The reason as you may have read is that when there is a vapour barrier in homes in hot humid climates that rely on air conditioning for human comfort that vapour barrier is effectively on the wrong side in the cooling season. Materials have a moisture vapor transmission rate that is established by standard test methods. Available at distributors nationwide.

If the perm rating of the paint is not indicated on the label find the paint formula. It is common to use plastic sheeting as a basement vapor barrier but waterproof paint will work just as well. The paint formula usually indicates the percent of pigment. Moisture vapor barrier primer finish interior latex is a coating designed to reduce the loss of moisture through walls and ceilings.
