$29.00 CAD In stock, ready to ship
Key Features
  • Allows you to create a spectrum of viscosities - the more you add the thicker it gets
  • Create uniquely spongy, cake-like, aerated texture
  • Gives a matte surface finish
  • Maintains same levels of transparency and color
  • Fully intermixable with all Liquitex products
How to Use
  • Start by adding a very small amount of Liquithick to your color/medium
  • Mix well with a palette knife, adding more (up to 25% maximum) until you get desired consistency
  • Once applied, leave to dry for five to seven days for maximum strength and flexibility
  • As this is an additive – with no acrylic binders - do not add more than 25% to your color/medium and do not mix with other additives. This can cause excessive shrinkage, cracking and the acrylic film to break down
  • Do not use with any non-acrylic media

FREQUENTLY ASKED QUESTIONS

Other creatives have asked us...

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?

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.
