Acrylic Paint Information
Acrylic paints, a modern medium, are very popular due to their extreme versatility. There are great benefits for acrylic painting ideas, acrylic paint dries quickly, forms a tough, flexible film that's insoluble, and won't rot, discolour, or crack. fluid acrylics have high pigment concentrations, but lower viscosity than artist acrylics. They mix easily into acrylic mediums. Fluid acrylics can be used for watercolour-like techniques or sprayed with an airbrush. Mix them into heavy gels for impasto techniques. They also find many uses in crafts.
They are made from pigment, water and an acrylic binder, which forms a hard, clear film as the water evaporates.
It is this transparent film, reflecting light from the pigment inside it, that gives the acrylic colour its brilliance.
Acrylics dry very quickly, avoiding a tedious delay before painting further layers. The film is more flexible than that of other media and is unlikely to crack. Acrylics are resistant to water once dry, which means they can be overpainted without disturbing the previous colour. This means that colour cannot be dissolved with a damp brush as it can with watercolour.
To thin the colour, simply add water, or use an acrylic medium.
Acrylics become darker in tone as they dry, rather than lighter as with watercolour, so remember to allow for this effect when mixing colours.
They are a fascinating medium in their own right and are used by many professional artists in a variety of ways.
ACRYLIC "OIL PAINTING" TECHNIQUE
When used straight from the tube, acrylics have a consistency very similar to that of oils. Like oils, they retain the impression of the brush or knife, allowing you to create a considerable variety of surface or textural effects. Acrylics dry rapidly; it is usually possible to overpaint within an hour.
Even when dry, acrylics stay remarkably flexible, which means they can be painted on to most non-shiny, non-greasy grounds without cracking or splitting. The colour can be built up into thick layers and, provided that care is taken, the painting can even be rolled up when it has dried.
Acrylics do not require a coating of size before being applied to paper, cotton, linen or wood, as oil paints do.
Because they are water thinnable until dry, acrylic paint can be removed from brushes and palettes simply with soap and water. Be thorough, or paint can build up at the base of the hairs or bristles and cause damage.
Acrylic are weather-resistant (making them ideal for murals), and they paints retain their brilliance with age.
ACRYLIC "WATERCOLOUR" TECHNIQUE
By thinning acrylics with a small quantity of water and acrylic medium, a paint that can be used like transparent watercolour is produced. Alternatively, an additive such as Acrylic Flow Improver will give acrylics the consistency of watercolours while maintaining the strength of colour.
Comparison with watercolours
Since acrylics are water-resistant when dry, they can be overpainted without disturbing previous colour.
For the same reason, there is no need to frame an acrylic painting behind glass. For additional protection, it is advisable to use an acrylic varnish, which can be removed if necessary when the surface becomes soiled.
When using acrylics, always remember to clean your palette after painting to avoid a build-up of dry colour.
STUDENT GRADE ACRYLIC PAINTS
Have working characteristics similar to professional artist acrylics, but with lower pigment concentrations, less expensive formulas, and a smaller range of colours. More expensive pigments are generally replicated by hues.
Colours are designed to be mixed, although colour strength is lower.
Hues may not have the exact mixing characteristics of full-strength colours.More than any other medium, acrylic colours have opened up the world of art to multitudes of painters. The brilliance and durability of the colours, coupled with their simplicity and directness, make them an excellent choice for the newcomer or for those whose creative ideas demand immediate expression. Acrylic painters are unhampered by the sometimes laboured techniques of oil and watercolour painting, and the colours offer unbeatable convenience, fast drying time, incredible versatility and great permanence.
Surfaces to be painted on, need to be sealed: prepare canvas and boards with 2 coats of Atelier gesso, or work on sized watercolour paper.
