What's in the Can?

Proportions vary, but the basic ingredients that go into most exterior paints remain the same.

Solvents
Quick-to-evaporate liquids keep binders and pigments in suspension.
Pigments
Powdered minerals and man-made colors give paint its hue and opacity.
Additives
They control dry time, leveling, and mildew, among other things.
Binders
These resins coalesce to form the paint film after the solvents evaporate.
