Being thicker, oil-based paints take longer to dry (sometimes days or weeks) than latex paints which dry within minutes, and only one coat can be applied at a time, whereas multiple coats of l…
Versatility
- Acrylic paints can be used along with other materials, such as pastel, charcoal, pen. They can also be diluted with water to create a watercolor-like effect. Oil paints are not as versatile.
Type of Finish
- Oil-based paints have a glossy finish whereas latex paints are available both in a glossy and matt finish. One disadvantage of a glossy finish is that imperfections are easily visible.
Durability
- Oil-based paint is more durable and stain resistant than latex paints. Once, cured latex paints last longer without cracking or peeling whereas oil-based paints may turn yellow or oxidize with age. This is the reason why oil-based paints are used for areas like kitchen, bathrooms, trims and other exteriors, whereas latex paints are used for interio...
Availability of Colors
- Certain colors like Prussian Blue and Zinc white are available only in oil-based paints, and not in latex paints, whereas fluorescent colors are available only in latex paints.
Odor
- Oil-based paint has a much stronger odor than latex paints. Thus, if you use oil-based paint make sure it is a well-ventilated area and allow the odour to diffuse before entering the room.
Toxicity
- Oil based paints are toxic and hazardous to health, while latex paints, being water-based are not toxic.
