Several painting classes LA include the topic about the advantages and disadvantages of using Acrylics and Oil Based Paints. The pros and cons are put into this article in order to lead the beginners to decide on the kind of paints they would use when they begin their tasks.

It is better to first understand both paints by their meaning and descriptions. Oil paint is a type of slow-drying paint that is made of particles of pigment hanging in the drying oil, generally known as linseed oil. The viscosity of the paint could be changed through adding a solvent such as turpentine or white spirit, and varnish might be contributed to improve the glossiness of the dried film. While, acrylic paint is quick drying paint that contains pigment suspension in acrylic polymer emulsion. Acrylic paints can be diluted with water, but become water-resistant when dry.

Talking about the benefits of each, acrylic dries quickly. It can be mixed with water or mediums / gels. The brushes used in here are washed with water. As soon as dried, it may be over painted without disturbing underlying layers. It can be used thickly (impasto), like oils, or perhaps in thin washes, like watercolor. It's water-resistant, so excellent for murals and works as adhesive that is so great for collages. On the other hand, oil dries slowly, allowing lots of time for you to do the job and to combine colors. The percentage of oil to spirit dictates the drying period. Once dried, it can be over painted without disturbing underlying layers. It's rich, heavy colors which maintain their high intensity when dry. It can be used thickly or in thin, smooth washes. Then there's the status element, oils to be what the old experts used.

While for drawbacks, acrylic dries extremely fast, though operating time could be increased with the addition of retarding medium to paint or squirting water on a painting. It is completely waterproof once dried, it cannot be removed by rewetting the paint. It is rather hard to take out from a brush if it's dried in it. Except when used in thin washes, colors dry a bit darker than when applied. For Oil, it can be mixed with solvents thus, the need to work in a well-ventilated area as it can be too smelly or messy. It is slow-drying, thus, the need to think about working on several paintings at once. It needs to put it off several months to make sure a painting is dry before it can be varnished. Brushes must be cleaned with white spirit or equivalent solvent. Water-based oils are produced by a few paint manufacturers.

Painting classes LA, debates whether or not to use acrylic paints or oil paints, which is better than the other. It's an ongoing subject with various artists and painting classes. Both acrylics and oils have their pros and cons, supporters as well as detractors. It might be great to refer on the pros and cons mentioned above so that the selection is yours to make.
