Oil-based and water-based paints are quite different from one another. While water-based paints are generally preferred, oil-based paints have their own advantages as well. In this article, we explain the differences between oil-based and water-based paints. We also discuss whether oil-based paint is better than water-based paint, the disadvantages of oil-based paint, and when you should use oil-based paint.
Oil Based or Water Based Paint?
Paints containing synthetic resins are called synthetic paints. Water-based paints, which are generally acrylic paints, dry quickly. Today, water-based paints are the most preferred wall paints. So, which is better: oil-based or water-based paint? Here are the most important differences between oil-based and water-based paints.
Oil Based Paint Versus Water Based Paint
1-Flexibility
Most water-based paints have a flexible structure, allowing them to be used on both soft and hard surfaces. However, oil-based paints have a hard structure and become rigid as they dry. Therefore, they lose their flexibility and may crack when applied to flexible surfaces.
2-Color Durability
The resins in oil-based paints are not suitable for light colors. Synthetic paints in white and similar shades tend to yellow quickly. On the other hand, water-based paints maintain their color durability across all shades. “Related article: what color should i paint my room?”
3-Covering Dark Colors
Oil-based paints generally provide better coverage than water-based paints. When applied over dark colors, oil-based paint tends to cover much better than water-based options. “Related article: paint over dark colors without primer.”
4-Odor
Synthetic paints are based on chemical resins, which emit odors for extended periods. The smell can linger for days or even weeks. In contrast, water-based paints either have a very mild odor or are completely odorless.
5-Drying Time
Oil-based paints, regardless of brand, dry much slower than water-based paints. You typically need to wait at least 24 hours between coats, which can slow down the application process. Water-based paints dry much faster, and waiting 2 to 4 hours between coats is usually sufficient.
6-Ease of Application
Water-based paints are generally easier to apply than oil-based paints. Fast drying, no roller marks, and low odor make them easier to apply and save time. “Related articles: how to paint with a roller without streaks? and tips for cutting in paint.
7-Cleanability
While many water-based paints can be cleaned, they are not as easy to clean as oil-based paints. Oil-based paints are much more resistant to stains and can be cleaned with many general-purpose cleaners.
8-OAvailability
Water-based paints are more widely available because they are more commonly used than oil-based paints. If you need a specific color or paint type, it may be easier to find a water-based option.
9-Paintable Surfaces
Oil-based paint can be applied over almost all types of surfaces and previous coats of paint. However, the surfaces that water-based paints can be applied to are more limited. Water-based paints adhere well to absorbent and matte surfaces. A primer is needed for other surfaces or to apply them over different types of paints. “Related article: latex over oil based paint.”
10-Durability
Both water-based and oil-based paints are durable, though oil-based paints are generally more durable than water-based paints. This can vary slightly depending on the manufacturer.
11-VOC Ratio
In the paint industry, VOCs (Volatile Organic Compounds) are often found in paints, varnishes, solvents, and similar products. The release of VOCs into the atmosphere has raised environmental and health concerns, as some VOCs can damage the ozone layer and negatively impact air quality. Oil-based paints tend to have higher VOC levels than water-based paints.
12-Shine and Smoothness
Both oil-based and water-based paints are available in glossy and matte finishes. However, oil-based paints are generally glossier and smoother. Glossy paint is not usually preferred for walls, but if you need a glossy, smooth finish, oil-based paints are a good choice.
