Stucco is a finishing plaster that can be applied to the outside of brick, concrete or block walls in order to add new life to a home or to hide any inconsistencies or irregularities in the home's existing exterior finish. Stucco can be applied by most homeowners of any skill level with the assistance of the right tools and the stucco mixture. Before the stucco can be applied to an exterior surface, the concrete, brick or blocks must be properly prepared.
Inspect the exterior brick, concrete or blocks. They should be clean and free of any dust. If the exterior is not clean, remove any dirt, debris and dust with a power washer.
Allow the exterior walls to dry before continuing.
Apply a layer of concrete bonding agent to the exterior walls with a paintbrush. You may need a ladder or scaffolding to apply the bonding agent depending upon the height of the home or structure.
Allow the bonding agent to dry completely, which could take several hours depending on the outside temperature.
Apply the stucco.
