Should I Use Latex or Oil-Base for Painting the Exterior of my House?
Here is a question that you get a lot. Should I paint the outside of my house with latex or oil-base paint?
Many people believe that oil-base is more durable and longer-lasting. But the contrary is true. Oil-base paints dry brittle and don't allow your walls to breath. Moisture from the inside of your house tries to escape out of the walls and can't penetrate the oil-base.
The result is cracking and peeling. Also, as oil-base paint ages as it gets brittle leaving aligatoring type cracks. Also oi-base paints fade more in direct sunlight.
Latex paints on the other hand, stay flexible and hold their color longer. Latex paint also can breath and lets moisture out of the walls. Also, latex exterior paint is predominent in todays paint industry.
You will find a lot more latex exterior paint on the market than oil-based paints with the exception of high-gloss enamels that are sometimes used for front doors entries and their side-panel and window areas.
The only exception is when it comes to exterior primers. Some painters believe that an oil-based or alkyd primer is more durable under a latex finish.
I had a lady ask me what I would use on old brick. I said I would use a alkyd primer and top-coat it with a latex paint.
When it comes to aluminum siding I would wash it first and then seal up any remaining chaulkiness with a latex primer and top-coat with latex paint. I would tint the primer to the finish coat color.
On vinyl siding you can use two coats of a quality latex paint. I recommend washing the siding first to remove any dirt. Also, it is always good to read the manufacturers instruction on the paint can. They know their product best.
And never paint a dark color on light colored siding. The sun will warp the light colored plastic if you use a dark colored paint. It isn't designed for dark colors. It is best to stay with off-whites or the original siding color when repainting light colored vinyl siding.
I mostly use latex primers. I spot bare wood with a alkyd or oil-based primer to stop bleed-through and after it dries I top coat it with a coat of latex primer and finish with the main coat of latex paint.
