One surprising point , we found it wasn’t the local deluges that ruined the underfloor canvas , but the everlasting Morning dew that wet the canvas
every day … Keeping canvas moistened continuously , softening TB2 used to attach it and allowing the water to eventually soak into the floor (OSB) …. and attracting Ants …
The simple Drip edges made of drywall corner edges only 1 1/4” deep works perfectly to keep the floor dry underneath …
Once again here’s the drawing ..using the drywall corners ( Thanks to Steve ,George, and Tac for the info)

Easy, inexpensive , and it WORKS !!!
Wow!
Thanks GPW...
Yes...being the 'world traveler' that I am...

....it might get lost on some that I am from the same neck of the woods as GPW....well familiar with the oppressive heat, humidity, and constant rain deluges of my beloved home turf...but, can't say I miss any of that stuff....I could use some good food...besides what is cooked in my RV....(hard to find here)....and I miss so much more....but....being wet from head to toe from walking the distance from the house door to the car door....not....and 20" afternoon showers....not....
We don't get much rain here in the total category....but....we have other challenges.....with not being able to find any 'flat' ground....think the movie Sgt York...rich people down in the somewhat flat bottom land....and us poor folk (less-wealth)....up on the ridges....plenty of trees, plenty of moss covered rocks, plenty of areas within a few feet of anything that might not get direct sunlight at all, or very little due to angle of hills intercepting the sun.....it gets more of a problem this time of year as the fall's Sun low angle doesn't hit the sides of hills much.....so this time of year with the increased frequency of cold fronts and the accompaning rain showers......its a mold factory.....
I haven't seen that image before this time? I don't know how that can be....actually I do....just the way it is.....
It really is a shame that there hasn't been a good summary of methods for foamies put in a 'pinned' post in quite a while.....there are probably a handful working on books or websites on a pay to play premise (nothing wrong with that).....except I need good info right now.....I am cognitively challenged? I know.....hard to believe....

.....but true.....

.....certified
I am past terminal.....expired actually.....time sensitive....is very dear to me.....
While perusing through this website is a privilege.....and one that I am extremely grateful for.....(and I am no stranger here....although....I am new as a contributor { that could be debated for a few seconds}......).....
It is a very frustrating experience for someone on a mission.....I don't have years to complete my project.....I don't have years to redo my efforts a few times....and I don't have the money....
So....I know a bunch of you guys try real hard to help ( and I do know the difference between 'help' and 'holding hands'...and even 'doing it for you'...)
Might I suggest.....that it is time to revisit the pinned posts for 'foamies'..........most of what is pinned isn't really helpful in the way it is 'pinned'....and its dated....and superseded......it looks like it was very helpful when it was 'pinned' but most of it was done years ago.....
Really just trying to be helpful....from this end....someone searching...
Okay, back to your response.....thanks for that image.....I bought a handful of drywall corners to try in different tests....even a bullnose....and I have a stapler (not a red one)....
So, Drip Edge....on the build list....
Now....what you mentioned in your post about TBII softening......I caught that in I believe '1' post after reading maybe ten thousand posts going back and forth between TBII and Glidden Gripper as the way to apply canvas to foam.....then I was caught off guard when I read your report of your floor being destroyed.....by water....and your thought that the TBII has dissolved and allows the canvas to rot.....I was ready to toss the TBII....(almost.....I was in the process of second sourcing that....or at least trying to....and that is a frustrating experience without asking.....there is just so much content on here....)
This is probably me....the frustration I am experiencing.....I was expecting like I read from others....I was expecting to be able to wade through enough pages to find the information I was looking for.....by I am convinced now.....I won't get there....that way....the only chance I have to start actually asking questions....
So, that is probably what I will start doing....and finish the FoamStream thread.....
