Anyone here have experience with paint/primer that has vapor barrier properties?

Latex paint would seem to offer a 'plastic' vapor resistant barrier that eliminates the need for stapling 2 ml thick sheets of plastic sheeting all over a construction.

I've found a handful of paint manufacturers that produce such paint, but no local professional paint stores that provide it.

I've been told that such things DON'T exist, as well as being told that "you're delusional". The latter sort of rubbed me the wrong way as I have a psych Dx (anxiety related) to start with.

Problem, you need a certain low level of permeability intaglio Sep 2013 #1

Yes. Generally, vapor barrier this requires a permiability rather less than 1.0 HereSince1628 Sep 2013 #3

If not then the low level of water vapour inside from cooking, heating and breath can build up rotting timber and drywall.

Look at building membrane such as Tyvek or equivalents

The lower the number the better.

The primer/paints that I've looked at yield permiabilaties of .6 and less.

That's very similar to 2 ml of plastic. The advantage is clearly labor savings that is eliminated by notdealing with sheets of plastic.

Anyone use such a thing?
