5 construction tips that defeat the drips
Minimize end-grain exposure.
Moisture moves through end grain like soda through a straw, so plug up end grain by sealing it with finish or caulk, or capturing it in a joint. For end grain that points to the stormy sky or touches the ground, consider covering it with a cross-grain cap, as shown. Also, keep the edges of laminations from facing up, and fill the edges of plywood with epoxy or primer and paint.
