These paints are water-based so they are easy to work with and there is no need for dangerous solvents. The paint film formed by these paints is very strong and flexible. The most important characteristic of acrylics is the fact that they can be used thin and liquid as watercolor or thick, right out of the tube like oil paint. Acrylics are used for so many different surfaces and purposes that the grades and types used should be based on the type of work being done. A 40- foot wide mural should not be done with tubes of paint.
Acrylics come in tubes the same as oils.
There are various sizes, but the most common is about the same size as the standard oil paint tube. It also comes in large tubes for bigger painting. It can also be purchased in tubs and even buckets of various sizes for mural painting. For mural painting, check to see that the brand is lightfast, lime-resistant, and weatherproof. Most acrylics will meet these specifications, but not all.
