Yes. Rhino Shield can fill in smaller hairline cracks, but for more significant damage, we offer stucco & wall repairs to fix it before the application of our Rhino Shield products. If there is enough rotting or failing wood that we cannot sufficiently patch or repair, we will provide you a quote for wood replacement as part of the estimate process so that we can guarantee that your property is in proper condition to ensure the success of our Rhino Shield coating system.
