For hundreds of years, people have been using oil based paints for their impermeability and toughness. Unlike water, oil does not dry by evaporation. It dries through a process of oxidation that converts the oil into a polymer chain. There are, however, several disadvantages to oil based paint. The paint pigment in oil paint is suspended in the solvent.
Applying a new coat of paint over an older one is common to do when house painting in Danville , especially when you want to update the look of your house. For instance: it's time for a new look for your home, and one of the renovation projects is to repaint. You're ready to do it, but you're stopped by just one problem: you're not sure if the old paint is latex paint or oil-based paint. Do not worry, because this article will guide you through in determining whether the old paint is latex or water-based or oil-based before you need to apply a new paint. The general rule of thumb here is that an oil-based paint can be painted over latex, but a latex paint can't be painted over an oil-based paint. If you try to paint latex over oil, the latex paint won't adhere properly.
Determining, definitively, whether a given paint was oil or latex has always been a bit of a problem, but an important one as you can paint oil over latex, but not latex over oil unless you use a special 'super adherent primer' first. I used to recommend taking a bit of paint thinner on a clean contrasting colour cloth and wiping hard. If any colour comes off, it is oil based paint. If nothing happens, it is latex.
