Anybody with older aluminum siding can be nicely aware of the paint chalking drawback. Just rub your hand throughout the outdated siding and then the chalky mature paint will in all probability be throughout your hand. Trying to get paint to stay to this could possibly be a real downside. That is because of oxidation within the paint. Siding manufacturers originally referred to this drawback as being a "benefit". They known as it, "self cleansing", as a result of the paint actually washes off the house.
Older vinyl siding is also a problem. UV gentle fades vinyl siding over time and the siding becomes very unpleasant. Many unfortunate homeowners and contractors have experienced this dismay after they repainted their homes, solely to find the new paint falling off several months down the road. Each problems with older aluminum and vinyl siding is perhaps overcome with correct cleansing, floor preparation and re-portray.
You will have to lease a robust stress washer with at least 3000 psi. You will want a stress washer highly effective sufficient to remove most of the previous chalky paint off the aluminum siding and, to take away any grime construct up. Begin on the high course of siding and work your means downward. You'll have to hold the strain wand pretty near the siding surface to successfully take off the outdated paint. In some areas, you could find the paint comes away to the naked steel. Watch out near windows, corners, soffits and doorways. The water under strain, might be pressured behind these areas creating loads of damage.

I like to make use of a industrial sort airless sprayer. It can draw the paint immediately out of your 5 gallon paint pails, by way of the hose and into your spray gun. They are available to rent at many software rental locations as well as some paint supply shops that provide contractors.
This step is equally as crucial because the step above. Really, the cleaning and floor preparation phases will make or break the outcomes of the job. I want a latex paint additive known as emulsa-bond for the very first coat. Emulsa-bond is a bonding agent that you simply add to the first coat of paint or primer to assist it to bond with the old siding. Buy the very best grade exterior latex paint you could afford, as a substitute of oil or different solvent based mostly paint. Latex paint appears to carry up with expansion and contraction on the siding very properly. The high-quality latex paint I purchase wants no primer. I add the bonding agent straight into the initial coloration coat. Verify with the paint supplier whether or not to make use of a primer. The rule of thumb is, when unsure, use a primer. Should you use a primer, add the bonding agent into it earlier than placing on. There's also bonding agents accessible for oil or different solvent primarily based paints. One kind is named penetrol. These are usually out there at a portray contractor supply store. The place bare steel is exposed. I detest spot priming as a result of it usually leads to an uneven wanting high coat. Once I put a primer coat on, I prime the whole space. This offers an excellent surface finish in a while.
Your high coat must be color solely. You must check with the paint producer to see in case you need one or two top coats after the base coat. Like I discussed above, purchase the perfect quality exterior paint you could afford.
