How to Paint with Acrylics: My notes: Richard W Linford, fineartamerica


I enjoy painting with acrylics. They are versatile. They are modern. Acrylics are made of a pigment, an acrylic binder, and water. Acrylics are polymer-based. They are like plastic.Acrylics dry fast so you can overpaint and layer quickly. They clean up easily with water. They do not easily crack.
They are water resistant when dry. Acrylics dry darker as they dry. They retain their brilliance with age. They are weather resistant.

Disadvantages and Advantages: Some disadvantages of acrylics are: They dry so fast.They make it difficult to “blend” a painting.

Some advantages of acrylics: You can paint a number of paintings quickly. You can use all oil based painting techniques. You can use glazing.
You can thin acrylics. You can paint over acrylics in rapid succession. You can paint impasto style as well with acrylics. You can paint oil over acrylics.

How Acrylics Work and are Used A simplistic explanation of how Acrylic paints work is: The water evaporates; A translucent film remains. The paint reflects light and creates brilliance..

Acrylics are thinned - With water and With acrylic medium.

They can be used: From the tube like oil paints; Thinned with water like water color; And can be placed on and used from a palette like oils if you keep them wet.

Watercolors and Oil Paints and Acrylics: Compared to water colors: Water color by contrast can be dissolved with a wet brush and or water.
Water color fades as it dries. Acrylics darken as they dry. Water colors need to be framed behind glass. Acrylics do not.

Compared to oil paints: Acrylics can be painted over in 60 minutes or less. Acrylics can be painted on many surfaces and won’t crack or split.
Acrylics don’t require sizing of paper, cotton, linen, wood while oils do. You can clean your brushes with soap and water which you can’t do with oils unless you use a water based oil. Acrylics and oils do not mix. Acrylics are water based. Oils are oil based. Water and oil don’t mix. Oils take a great deal of time to dry – weeks -- months -- years.

Cleaning brushes and palette: To clean your brushes and your palette: Use water. Use a liquid hand soap diluted or straight. Clean the base of your brush thoroughly to avoid color build-up.

Technique for Using Acrylics like Watercolors: The technique for using acrylics like water colors include: Thinning your acrylics with water; Thinning your acrylics with acrylic medium. This thinning creates a transparent “watercolor.” You can use an additive Acrylic Flow Improver to give your Acrylics the consistency of water colors.

Technique for Using Acrylics and Oils Together: The technique to use Acrylics and Oils together: “Separate your tubes of oil paints from your acrylics.”
Otherwise, you will run the risk of grabbing an oil instead of an acrylic or vice versa. With oils you normally paint an underpainting or rough sketch using oils and it takes a long time for the paint to dry. If you use an acrylic underpainting you save an immense amount of drying time.

Acrylics adhere well to canvas or board or paper or most any other dry and oil free medium.

Use a wash on the canvas. You make your wash by diluting a mixture of the paint in water. Use a large brush and rough sketch your outlines.
Block in the areas you are going to paint. Experiment with thin acrylics drawing and painting. Then apply the oil over the underpainting.
[Or finish your painting in acrylic.]

Make sure your acrylic underpainting is perfectly dry.

“Use turpentine or a mixture of turpentine and linseed oil to ensure that your initial coat of oil paint is thin. “ … extend the underpainting using oils.”
Texture:

Using acrylics, you can build up textures in minutes. You can use your palette knife or various brushes or other tools. Then you apply oil paint over the texture. You can then “apply thicker and more substantial layers of oil to your painting.”

The reason to apply your oils thinly at first is so you can follow your underpainting lines.”

Rubbing back: Take a clean cloth and rub back the oil to reveal layers of acrylic.

An “acrylic underpainting supports and adds depth and luminosity to your oil painting.”

Finishing: To finish your acrylic painting: You may want to use an acrylic varnish to give additional protection. Although that is absolutely necessary.
