Amsterdam - Acrylic Mediums

Acrylic Mediums

Extend color or build thick layers without changing paint flow

Thickness determines everything when you're building sculptural texture or extending paint for glazing work. Amsterdam offers three viscosity levels, standard, heavy, and extra heavy, each formulated to maintain paint's working properties while adding volume or transparency. Standard gel extends color for glazing without thinning the consistency; heavy gel enables thick single-stroke applications with visible brush marks; extra heavy gel holds extreme peaks and knife work for dimensional effects. Each formula comes in gloss or matte finish, letting you control surface sheen while modifying body.

These gels function equally well as adhesives for collage elements, from paper fragments to heavier found objects, eliminating the need for separate glues in mixed media work. Formulated to work across acrylic brands, they integrate seamlessly whether you're extending student-grade paint or modifying professional colors. The 250ml tubes feature practical screw caps that seal reliably between sessions and hang-able packaging that maximizes studio storage.

Non-hazardous formulation cleans from brushes and palettes with plain water, keeping your workflow straightforward. Students appreciate the approachable price point for experimenting with texture; experienced painters value the consistent performance across techniques from impasto to transparent layering.
