how to install vapor barrier???
I will be installing a 6mil poly vapor barrier on my kitchen wall after I put in the insulation. I assume this is best installed by stapling into the 2X4s? How close should the staples be? For a good seal, should the stapled points be caulked as well?
I see that it is recommended to use something called acoustical sealant to seal the poly seams. Never heard of this. Is this and sheathing tape at big box stores? Can someone explain how the sealant is supposed to be used in order to seal at the outlet boxes?
