People who have old aluminum sidings know that what the paint chalking problem is. This means that when you are pressing your hand or gently rubbing it on the wall the paint is all over your hand. Getting your paint to stick to the wall can be a big problem. This problem happens because of the paint oxidation process. The paint manufacturers think of this problem as a benefit because they say the paint is washing itself off.
The old vinyl siding is another problem. The UV light makes the vinyl side in time.
Many people are trying to deal with this issue in their house and they are constantly trying to find ways to get the paint to stick on the walls.
In order to make this work, you need a strong pressure washer that has about 3000 psi. With this washer you have to remove the old paint away from the aluminum siding. This will also remove some dirt too. You will have to start with the top of the siding and then work your way down. Maintain the pressure want close to the surface of the siding and just blow away all the old paint. Be extra careful when getting near corners, doorways, windows and soffits. You do not want to force too much power on that area and cause problems. You can also put some TSP or cleaning solutions to clean the algae or other stuff that got build up. After this whole process you need to let your home dry out. It is best if you do this in a week when there is a lot of sun so that the surfaces get dried properly.
If you try to repair the vinyl siding, you could use a surface de-glosser. This solvent product will easily remove the shine on the surfaces and will prepare the place for a good paint job. You can get this solvent form your local store. If you’re still not sure what to do, you might want to consult a professional like F&B Painting Contracting.
You can buy yourself an airless sprayer. This way, the paint will stick on the wall and it will be much easier for you. You can rent one or buy it. If you use a professional paint, which is much thicker, then you will need a more powerful sprayer.
This is a very important step and a big part of the result will depend on this. I like to use a good latex paint additive called emulsa-bond. I use this for the first coat. This bonding agent helps the first coat to stick better. I also recommend buying a very good exterior latex paint and not the oil and solvent paints. The latex paints keep up with the siding’s expansion and contraction. Besides, it will not require any primmer. I put the emulsa into the first coat. If you do use a primer, then you will have to add the emulsa into it before putting it on.
Then you will apply the finish coat and all will be done. These are the best painting steps.
