We recommend the Spray and Back Roll method when painting the exterior of your home. The Spray and Back Roll method simply combines the two traditional methods, Spray and Hand; therefore, you’re getting the best of both worlds. This method entails one painter spraying a liberal amount of coating onto the substrate while the other comes behind him and rolls it out. As a result, you have the efficiency of the Spray method, while the Hand method provides you with the security that the coating was properly pushed into the surface creating a uniform appearance. The Spray and Back Roll method is highly recommended on porous substrates such as Stucco, EIFS, Concrete. The Spray and Back Roll method isn’t necessarily applicable to smooth or hard to roll surfaces like metal or lap siding.
