Your Questions About Stucco Are Answered Here!

Stucco is a beautiful and unique way to customize and update your home. The question of if stucco can be applied over a painted brick wall is one of the msot common we encounter at Custom Exteriors. Plaster is a cost-effective finish, relatively easily installed, that improves the appearance and creates a water-resistant wall surface. A painted surface will not typically absorb water and, as such, is a substrate to which stucco will not readily bond—at least not uniformly. There are two basic alternatives to covering a painted brick surface with a new coating of portland cement plaster. 1. Sand blast or water blast to remove the paint in its entirety, then direct-apply a two coat system. It is essential to have a surface that is uniformly absorptive to accept the plaster coating. In addition, it may be beneficial to use a bonding agent or dash-bond coat with this approach. 2. Attach paper-backed lath or install appropriate building paper between wall and attached metal lath to provide a moisture barrier and to serve as a bond breaker. Apply traditional three-coat stucco to metal lath and accessories. In this approach, the idea is to treat the plaster like a sheathed system, using metal lath to support the plaster on the substrate, while completely isolating the plaster layer from the backup with building paper. This prevents a partial bonding situation, which could set up undesirable stresses in the plaster and lead to cracking. For more answers about stucco, click here.
