20130927_122153  Back-rolling/brushing is a process of rolling or brushing after you spray the paint onto the substrate. It should be an “absolute” must when painting houses with “Wood” substrates. However, Is it necessary for “Aluminum or Vinyl” siding?

Spray painting applies the paint to the surface allowing the paint to dry and trap millions of microscopic air pockets underneath. As paint ages the resin oils that bond the paint pigments together begin to weaken. When exposed to high temperatures the trapped air pockets begin to expand, and causes a premature failure of the entire paint job, in the form of “bubbles“, “cracks“, “peeling“, and “chipping“.

Back rolling and brushing Increases adhesion forcing the paint into the grain, and pushing the air bubbles out, that would otherwise be trapped in the texture. This method will add at least 3 years to any paint job.

While some painting companies claim that spraying achieves the same superior cosmetic appearance, back-rolling/brushing  coats will “always” have superior durability because the paint has been worked into the substrate instead of simply laying on the surface.

WE USE spray machines to deliver the paint from the bucket to the substrate, but then use rollers and brushes to spread the paint and work it into the grain. The sprayer simply is the fastest way to deliver paint to any substrate, but the best workmanship always goes beyond that stage. One must spread the paint and work it into the grain in order to achieve the best “adhesion“, “durability” and “uniformity” for a superior end result.

With regard to a “uniform” appearance, if one just sprays the paint on the substrate, you will see the “overlapping” sprayed areas. When one uses a roller or brush to spread the paint, the overlapping sprayer marks will no longer be present.

Don’t be impressed with how fast a contractor can paint your home. Speed only lends itself to cutting corners, and inferior work. Quality work is worth the time it takes to complete it. Remember, you’ll be looking at it for the next 5-plus years.
