I was looking into “encapsulating” my crawlspace by some manner or other. From what I can tell the way to do this involves (primary) some thick poly (.15 or more) along the the soil and up the walls. The poly is then sealed to the walls.
Currently my crawlspace is vented.
Whilst I was doing my research I stumbled upon a vapor barrier paint. Would this paint be a suitable substitute for a poly barrier? Or should I not even worry about that and just use a poly barrier?
–Update
My crawlspace floor is dirt and is almost entirely below grade.
