PostPosted: 0    Post subject: the Difference Between Acrylic Paint Grades

Every so often we get members who ask about the difference between craft acrylics and artist quality or model acrylics. I just came across a great article that takes the mystery our of acrylic paint grades.

For those of you who don't like to follow links I will C&P the content here. Wink


The Colorful Truth About the Difference Between Acrylic Paint Grades
(Drum Roll Please�)

If you�ll recall from where we left off last time; we have pigment and we have binder. Here comes the answer you�ve been kept in suspense over. The primary factor in different grades of paint is the ratio of pigment to binder.

Binder comes in several differing forms, some runny, some thick, some sticky, and some jelly-like. Regardless the type, binder is generally much less expensive than pigment which is often derived from pure and sometimes rare elements. Thus paint with more binder and less pigment in the mix will be less expensive to manufacture than one with a lot of pigment, and less binder.

This ratio is called the Pigment Load.
Lower grade paints have a low pigment load, which makes them less expensive. The very best grades of paint have a high pigment load ratio. This applies to virtually all paints on the planet�watercolors, acrylics, oils, exterior paint, you name it!

Though there are varying costs for the different types of binder, delivery and storage method; the biggest difference between �cheap� and quality paint -between inexpensive and quite costly, is usually all about the pigment load ratio. Of course at the upper end, the source, rarity, purity and type of pigment become primary factors in the price of the paint.

Acrylic Paint Grades

Artist (grade) acrylics are designed for painting on canvas, board, paper, panels, and other prepared surfaces. They are highly pigmented and and generally of a paste consistency thus preserving brush strokes. They can be used with a variety of painting techniques, including impasto and knife painting.

Iridescent, pearlescent, interference, and metallic (grade) acrylics mix conventional pigments with powdered mica (aluminum silicate) or bronze to achieve amazing effects. Colors have shimmering and reflective characteristics, depending on the coarseness or fineness of the powder added. Iridescent colors are used in both fine arts as well as crafts.

Student (grade) acrylics have working characteristics similar to the higher-grade artist acrylics, but with lower pigment concentrations, less expensive formulas, and a smaller range of colors. More expensive pigments are generally imitated by hues; that is, use of less pure mixtures of pigment to achieve the look of the purer high grade pigmenting elements. Student grade acrylic colors though formulated to be mixed; will have expectedly lower color strength. Hues also may not provide the same exact mixing characteristics of full-strength colors.

Incidentally, there�s no reason at all to spend the extra shekels on the higher-grade paints until you�ve used student grade to �flesh out� an image on your prepared surface. It generally takes several applications to fill in for the absent pigment anyway, so if you like the way a piece is turning out you can always get the artist grade to go over and complete the painting.

Fluid (grade) acrylics have high pigment concentrations, but lower viscosity (so they�re thinner) than artist acrylics. They mix easily into almost any acrylic mediums. Fluid acrylics can be used in achieving a watercolor-like technique. They are also an excellent choice when working with a sprayer or airbrush. Mix them into heavy gels for impasto techniques. They also find many uses among crafters.

Gouache (grade) acrylic is both a fluid acrylic and a craft acrylic. Like traditional gouache, it is opaque and dries to a matte finish. Unlike traditional gouache, it uses an acrylic polymer binder that is water-resistant when dry. Like craft acrylics, it adheres well to many surfaces. This makes it a favorite in decorative and folk art techniques.

Craft (grade) acrylics can be used on surfaces besides canvas, such as wood, metal, fabrics, and ceramics. They are used in decorative painting techniques and faux finishes, often to decorate ordinary everyday objects.

Scholastic (grade) acrylics use considerably less expensive pigments as well as dyes in formulations that are safe for younger artists, and cost effective for classroom use (i.e. finger painting). The color range is normally limited to common primary and secondary colors, and the actual pigments are unspecified. Because scholastic acrylics use dyes as well as pigments they won�t be very lightfast and so will fade from extended exposure to bright light.

Exterior (grade) acrylic, our last but certainly not least. Although I was kidding about exterior grade acrylic paints earlier they are often used as artistic medium and are available in in several grades or pigment load levels themselves. As is apparent by their name they are formulated to withstand outdoor conditions. Like craft acrylics, they adhere to a variety of surfaces. They are more resistant than other acrylic paint to both water and ultraviolet light. This makes them ideal for architectural accents, murals, outdoor signs, and many faux finishing techniques. Think about it for a moment; exterior acrylic paint is seen more than any other grade of acrylic paint. I�m not speaking of the homeowner�s annual or biannual preventative coat. The murals in public outdoor venues are definitely viewed on a much larger scale than the masterpieces in art museum collections or small galleries.

Did that help clear up any ambiguity regarding the differences in grades of acrylic paint? Hopefully you now have a much better understanding of the differences as well as some creative ideas about how to use the various grades of acrylic based paints. More options to add to the mix when devising the creation of your vision. Enjoy!

These rules also apply to all other artist mediums. But you don't have the problems of pigments fighting with each other in painting that you will notice when using pastels or colored pencils, for example, I have a plum colored pastel that refuses to cover red and orange, I asked my professor about this and he said "its the nature of the beast" some colors wont lay over others, it's something that has to do with chemistry, I am not a chemist nor do I make my own supplies so I do not have any explanation that is more detailed then that.

Golden sells an airbrush medium that works well for thinning heavy bodied acrylics, you could also use water to thin but it brakes the binding properties and the self leveling qualities are ruined, a 1:2 ratio works best for heavy bodied acrylics, one part acrylic paint, two parts Airbrush medium. Though DO NOT use it in combination to airbrush your pony. I know its made to be an airbrushing medium, but for some reason high end acrylics (fluid or heavy body) never dry, it always stays tacky, but craft paint works just fine in an airbrush.

When you mix the paint you will notice bubbles forming in the paint, these bubbles may be a problem if your painting a sculpted surface, I recommend putting the paint in a bottle, let it sit over night and the air can rise to the surface, then before use give it a little mix with the end of a paint brush and you are good to go.

Hope this helps Smile
