Our take on the GAC 100 Acrylic Painting Medium

Golden GAC 100 is a fluid acrylic medium used to thin heavy-body acrylics and build transparent glazes without losing film strength. It mixes with any brand of acrylic and dries clear, so it extends paint rather than replacing it. Artists reach for it when they want more open, brushable paint or soft layered washes. It is a workhorse additive rather than a stand-alone varnish or retarder, and it competes with generic flow mediums on consistency and predictability.

Pros
  • Thins heavy-body acrylics while keeping the film strong
  • Works with any brand or style of acrylic
  • Dries clear, so glazes stay clean
  • Squeeze bottle with applicator cap gives drop-by-drop control
  • Simple one-bottle additive for flow and glazing
Cons
  • Not a retarder, so it does not noticeably slow drying
  • Over-thinning can weaken adhesion and color intensity
  • Not a substitute for a final varnish

What reviewers say

Artists who use GAC 100 treat it as a dependable flow and glazing medium that behaves the same across paint brands. Most praise how little it takes to change paint consistency. Complaints center on drying speed and on how easy it is to over-thin.

What people mention
  • ConsistencyPraisedUsers say a small amount makes heavy-body paint flow and brush out more smoothly.
  • GlazingPraisedArtists report clean, transparent layers when it is mixed generously into paint.
  • Drying timeCriticisedSome users note it does not slow drying, so wet-in-wet work still sets quickly.
  • Over-thinningMixedReviewers warn that too much medium can leave paint weak or washed out.
