A pigment that has been suspended in an acrylic polymer emulsion s the source of acrylic paints. This is a mixture of two substances that defy blending. Until 1950, acrylic paints were not available for sales in the market. Acrylic paints are much sought after by artists & painters as they dry faster, unlike oil paints. They can be diluted with water. On dilution, the resultant paint looks similar to a water color painting or an oil painting, because they are prone to dry closer to the desired color. Normally this color is slightly darker. Water colors tend to dry lighter and the amount of lightning cannot be predicted. Artists, who are in the threshold of their painting career, face the same problem. Even though acrylic paints are diluted in water, infact, they become water-resistant once the work of art gets dried. Due to this nature, the artistic display can be preserved for a long time. Acrylic paints can be substituted for oil paintings because they dry faster - within one hour; sometimes in less than one minute. The duration depends upon the quality of the brand and the thickness of the coating.These paints can be mixed with extenders or retarders depending upon the necessity. By adding these products, the artists can extend the time of drying. Those who paint model figures tend to use extenders or retarders, the only hitch being thy take more time to complete the work. Acrylic paints are preferred by artists due to their permanency. Unlike oil paints which turn yellow due to ageing and oxidizing, acrylic paints have a longer lifespan, not showing signs of yellowing or cracking. As acrylic paints are versatile & challenging, artists enjoy using them. The painters get the desired look by changing the properties. The challenges can b surmounted by grasping the rudiments & planning the execution. One has to be extra-cautious while using acrylic paints as they dry faster. Take a little quantity and use it quickly. These paints are not removable. If solvents are us for removal, the entire canvas stands the chance of getting wiped out.
Blending can become very difficult after a short duration. Firstly, small segments can be painted and then you can move on to the next. The artist must have an idea of the minute details before proceeding further. For the best results, artist-grade gesso can be employed. Smoothing this on the canvas, sufficient drying time has to be allowed. This will bind the paint to the canvas very strongly. As these paints dry fast, blending becomes very difficult occasionally. Initially, paint in small areas and extend to other areas gradually. To slow the process of drying, a medium can be used. Occasional mists using a water bottle will keep it wet.Using additives, acrylic paints can be made thinner or thicker. They will change the thickness, the finish, the drying time & the transparency level. By adding water, you can thin it down. More water has to be avoided. An artist can use oil paints, chalk, pen, charcoal & other artistic media on their paintings without ruining the work they have already finished.
