Acrylic painting techniques
From Wikipedia, the free encyclopedia
Acrylic painting techniques are different styles of manipulating and working with polymer-based acrylic paints. Acrylics differ from oil paints in that they have shorter drying times (as little as 10 minutes) and are soluble in water. These types of paint eliminate the need for turpentine and gesso, and can be applied directly onto canvas. Aside from painting with concentrated color paints, acrylics can also be watered down to a consistency that can be poured or used for glazing.

[edit] Preventing paint from drying out
Acrylics are often preferred because they dry faster on canvas than oil paints due to their polymer base. Unfortunately, this also affects the time acrylics stay moist. A trick to keep paints from drying out is to spray a light mist of water over them occasionally [2]. Moisture-retaining palettes also increase acrylic paint drying time, and can be substituted with a shallow container, a sheet of grease proof paper, and piece of wet watercolor paper [1].
[edit] Creating fluid paints
Fluid paints can be used like watercolors, or for glazing and washes. To create a more fluid texture, water is added to the paint. The ratio of paint to water depends on how thick the glaze is expected to be. An opaque glaze or paint consists of more paint than water, and will give a more solid color. A translucent glaze or paint will be the opposite, consisting of slightly more water than the opaque version, and will have a smoother texture. Translucent glazes show more of the colors underneath the paint compared to opaque glazes. Artist Keri Ippolito advises that the paint should be watered no more than 50 percent or the paint will not stick to the canvas [3]. After mixing the paints, allow time for the air bubbles to rise to the surface. This will be crucial in many techniques, especially in pouring paints.
[edit] Painting glazes
Acrylic paint glazes are often used to create more depth in an image. These types of paints are light enough when brushed onto canvas to show the layers underneath. This technique is commonly used to create more realistic images. Light colored glazes also have softening effects when painted over dark or bright images. It can be difficult to get the right liquid consistency for glazes. Golden Acrylic Glazes simplify the mixing process by arriving ready-to-use in the bottle. Created to give the artist more time to work with the paints without having to worry about the paint to water ratio, this brand of glaze is commonly used in place of mixing acrylic glazes by hand [5]. It is best to wait for each layer to dry thoroughly before apply another coat. This will prevent the paint from smearing or leaving unwanted smudge marks. After the application of several layers, rubbing alcohol can be brushed or sprayed on to reveal colors from earlier layers [4].
[edit] Pouring paints
Pour painting is an innovative way to use acrylic paints to create an art piece. Instead of using tools like brushes or knives to create a piece of art, fluid paints can be poured directly onto the surface and the canvas tilted to move the paint around. Pouring paints allow for the colors to blend naturally as they come in contact with each other. This technique can be done either one color at a time, or with multiple paints to maximize color blending. Pour painting can also be done with oil paints, but because those paints take a longer time to dry, the piece would have to be done over an extended period of time, or with wet paints [3].
