Oil-Based Paint vs Latex Paint Oil-Based Paint vs Latex Paint

Water serves as the medium for a latex polymer emulsion which is the binder in latex paints, while linseed oil is the binder and medium for oil-based paints. Hence, latex paint is regarded as water-based, while an oil paint is better known as oil-based.   

Take note that oil paints usually turn yellow as it dry, age, and oxidize, which need a removable layer of protection like varnish. On the other hand, latex paints have no known record of appearing yellowish, altering or cracking surface since it was acknowledged in market. For that reason, many people prefer to use latex paints for its durability and affordability.

The Difference

The major functional difference between oil paints and most latex paints is the inherent time for drying. Oils need more time to combine colors and put on even glazes on under paintings. This slow down drying characteristic of oil is seen as a benefit for some techniques. However, in other aspects it hinders the artist attempting to work fast. In 2008 Golden Artist Colors Company introduced a slow-drying latex paint with working qualities comparable to oil, yet indistinguishable from usual latex paint once totally dry. This new latex paint can stay wet and practical on a palette for quite a few hours as well as during days with normal conditions.

Water-Based Advantage

The quick evaporation of water of regular latex paint can be slow down through the utilization of latex retarders. Generally, these retarders are glycerin or glycol-based additives. This retarder addition slows the water evaporation rate, and permits additional water to be supplemented and the paint is completely workable, until the latex paint layer has dried and the latex retarder has run off the film.

Because of latex paints more consistent drying time and more flexible nature between colors, you can have the "fat over lean" rule for oil painting. It has more medium that must be applied with each layer in order to prevent cracking. The speedy drying of latex paint tends to daunt the combination of color, as well as the exploit of wet-in-wet technique exclusive for oil painting.

Oil-Based Paints Benefits

Oil paints necessitate the use of solvents just like turpentine or mineral spirits to slim the paint as well as clean up. Generally, these contain some stage of toxicity and are regularly found unpleasant. Oil-based paint films become enhancing yellow and frail with time. It can even lose much of the paints suppleness in some decades. In addition, the "fat over lean" rules should be used to make sure that the paint films become hard-wearing.

Oil-based paint has an elevated pigment load since it is capable to absorb considerably more pigment rather than latex paints. It is because linseed oil contains smaller molecule rather than the latex paint does. Oil-based paints offers a less clear refractive index compared to latex paint dispersions, conveying an irreplaceable "look and feel" to the ensuing paint film. Not the entire oil pigments are obtainable in latex paints. For instance, Zinc White and Prussian blue are not accessible because of chemical incompatibility together with the latex binder. Nevertheless, there is nothing like fluorescent oil paints besides the one available for latex paints.
