Proper Moisture Management in Stucco Systems

Today we would like to talk about moisture management in stucco systems and why it is important. Stucco, after all, is not applied in one go. Rather, stucco application is in layers as part of system.

Understanding Stucco

Stucco is not waterproof. It is water resistant. Moisture management is important because it is possible for water to get underneath the outer stucco layer through cracks, visible or not, so the system layers underneath the outer stucco layers must be designed to allow water to channel down with gravity and away from the stucco system and building.

Stucco Systems

This is why stucco application is typically referred to as a stucco system. Not only are there several coats of stucco, but there will be an internal air space with vents at the bottom to allow water to drain away. Stucco systems are designed to manage water which will likely enter sooner or later. However, professional stucco application handles this water without damaging the building’s internal structure or entry into the building.

While it is possible for water to get behind stucco, stucco systems are prepared for that eventuality which is why stucco systems are superior to other cladding methods which do not prepare for the entry of water. A stucco system is a sophisticated building envelope that will keep your building interior dry.
