Oil paint is a slow-drying paint that contains particles of pigment suspended in a drying oil. Acrylic paint is a fast-drying paint that has pigment suspended in an acrylic polymer emulsion. Even though acrylic paints can be diluted with water, once they are dry, the resulting product is water resistant. A finished acrylic painting can have the appearance of a watercolor, an oil painting, or some other unique look, depending on the percentage of dilution with water, gels, or pastes.
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.
Over a period of time, oil paint can become yellow and brittle and start cracking, so it is recommended to follow the principle of "fat over lean" to avoid cracking; which means that each successive coat of paint must have a higher oil to pigment ratio.
The average artist will appreciate the versatility of acrylic paint, but because of its faster drying time will not be able to use the wet in wet technique and also blend the colors that can be done in oil painting. If a slower drying process is desired, retarders should be added to the paint which will allow the addition of water so that the paint becomes more workable.
