Other artists have asked us...
I live in Florida and I find my acrylics dry too quickly. Can I add anything to stop it?
Yes, we make four professional formulas to slow the drying rate down, which are perfect for warm climates. They each have their own benefits - take a look on their product pages.
My acrylic paint dries too fast. What can I do?
We suggest you first avoid adding water to your paint and minimize heat and air flow in your painting environment. Secondly. make use of acrylic mediums to extend the color, especially Slow-Dri Fluid or Gel, Airbrush Medium or Slow-Dri Fluid or Gel Additive. All of these will extend the open time and workability of your color. Remember that only one additive should be used within a color mix as combining additives can compromise the paint film stability.
What is an additive?
A good question. Additives are used to adjust the chemistry of acrylic paints, but they are very different to the rest of the mediums family. Most acrylic mediums contain high proportions of acrylic resins, but additives do not. With most acrylic mediums, you can add as much as you like to your color without weakening the stability of the acrylic film, while additives will dilute the strength of the acrylic film. This means that you need to be more careful about how much you mix into to your paint or it will have issues around drying, tackiness, separation and durability. Our four additives offer really useful individual benefits, so just make sure you follow the directions for use before starting to work with them.
