Exterior Acrylic Latex Paint: Basic Ingredients

The basic ingredients for exterior acrylic latex paint are almost as same as any other type of paints. The four basic ingredients are pigments, additives, resin, and solvent. A solvent is nothing but water when it comes to latex paint. And as the paint dries, the solvent eventually evaporates and disappears.

After the solvent evaporates only the resin, additives, and pigments stays as the ingredients. However, you can have different types of finishes on exterior paints. For example, there is a glossy finish if you like it shiny, and there is also a classy matte finish available too.

Though exterior paints have a solvent similar to interior paints, the percentage of pigments is higher in exterior paints. The pigments which fade faster are used in interior paints and not exterior paints.

A good quality exterior paint is able to withstand all types of weather conditions. It can withstand random temperature changes. It can protect the house from UV rays as well as prevent rainwater from licking inside.

As the weather changes the surface underneath the paint contracts and expands. So the resins used in exterior paints are really flexible. Also, exterior paints have additives that are helpful for stopping mildew, preventing fading, and also resisting tannin.
