A Step by Step Guide to Painting Aluminium Siding

One can repaint old aluminum rather than replaced. Here's the process

1) First check whether the siding is aluminum or galvanized steel. Galvanized steel should not be painted with any oil based paint; some paint manufacturers specify latex only over steel. Notice that the Galvanized steel will have a black siding. But remember that before painting the aluminium surface, it needs to be dry. If painting is done under wet conditions, the paint will not be consistent and it may have a chemical reaction and end up corroding the painting aluminium siding. In this way the painting and aluminium siding will last longer and you won't need much money in repairs.

2) Use any lime scale/mineral deposit/hard water stain remover to clean the aluminum by applying it .Thereafter agitate the surface with a brush or sponge and finally rinse it water.

3) If the surface is in poor condition such as peeling or chalking, you need to primer coat. Use a good oil based exterior primer. The use of an oil-based primer is preferred over a latex primer because the later generally contain ammonia, which reacts over time with aluminum to form microscopic gas bubbles, leading to premature failure of the primer (and hence, paint) surface.

4) Remember that a light sanding is helpful before applying the final finish coat on the painting and aluminium siding. Sand with a 150 grit sandpaper. You don't need to worry about using a sand paper if you are coating the painting aluminium siding with a latex paint

5) Add a finish coat of acrylic latex. Use a low luster or satin finish. It looks more like the factory finish. For a real smooth job, use an airless sprayer with a .017 gun tip. Always remember not to apply by exposing in direct sunlight which may lessen the amount of time for paint to be on surface. Let it dry after finishing
