Is brushing or spraying the best for exterior aluminum siding?
On One Hand: Spraying Paint Is Quicker and Looks SmootherAfter proper prep work, spray painting exterior aluminum siding is the easiest way to make it look like it did when it was installed. It takes less time and usually covers well with one coat. The biggest downside is the possibility of over spray because the wind can carry the paint a long way.On the Other: Painting With a Brush May Be BetterOne of the hardest obstacles for novice spray painters to overcome is overlap, in which two painted sections overlap each other, which causes the paint to be thicker in that area. Until you can master it, brushing the paint on is wiser. Brush the paint with horizontal strokes to at least keep them parallel to the siding.Bottom LineSpray painting the exterior of a house is the best way to go if you are a professional painter.
