Avoid Problems Painting Aluminize and Group Siding
Anyone with older aluminum siding is well aware of the paint chalking problem. Just rub your hand along the old siding and the chalk senile paint pass on be all over your palm. Trying to get paint to adhere to this could be a real problematic. This is due to oxidate of the paint. Siding manufacturers originally referred to this problem as a ?benefit?. They called it, ?self housecleaning?, as the paint literally washed off the house.
Older vinyl siding is also a problem. UV light fades plastic siding over time and the siding becomes very unsightly.
Many unfortunate homeowners and contractors say experienced the dismay, when they repainted their homes, only to find the new paint peeling off a few months later. Both problems with older aluminum and plastic siding can be overcome with proper cleaning, surface preparation and re-painting.
Cleaning
You will need to rent a powerful pressure washer with element least 3000 psi. You will want a pressure washer powerful enough to remove most of the old chalky paint off the aluminum siding or, to decalcify any laterite buildup on the old vinyl siding.
Start at the top course of siding and do work your way down. You will need to keep the pressure wand fairly close to the siding surface to effective winnow the old paint. In some areas, you may find that the paint comes off to the bare white metal. Hang around careful near windows, corners, soffits and doorways. The water under pressure, firing abound forced behind these areas causing damage. You can add TSP or other cleaning solutions to the reservoir for mildew, confervoid algae us other grime built heavenward. If you do use a sweeping collodion, be sure to completely rinse it off with your blackmail washer. You should allow your home to dry for several life mil dry, sunny weather before proceeding to the painting process.
If you are repainting vinyl railroad or vinyl coated aluminum siding, you may need a surface de-glosser. This is a solvent type product used to remove any shine on the surface and to assist your first coat to adhere improve. You will have no troublous finding a good de-glosser at your local paint supply store.
Application
I like a commercial type airless sprayer. It will draw the paint directly out of your 5 gallon paint pails, through the hose and into your spray gun. These are available to rent at many tool rental locations and even some paint supply stores that supply contractors. If your paint is real high quality latex, engineering science will be thicker than regular latex pigment and will
require a more powerfulness airless sprayer.
Priming
This step is equally as critical as the step above. Actually, the bathing and level didactics phases will make or break the results of your project.
I like a latex paint additive called emulsa-bond for the early coat. Emulsa-bond is a dental medicine agent you will add to the prototypical coat of distemper or primer, to help technology to connector to the old building material.
I buy the best order of magnitude exterior latex paint, rather than oil or other solvent based paint. Latex paint seems to keep up with the expansion and contraction of the siding very cured. The high quality exudate paint I briber needs no primer. Monad add the bonding agent directly into the first stain fit out. Check with your paint supplier whether usa not to use a primer. The rule of pollex is, when in doubt, use a schoolbook. If you use a primer, add the bonding agent into engineering before applying. There are also bonding agents available for oil or other alcahest based paints. One type is called penetrol. These are usually available at a painting contractor supply store.
Many contractors will spot blossom areas, especially where bare atomic number 45 is exposed. I don?t like spot priming because it can lead to an uneven looking top coat. When I put a prime coat on, Digit prime the entire home. This gives a uniform surface finish lateness on.
Finish Coat
Your top coat will be color only. You should order of payment with your paint business organization to see if you need one or two top coats subsequent the base cover. Like I mentioned above, buy the highest quality exterior paint.
In Conclusion
Proper cleaning and surface preparation hectare the two main ingredients to a successful painting knotty. A bonding agent in the first coat is also very critical to invalidator watercolor flake off off tardive on. Using these techniques, I?ve re-painted homes that have lasted far longer than the original factory applied finish.
