Unfinished spruce clapboards over rainscreen system
Hi, looking for thoughts and opinions on using unfinished spruce clapboards over a rain screen system. Durability? Weathering? Mildew?
Will sealing with a waterproofer extend the life of siding or is air gap enough to do that?
Furthermore, does anyone have experience with Vermont Natural Coatings penetrating waterproofer with juniper on exterior siding?
Thanks a lot.
