How Acrylic Painting Differs From Oil Painting?
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.
The reason oil paint is called "oil based" and acrylic paint is called "water based," is because the main binding ingredient of oil paint is linseed oil and that of acrylic paint is water.
Oil paint and acrylic paint differ in the time required for the drying process. The time needed by oil paint to dry is comparatively longer than acrylic paint, and may stretch from days to weeks and even years, depending on the ingredients used. This is due to the fact that oil paint dries by the process of oxidization, and acrylic paint dries by evaporation. However, this slow-drying property of oil paint allows enough time for the artist to work with the product longer, changing both the color and the final appearance.
Alternatively, acrylic paint is often chosen by artists who want faster results, since it takes only hours to dry. However, a slower-drying acrylic paint was introduced in 2008 by Golden Artist Colors, which combine the qualities of oil paints with the quicker drying time of acrylic, resulting in a paint that remains wet for a few hours on the palette under normal environmental conditions.
The use of oil paints comes with a few disadvantages. Turpentine, a solvent used to thin the paint and clean up the work area, has toxic properties and exposure should be minimized. Additionally, the canvas must be thoroughly primed before applying oil paint, and a removable layer of varnish must be applied afterward to the end 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.
