Keeping Water Out: Common Stucco Moisture Issues
What to look for:
-A peeling layer of paint on the interior of the building or a dark or discolored spot on the exterior
-A lack of sealant around doors and windows especially around areas not covered from the elements
Flashing Issues
-Flashing is meant to direct water away from the building
-Missing flashing at the intersection of roof or chimney with hard coat stucco or EIFS often causes most damage
Insulation Issues
-The hard coat stucco system must be 2 inches above soft grade and EIFS must be 3 inches above to ensure prevention of wicking and repulsion of termites
-Foam insulation must be properly wrapped and adhered to provide fully protection of the exterior system
-All EIFS must utilize fiber reinforcement to stop any issues with elemental imperviousness
