TL;DR
Spray back-brush is the painting technique of working sprayed coating into the surface with a brush or roller immediately behind the spray gun, while the film is still wet. The spray meters material quickly and evenly, while the brushing drives it into wood grain, gaps, and texture and breaks the surface tension that causes thin bridging over rough spots.
What it means
Spray back-brush is the painting technique of working sprayed coating into the surface with a brush or roller immediately behind the spray gun, while the film is still wet. The spray meters material quickly and evenly, while the brushing drives it into wood grain, gaps, and texture and breaks the surface tension that causes thin bridging over rough spots. On bare cedar siding, fences, and stained decks, many coating manufacturers require it for warranty coverage because adhesion roughly doubles versus spray alone.
