Liquithick Additive

  • Description
  • Directions

Liquithick by Liquitex is a thickening gel for use with water soluble acrylic paint and mediums. Used in small amounts, produces handling characteristics very close to that of oil or encaustic paint. At higher concentrations, can thicken paint or mediums to "cake" or sculptural consistency.

Drying time will be between 24 hours to 7 days depending upon amount of Liquithick added to paint or medium. Liquithick dries to a matte surface sheen and does not increase transparency. Paint and medium shrinkage will occur in proportion to the amount of Liquithick added. Archival Contains a unique polymer.

As this is an additive – with no acrylic binders - do not add more than 25% to your colour/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.

  • Start by adding a very small amount of Liquithick to paint or medium and mix well with a palette knife. The proper proportion will vary with color and desired effect.
  • Proportions of 20 or 25 parts color to 1 part Liquithick will change the handling characteristics.
  • Continue adding Liquithick slowly until the desired viscosity is achieved.
  • Add only enough for desired effect and do not exceed 1 to 4 ratio as excessive shrinkage and cracking may occur.

  • Excellent stuff

    If you like to work with thick gutsy paint then this is the gel for you. You only need a little (about a pea size amount to a table full of paint) to thicken up you paint. A good tip is to mix it together quickly. I use Liquithick with W&N artists acrylics and it work a treat. I contacted "ColArt" who own both W&N and Liquitex and they confirm that it is archively safe to use these products together. Paul Milner (Hull, United Kingdom) on 19 Jun 2012
