Be careful which acrylic paints you choose to mix with each other. Lower grade pigmented paints can separate from higher graded ones.

Mixable Acrylic Paint Pigments

It may seem redundant to know that acrylic paint pigments are mixable with one another. However, depending on the amount of pigmentation used to make an acrylic paint can render it unmixable with other acrylics of varying consistencies. What does this exactly mean to one who paints?

It means that if you use a pre-thinned acrylic paint with any other that is greater in thickness due either to filler or pigmentation, the two paints can separate from one another during the drying process or application. In other words, it is sort of like mixing water with oil. There may be those who disagree, but to try and mix a cheaply made acrylic with a more professional grade, and you will see the breakdown.

Not all acrylic paints are made the same. This also applies from one brand to the next one. When choosing acrylic paints to mix, it is best to pick the same brand for each pigmented color. As an example, you would not want to use Reeves acrylic paint to mix with Grumbacher acrylics. Why? They will not hold well together.

This is mainly due to the different quantities of Gum Arabic used to make each brand of paint. For the motor enthusiast, it is similar to using SAE 40 oil with 10W-5 oil in the same engine. This will cause variable wearing of the motor parts, causing irregularities in the catalytic converter, and end up making the vehicle backfire. In the end, this wearing down can cause the muffler to blow out.

So what does that have to do with pigmentation in acrylic paint? Lower quality acrylic paints tend to have more filler in relation to pigmentation and gum Arabic. This means they will not be as brilliant in color when they dry. It also means that the layering technique will not be as effective as it would be with acrylic paints higher in pigment.

Testing will need to be done before painting a full-fledged painting with different brands of acrylic paints. Paper can be the cheaper of the materials to utilize. Masonite, or hardboard as some call it, may be a better option to pre-test varied brand names. Different pigments react in various ways to one another. The outcome may not be pleasing when inferior acrylic paints are used.

Better acrylic paints may be fine to cross-mix with one another. Again, do some testing before making it applicable to your painting. Make a list of which paints mix well with others, and those that should be avoided. This pre-screening of acrylic pigments will be of great benefit for future paintings.
