Enamel, available in a wide variety of colors that are ready to mix, may be used on any kind of surface but is especially suitable for highly trafficked areas that require a hard, nonporous finish, such as doors and trim.

House paint is more versatile than enamel but also more problematic. Its VOC content makes it a better candidate for exterior painting, though several states have banned it because of air-quality regulations. In states where it is available, it generally only comes in quart cans, meaning it is an expensive choice for siding.

Alkyd paint is vastly preferred over latex paint for surfaces that are glossy or to which latex has trouble adhering. In addition, alkyds dry at a slower rate than latex, allowing brush and roller marks time to smooth out. However, this also means that if the paint is applied too thickly, it will sag.
