Chris, do I absolutely HAVE to back roll stucco? What about 2 coats of just spraying? My house in about 3000 sq ft and I’m doing it solo. Thanks! If the surface is in good conditon we do not. If it has blistering you need to back roll. Thanks for watching my videos. Please subscribe to my channel. Find me on Facebook https://www.facebook.com/IdahoPainters for more tips. Give me 5 stars please.
