Exterior Painting Tips: Back-Brushing
As the painting industry has evolved, airless sprayers have become more and more prominent for exterior painting. The benefits of using an airless sprayer include the ability to paint larger areas in less time, and the uniform appearance created by the sprayer’s even application. These factors make it the perfect choice when painting a large house. However, there are also some negative aspects to using an airless sprayer. Besides the extended period of time spent on prep and cleanup, paint applied with a sprayer can sometimes just “sit” on top of a surface rather than really fill in the ridges, nail holes, and cracks, which creates the best possible adhesion (this is particularly true of rougher painting surfaces). Although spraying creates a beautiful, even appearance, and can be applied in a thicker coating than the traditional brush-and-roll application, the sealing and adhesion isn’t always satisfactory on rougher substrates. This cannot be overlooked, because proper adhesion to a surface is vital to a quality, long-lasting paint job.
What is back-brushing?
As you have likely assumed, the solution to the dilemma described above is back brushing (or rolling)! By back brushing after spraying, we are essentially getting the best of both applications. Back brushing is the process of working the paint into a rougher surface after it has been sprayed. Back brushing should be done while the sprayed paint is still wet. With a brush or roller, work the paint into the cracks and crevices on the surface. This helps create a better bond to the surface, as you are now able to work the paint in to the smaller imperfections on the substrate.
When should you back-brush?
Back-brushing is an important step in an exterior paint job for rougher surfaces. Examples of such substrates include cedar siding, T1-11 siding, and just about any type of surface that has become cracked and weathered over time and being exposed to the elements. That said, new, pre-sealed surfaces need not be back-brushed; the best example of this type of surface is the popular hardy plank siding.
