为液体WRB的优点：紧固件周围的密封（用于捆扎）;不需要WRB本身的紧固件，这意味着没有渗透;窗户和门的连续覆盖;无需磁带。
   我在过去的30年里，我在啜饮的外面使用了Tyvek，并且在剥离了一些壁板和一些Tyvek之后，我对Tyvek所表演的方式并不满意。
   It has been suggested by Martin H. that the WRB on SIPS should be a bumpy housewrap in order to facilitate drying. Do you have any suggestions along these lines?
   在我开始工作之前，再次谢谢我，希望在五月开始。

   拉塞尔，

   墙壁不是屋顶。他们不需要是液体紧的，钉子孔并不重要：

   https://www.buildingscience.com/documents/insights/bsi-067-stuck-on-you

   甚至有一个专门的网站，我的谷歌foo目前失败了我，所以我找不到它。

   The bottom line, any properly installed WRB will work.

   The most likely reason you were not happy with your house wrap over the SIP is that there was no capillary break. It would have been pretty much the same no matter if the wrap was sheet good or self adhered. Without a capillary break, the small amount of moisture that will make it through the siding gets trapped between the siding and the OSB thus what you saw.

   Martin's suggestion of bumpy house wrap is the minimum to help with this. Even better, install rain screen strapping to add in a proper capillary break. Besides helping with keeping the sheathing dry, a capillary break will also significantly increase the life of any painted siding. Since it is a simple addition, it is well worth the small amount of extra work.
