What happens here

For exterior painting, back-rolling is typically reserved for areas with existing damage. If exterior surfaces show signs of blistering, peeling, or other damage, they should first be sanded and primed. After priming, these specific areas are back-brushed and back-rolled *prior* to spraying the main paint coat. Once the main paint is sprayed, it is generally not back-rolled, as this can lead to touch-up issues and discoloration. Trim elements such as fascia, window, and door trim are usually hand-brushed and rolled, so back-rolling is not applicable to them. For the main body of an exterior house, back-rolling is not typically performed unless there's specific damaged areas that have been prepped.
