Acrylic Painting Techniques

The acrylic painting medium is a fairly new addition to the various painting mediums available to today's artists. It has been around since the 1950's and has been continually under development and refinement ever since.

Acrylic paint is highly favored amongst artists because of its wonderful versatility. It can be applied thickly as an impasto having rich texture or in washes mimicking the characteristics of watercolor.

Another likable characteristic of acrylic paint is its permanence. Acrylic paint is not susceptible to yellowing or hardening with age. With acrylic paint, the artist does not need to be concerned with the order the paint is applied or other special techniques that ensure the paint film remains free from cracking. So it can be said that acrylic paint is much easier to use than oil paint.

Yet another characteristic that invites new artists to this medium is its fast drying time. Since acrylic paint dries so quickly, colors can be applied and overlaid quicker than with oil painting.

There are however a few downsides to the quick drying time of acrylic paints:

1) The paint will not remain workable for very long, so you have to work quickly.

2) The fast drying time of acrylics can also ruin brushes if the brushes are not cleaned immediately.

3) Acrylic paint is not the best medium for direct painting outdoors, especially on a bright sunny day. Whatever paint you put out on your palette will begin to dry quickly and form a skin over the surface of the paint making it very difficult to work with.


Watercolor Effects

Acrylic paint works wonderfully as a transparent medium, similar to watercolor. Acrylics do have an advantage over watercolors. You can lay out a number of thin washes over one another without fear of disturbing the colors underneath. You must wait for one layer to dry completely before applying another of course. Once each layer dries it becomes insoluble in water. The only disadvantage to using acrylics as a watercolor medium is the difficulty in modifying the color. Once acrylic paint begins to dry it becomes rather difficult to work with. One of the biggest problems is the tendency for washes to dry with unwanted hard edges. You can avoid this problem in one of two ways. You can either dampen the paper before the paint is applied or you can use an additional brush dampened with water. Use one brush to apply the paint and immediately soften the edge with the other brush that has been dampened with the water.

Blending Opaque Colors

With watercolor effects, the acrylic paint is applied in transparent washes. With the opaque technique the paint layers are non-transparent. Blending opaque acrylic colors can be a bit tricky as you are kind of pressed for time. It is important therefore to only work on areas that you know you will have enough time to blend. To blend two colors, first paint a block of each color side by side on your support. Where the two colors join paint down that line with a clean damp brush to soften the edges. To blend the colors even further, move the blending brush from side to side or up and down, until the desired blending is achieved.

Sgraffito Technique

Sgraffito is a scratching technique. It got its name from the Italian word graffiare which literally means to scratch. Just as the name implies it involves scratching into the surface of the wet paint which reveals either the ground or layer of dry color underneath. There are a number of different tools that can be used for this technique. Tools like screwdrivers or the sharpened end of an old paintbrush handle should suffice. It really depends on the support you are using. For instance, a screwdriver may not be the best tool if you are using a panel as a support. The hard metal may damage the panel, so you would need to use a softer tool.

Using a Squeegee

A regular squeegee that you can purchase at any hardware or auto store can create some interesting effects when used with acrylic paint. First you would squeeze out some paint blobs directly along one edge of your support. You can layout whatever colors you wish. Then with one fluid motion you would drag the paint across the support with your squeegee, which will smear and mix the paint and create some very unique and interesting designs. You may need to alter your squeegee a bit as the rubber blade that comes with most squeegees may not be rigid enough to drag the paint. You can remove the rubber blade and in its place glue in a regular wooden ruler. This will give you a flat sturdy edge to manipulate the paint.

I hope you have enjoyed this article on acrylic painting techniques. Take some time today to experiment with these techniques and have fun. Happy Painting!

Acrylic Painting Basics

Today I am going to talk primarily about working with acrylics. Now, I would guess that oils are much like acrylics - at least in the way I like to apply them and in the end result I like to achieve. I know that they can be applied more like watercolors, too, but that's not how I prefer to use them. I will say right off that what I like most about the acrylics is also what I like least. They do dry very quickly and since patience isn't one of my virtues, that's what I like about them. However, on warm days, or if I want to paint outside, they really dry too quickly. But, I keep a spray bottle of water handy to wet them on the palette and I have found that some of the mediums you can buy really slow down the drying time, too. Plus, I like the look of the gloss medium added to the paints in many situations. Over the last couple of years I have started to use one of the "stay wet" palettes that can be purchased in most art supply stores or from catalogs, and they really do work wonderfully in the studio for extending the life of the acrylics you already have on your palette.


I don't buy any one brand of acrylic paint over the other, but do prefer some colors in one brand over another. For example, Sap Green in Liquitex is a lot different than Sap Green in the Dick Blick brand. I'm not sure why. I don't usually get the student grade paints in ANY brand, however. I like working with a limited palette, mixing my own colors, starting with an underpainting and using the color wheel when deciding on colors for my paintings. I think all of these will make wonderful starting places for topics in the future.

As far as painting surfaces go, I like to experiment there, too. I've tried a lot of different canvas types, and sometimes I gesso them myself, even if it says its already been done. I do like the portrait grade canvas better, especially when I am doing people, as it is much smoother. I also like painting on gessoed hardboard and even Pastelbord, which has recently become a personal favorite of mine! This is a rather unusual surface, but one you acrylic painters really should try if you haven't yet!

For examples of this fantastically versatile medium visit http://www.hughbanksart.com/ to view pieces done on the various surfaces discussed in this article.

Well, this is a start. I've enjoyed discussing acrylics in this very basic way and look forward to breaking down the different elements in more detail in the future.

Acrylic Paintings

Acrylic paintings are relatively new as acrylic paint for painting was first introduced around 1950. Acrylic paint has now become an essential element of the arts and craft market. Many artists consider acrylic paint as a viable option for oil paints. Acrylic paints differ from the conventional oil paints in terms of their physical and chemical properties and thus necessitates special care of acrylic paintings.
Typically, acrylic paints are of two types, namely water-based and solvent-based. However, water-based acrylics are more popular among painters. Acrylic paints dry quickly as compared to oil paints and may hardly require half an hour for the entire painting to dry. Acrylic films are not very hard and may easily gather dust and grime.

Various types of additives, such as stabilizers, defoamers, coalescing solvents, thickeners, and preservatives, are added to the acrylic paint to produce the desired results.

The chances of acrylic paintings cracking are relatively low as the paint is flexible and can withstand pressure. However, acrylic paintings may become very brittle and crack in freezing temperatures. Sometimes acrylic paintings may develop a gray veil on the surface or form a yellow discoloration over a long period of time.

Since acrylic films are soft at room temperature, dust particles can settle on the surface and become mixed with the paint, resulting in stained paintings. Protective framing can combat this problem up to a certain extent. Varnishes can protect the paintings considerably from scratches and dust. Many artists do not like to varnish their paintings. Another major problem faced by acrylic painters is that of mold growth and as of now, no perfect solution has been devised for this problem.

There is a wide range of acrylic paints available in the market. It is imperative for acrylic painters to purchased superior quality products as poor quality paints fade easily when exposed to ultra violet light.

Regardless of high standards of care and maintenance, many artists continue to use acrylic paints because of their fast-drying quality and versatility.
