How much do oil-based stains affect vapor permability?
I stained my siding recently (bevel siding) with oil based stain.
Since my house is built fairly vapor open, I am curious how much oil stains will affect the vapor permability of the building’s envelope and ability to breath?
I am guessing it leaves the wood still semi vapor permeable because almost every house has paint/stain.
How do you guys approach this when building a vapor open house? Even if it makes it vapor closed, I do have 1/2″ furring strips behind my siding, so would that be suffecient to allow vapor to escape from the house?
