How do I repair and prevent the cracks that keep occurring from the ends of wood facia boards?
The cracking that you are experiencing on your fascia boards is caused by moisture entering the substrate. The moisture causes the wood to expand and contract as it enters and leaves the wood. This action stresses the wood and the results are the unsightly cracks at the ends of the board. To remedy this problem, remove all the loose and peeling paint on and around the affected area. This can be accomplished with a scraper or wire brush. Once the paint is removed sand the exposed wood to fresh wood. Fill the cracks with caulk. Allow the caulk to dry thoroughly (follow the label directions for dry time) prime the bare wood with an enamel base primer such as Bristols General Purpose Enamel Primer and allow to dry. Topcoat with two coats of Bristol Weather shield or Timber coat premium acrylic.
