Which produces the better, longer lasting paint job on aluminum siding, spraying or brushing?
The key thing to consider when repainting aluminum siding is not the method of application, but the surface prep. Aluminum siding is normally painted only after it has faded and chalked. If the chalkiness is not removed, the paint will not adhere properly. Spraying will be much quicker than brushing, and as long as the proper tip size and pressure are used, it will produce excellent results. Duration, Resilience, or SuperPaint Exterior Acrylic, applied to a properly prepared surface will produce a quality long lasting finish.
