Drywall Paint, Oil-based
We’ve discussed the properties of interior latex paint, now we will take a closer look at oil-based enamels.
Oil-based paint is similar to latex-based paints in that it contains color pigments, binders, carriers and additives. Where it differs, and where it obtains its strong odor, is in the VOCs. Volatile organic compounds or VOCs are the portion of the binder that evaporates when the paint dries. Latex-based paints contain water-based VOCs; whereas, oil-based paints contain a high amount of mineral spirits and petro chemicals. These chemicals include synthetic resins, polyurethanes, and silicones. There are more natural alternatives that include linseed oil, soybean oil, safflower, tung, and cottonseed oils.
Oil-based paint does not breathe whereas latex paints will. The tight seal formed with oil-based products can cause the paint to crack and peel as the moisture tries to escape. Because latex-based paints are 50%-90% water, they have less of an impact on the environment than the more chemical filled oil paints. Additionally, oil-based products are messy to apply and clean, and take much longer than latex to dry.
When applying oil-based paint, be sure all of your surfaces are carefully masked and protected. Have paint thinner nearby for quickly cleaning any unwanted spills. Oil-based paint is best applied with a roller or a brush, and should be allowed to dry a couple of days between coats. Choose from a wide range of color choices and sheens. Be sure to work in a well-ventilated area, and to wear a respirator as much as possible.
Despite the long list of negative qualities, some consumers prefer oil-based products because of their durable nature. They can look just as attractive as latex-products and the color options are the same.
