Oil paint is made up of particles of pigment suspended in a drying oil, and takes much longer to dry relative to other kinds of paint. Acrylic paint is a paint that includes pigment suspended in an acrylic polymer emulsion with an added quality of fast drying. Acrylic paint, even after being diluted with water, becomes water resistant once dry. Depending on the proportion of dilution with water, gels, or pastes, a finished acrylic painting can have the look of a watercolor or an oil painting, or some other unique blend
Linseed oil is the main ingredient that binds oil paint; on the contrary, water is the main ingredient that binds acrylic paint. Hence, we can say that oil paint is “oil based” and acrylic paint is “water based.”
Acrylic paint and oil paint require different lengths of time to dry. Oils take relatively more time to dry, typically several weeks, depending on the ingredients used. This is because oils do not undergo the same process of evaporation that water does when exposed to air. Rather, oil paint oxidizes into a dry solid. This property causes oil paint to dry very slowly, giving the artist time to blend colors and adjust the final product.
On the other hand, acrylic paint remains the choice of those artists who believe in quick results, since only a couple of hours are required for the paint to dry. Nevertheless, a slower drying version of acrylic paint was developed by Golden Artist Colors in 2008, which combined the qualities of acrylic paint with the longer drying duration of oil paint, allowing the paint to remain wet for a few more hours on the canvas under normal conditions.
When we use oil paint, we need a solvent such as turpentine to thin the paint and clean up the work space, which has its disadvantages because turpentine has toxic qualities. An additional step that is required is that the canvas must be thoroughly primed before being painted on, and afterward a removable protective layer of varnish should be applied to the finished product.
During the passage of time, oil paint can look yellowish and turn brittle and crack, which makes it wise to apply the principle of “fat over lean” to maintain a smooth surface – each coat of paint should have a higher oil to pigment ratio.
Acrylic is typically more versatile in nature to use for the average artist, although because of its faster drying time, the painter is not able to blend colors or use the wet-in-wet technique available to oil paint. Retarders can be added to acrylic paint to slow the drying process, allowing water to be added to make the paint more workable.
