Following cleaning and repair, the application of a bonding agent ensures the new stucco firmly adheres to the existing layer. This adhesive primer is brushed or rolled onto the surface, creating a receptive base that significantly enhances the new stucco’s adhesion. By establishing a strong chemical and physical bond, the bonding agent mitigates the risk of delamination, securing a durable and cohesive finish between old and new stucco layers.

This phase involves skillfully applying the fresh stucco mixture, a carefully prepared blend of cement, sand, and lime, ensuring uniform coverage and thickness across the wall’s exterior.
