Oil-based paints contain either natural oils, like linseed oil, or a synthetic alkyd, They consist of a pigment and a resin in a solvent thinner. When the thinner evaporates, the resin forms a hard coating. Painters should use an oil-based paint for any surface where they want the finish to last for a long time, and they are not planning to change the color often.
Oil-based paints are extremely durable and can withstand routine contact, making them ideal for moldings and trims. And because the resin of an oil-based paint creates a hard coating that isn’t breathable, this option resists stains and rust over time. Keep in mind, though, that oil-based paints have a stronger odor than water-based paints, and will take more time to dry. They’re also harder to clean, too.
Water-based paints, which are also called latex paints, consist of a pigment and binder with water used as a carrier, Joey continues. They are the most common and environmentally responsible paint option. They provide great color retention over time, dry faster than alternatives, and produce fewer odors. And lastly, water-based paints can typically be used over existing oil-based paints—the reverse isn’t true.
Since water-based paints hold their color longer than alternatives, it recommends them for exterior walls that are exposed to the elements and interior walls that experience a lot of moisture, such as kitchens, bathrooms, laundry rooms, and mudrooms. Water-based paints come in a range of finishes, too, and can be cleaned with soap and water.
