EIFS over lap siding
i have a 2 story built in 1920. It has no moisture issues. I am having the exterior walls dense packed with cellulose. The exterior is horizontal lapped siding over 1×6 horizontal sheathing. After dense packing… can I apply EFIS using house wrap and 2″ foam board over the lapped siding? ..or must it be removed down to the sheathing?
