Application Method: Applying the top coat can be done via (a) the brush and roll method (b) airless spray or (c) a combination of both methods. The paint application method we employ is highly situational and depends on a number of factors. Spraying allows for a faster application but requires that a lot of time be spent masking off areas to prevent over spray. The brush and roll method is ideal when masking off an area would require more time than just painting an area by hand.
