What happens here

Once all primed areas are identified and prepped, apply the house's final body color paint over them. This technique is referred to as 'back-brushing.' Start by using a paint roller to apply an initial coat of the body color paint to the broader primed sections. Immediately after, use a quality paint brush to work the paint into the surface, ensuring complete coverage and integration with the texture. Pay particular attention to detailed areas, such as grooves, edges, and 'underneath these lips' or any sections where the material might be slightly swollen due to past moisture damage. The brushing action ensures the paint is fully worked into the surface and effectively seals the primer layer. This step is performed 'prior to spraying' the entire surface and is crucial for creating a robust, uniform, and moisture-resistant base, which will enhance the final appearance and durability of the spray-painted finish by preventing the primer from showing through and providing an even substrate for the spray application.

Goal: Apply the house's main body color paint directly over all identified primed sections using a roller for general coverage and a brush for detailed work, thoroughly sealing these areas before the overall spray painting process begins.

What they say

Hide

the dryer vent and anywhere where I've primed actually go back over prior to spraying and I back brush it with the body color of the house so I'm just going over all this primer underneath these lips that you know we're kind of swollen on back brush and underneath these and this is going to help seal all this back up and stop any moisture damage from this dryer vent
