Stucco guy 35 yrs in az, went from no moisture barrier to single paper to 2 ply paper to tyvek to stuccobwrap and drainage wrap rubber wrapping around all openings and penetrations , out of the business a couple years now but this new Keene product looks pretty neat and if done properly and inspected should work, I was upset everytime there was a change every few years but looking back I think it all helped ., except for taping all seams I not sure about that with 6 to 12 inches of overlapping if that is necessary for 20 dollar a roll tape, but anyhow I enjoyed watching your presentation even tho I'm done with my stucco and veneer license
In the 35 years you were in the industry, a whole lot has changed with regard to WRBs and how we assemble the these different assemblies. I hope you were able to pass some of your knowledge along to the younger generation before you left the trades. To comment on taping seams of WRB's, your right that the overlap along is sufficient for keeping water out of the wall, the main reason we tape seems now is to deal with air leakage, as most WRBs function as both an air and water barrier if detailed correctly! Thanks for your kind comment!
I live in Maryland and am planning to build a custom home with zip sheathing, rainscreen, and fiber cement cladding. Are you saying with the new codes in addition to the zip sheathing an additional WRB such as Tyvek would be required? Thanks.
Where are you seeing in the code that two layers of Tyvek is a code compliant system? Reading section 2510.6 it says that some kind of space is needed between the WRB and stucco. Is a layer of Tyvek considered a "nonwater absorbing layer"?
That is correct, Tyvek is considered a "non water absorbing layer", and since Tyvek also has a drainage efficiency of 90% or greater, it would be considered a compliant assembly! Great question!
@@noonanbuilds Would that not be the same with a layer of Tyvek and a layer of Type 2/60 minute paper? Or is the 60 minute paper not considered to be a "non water absorbing layer"?
Putting more layers over the wall is madness when the application of the stucco is usually done wrong, scratch,brown coat and finished, not finished in One or two hits same day,that's why walls fail and crack +mixing the mud wrong !
Great video! Why not do a full trip around the house with tyvek home wrap and then a trip around with tyvek drainvent? I’ll be using stone and hardie lap. Also, do you know the difference between drainvent and drainwrap?

Learned a lot. Most of our work is in the marine zone.
I'm glad to hear that. Wish you the best on your building efforts.
