Acrylic Paints

Acrylic paints are one of the newest painting mediums, being introduced as 'recently' as 1955. They have come a long way since then, with an ever-widening range of paints and associated art materials.

The acrylic paint technique thus offers both the new and experienced artist a very versatile method of painting.

What Are Acrylic Paints?

A water-based medium, the usual texture and consistency is similar to oil paints. However, unlike oils, you can get acrylics in various densities.

These range from an ink-like consistencythin enough to be used in airbrushesthrough various degrees of 'flow' very much like oil paints, to the consistency of soft cream cheese.

This allows really heavy 3D (impasto) effects.

Various substances are available to be added to the paint to create all sorts of textures.

Or you can use your own, such as plaster or sand, for a further variety of textured effects.

All the brands and thicknesses can be thinned back down using water. Some artists I know actually use thinned down acrylic in a pure watercolor style. This givessubtly different but important qualities

Pros & Cons of Using Acrylic Paints

As in all painting, the acrylic paint technique has benefits and drawbacks. The good things are that:

• It is easily diluted with water, so there's no need for special thinners
• Brushes are cleaned with soap and water
• It dries fast - often within minutes - unlike oils which can take weeks or even months
• Once dry, you can instantly put additional layers on top without ever muddying the ones below -as can happen with watercolour paints
• You can paint on a wide range of surfaces including art canvas, watercolour and other types of specially formulated oil and acrylic paper, wood, various types of board or even use room walls
• Colours change very little from their wet to dry state - unlike watercolours - so the strength of colour you see first is what you end up with
• It washes off clothes and carpets when wet, just by using soap and water
• There is no solvent-type smell, as there is with oils and turpentine
• Thinned acrylic paint makes an excellent underpainting if you're using oils
  

However, like all paintng mediums, there are downsides when using acrylic paint. These are mainly around one of its main virtues... its quick drying properties. Here are some things you need to consider:

• Drying so quickly makes it difficult to subtly blend paint, as you can with oils - when painting a cloudy sky or portraits for example

• You have to keep all your brushes moist as you are painting. Never let them dry with acrylic paint on the bristles or you'll end up with a nice-looking set of short garden canes.

• Paint which dries on the blade of a palette knife is very hard to get off. This can leave a film which may adversely affect the ability of the knife to make a smooth mark

• You need a special palette to stop your paints drying out as well. These aren't cheap for what they are.
• If there's any grease on the painting surface, acrylics will not adhere, unlike oil paints

• Acrylic paint tends to be quietly abrasive and soon takes its toll on softer brushes. Try using it with a small nylon 00 watercolor brush, for example, and you'll be lucky to get more than two or three good sessions out of it

• If acrylic paint gets inside the ferrule and dries it's almost impossible to get out without damaging the brush hairs. What then happens is the dried paint makes the bristles spread and the brush loses much of its value as a quality tool

• Don't leave the tops off tubes of acrylic paint, the contents will go rock hard in no time. If this happens, you throw them away. Full stop

• Some brands of acrylic paint have small tops on the tubes. They are extremely difficult to get off as the paint dries in the threads.

• If you have problems gripping small items, you may want to choose tubes which have large caps - or buy a good pair of pliers!

• Acrylic paint is a close cousin of PVA glue and as such, quite an effective, if somewhat colourful, adhesive.

Painting Surfaces

Despite the disadvantages we've looked at, acrylic paint is really a very versatile medium. This is particularly evident when looking at the surfaces you can actually use on which to paint.

As a direct alternative to oils, acrylic on canvas is an excellent choice.

Make sure though, the canvas is coated with an acrylic, rather than oil-based primer, or gesso (a product specially made for the acrylic painting technique). Acrylics won't stick to an oil-based primer.

You can use various papers and watercolor paper is particularly good, even for the thicker paint.

Although it doesn't have to be primed, it is helpful to stop paint soaking in to the surface and risking leaving a patchy image.

This also applies to painting on boards such as Masonite and MDF. In fact you can exploit the primer or gesso properties by putting it on with a coarse house-painting brush.

If you only have household latex-type emulsion paint, use that instead, for a cheap primer.

Add a touch of acrylic colour to it (Raw Sienna is good) to give a warm base to your picture.

Paint first in one direction, then when dry, lightly in the other. With care you can create a nice texture that approximates to canvas, which will show through your picture.

Alternatively try stippling the primer on for a different texture.
