A development nearby has several new houses that look like they have
been coated (sprayed?) with foundation waterproofing. Something new to
me; anyone here had experience with it it? Looks to be real labor
saver over applying Tyvek or similar.
There are some sheathing sheets that come with a built-on barrier, and
then the seams between boards are taped. It makes for a very quick,
complete and durable drying-in process. Perhaps that is what you're
looking at. I'd think anything sprayed that would stick would create
big problems with overspray and environmental concerns.
Two guys can wrap a house in a few hours. You think that someone
could spray a house in a few hours? There are some potential benefits
for sure, but I don't know that faster, easier or cheaper are among
Interesting concept, though. Stuff like that, and the coated
sheathing I mentioned, require a drying-to-the-interior approach to
moisture in the walls, otherwise it's rot and mold city USA.
One of the local roofing suppliers told me of a roof coating product
they have nicknamed "Batman Suit" because of how tough the stuff is.
It's a lot like that indestructible spray on bed liner. The salesman
told me to never get it on my skin because it will have to wear off.
I wrapped my house when I built it. The wrap goes up fast enough but
taping the seams takes a while as does the the window and door
openings. I've wondered how much air the staples holes let in. To me
it has always seemed counter productive to put up a barrier like Tyvek
then make a few thousand staple holes in it.
I'll bet that spray does a good job of sealing around windows and
doors. Maybe a combination of the two methods would be worthwhile.
Wrap the house with Tyvek then spray the seams, windows, doors and
any other openings in the walls.
