You can paint aluminum siding. You will first need to clean it with a power washer, let it dry, and apply a good quality latex primer. Then you can paint it with a water-based latex paint. See the details in the link below.Ive been told i cant paint aluminun siding, true or false?
I wouldn't recommend it. The advantage to aluminum siding is that it doesn't need to be painted--if you paint it, you'll have too keep on painting fairly regularly, because the paint will peel off, just like any other. If you're really desperate for a new look, I'd recommend fresh siding. You might consider vinyl siding, too--it dents less, which is a big benefit when you're in an area with occasional hailstorms, like we are.
I don't know who told you that. You can paint it.

Many latex primers are not suitable for use with weathered aluminum siding.





Sunshine, rain, and pollution erode all paints. The paint film develops tiny cracks and pinholes. These permit water and air to penetrate the actual siding. Aluminum isn't harmed by water, but air does cause problems. The air oxidizes the aluminum.





Just about every latex paint, including primer, contains ammonia. When ammonia comes into contact with oxidized aluminum it creates a gas. This gas can cause small bubbles to form beneath the paint film. This creates poor adhesion which in turn leads to premature paint failure.





A better alternative is to prime the weathered aluminum siding with a thinned down oil based metal priming paint. Leading manufacturers recommend using one pint of paint thinner to one gallon of high quality oil based primer. This primer creates a barrier between the oxidized aluminum and the finish paint. However, before you even think of mixing up and applying this primer, you need to prepare the surface for paint. If you read the labels on most paints, they will instruct you to apply the product to a clean, dry surface. How do you get yourself clean? Soap, I thought so!








Using any high quality powdered soap product, a heavy sponge, and a scrub brush, wash and rinse down your aluminum siding. You will notice that some of the old paint will wash off in this process. Don't be alarmed. Rinse the siding until no additional paint pigment can be detected in the rinse water. Avoid the use of a power washer for this job. Power washers, when used by a rookie, can direct water behind the aluminum siding. This may cause a leak into your home.





Allow the siding to dry for several days. Apply the thinned metal primer. Consider having the primer tinted to one half strength the color of your finish paint. Your finish coat should consist of a 100 percent acrylic latex exterior house paint. Buy the most expensive paint you can find. It usually contains the highest volume of acrylic paint resin. A higher volume of resin translates into a longer lasting paint job.





You should apply the finish coat of paint within 48 hours of applying the primer. Absolutely do not paint in direct sunlight or on windy days. These conditions reduce the dwell time of the paint. The finish paint needs to dry slowly to achieve the best mechanical and chemical bond. Cool, overcast days are the best for painting aluminum siding.

Using a top quality acrylic latex house paint can make aluminum siding look new again -- for a fraction of the price of residing. A new color scheme can also be chosen, and with proper surface preparation and application, the job can last 10 years or longer.





A top quality, all-acrylic latex house paint will provide the best performance on this substrate. This type of paint exhibits superior durability, and will resist fading and chalking for many years.





First, clean the surface by power washing or hand-washing with warm, soapy water, then rinse.





One thing to be aware of with aluminum siding is something called ';surface oxidation.'; This occurs when bare metal is exposed due to extreme erosion of the original factory-applied coating. If your siding shows this unsightly, white oxidation, remove it by carefully rubbing with steel wool. Rinse to remove any residue and spot-prime bare areas with a quality acrylic latex primer.





A top quality 100% acrylic latex exterior paint will provide good adhesion and excellent resistance to fading. It also forms a thick, uniform paint film that is aesthetically pleasing, and retains the look of the original surface -- smooth or textured. The paint can be applied by brush or, better yet, an airless sprayer.
Yes you can,with a good latex paint.If it is chalking you will have to do a very thorough job of cleaning the old siding.
You can but it will not last.
False. We painted our aluminum siding 4 years ago, and it looks great. The siding must be powerwashed. Then use a form of paint called Alkyd. Ours was from hallman paints. Our siding was yellow, and we painted it white. Just do it!
