Restucco? Why would I need to recoat or restucco my Home? Over time, rain erodes the thin coating of stucco that contains the sand that creates the texture layer. When this happens, the texture can easily be removed if the wall is cleaned with a pressure washer, or with time as airborne pollutants and rain continue to erode the surface of the stucco. To prevent the loss of your texture, the stucco should be recoated or fresh color coat (restucco) every 20-25 years.
