GOLDEN Extra Heavy Gel Matte 8 oz

GOLDEN Extra Heavy Gel Matte is a very thick matte acrylic medium that dries to a wax-like finish. It serves multiple purposes: thickening, glazing, extending, altering sheen, and increasing translucency of acrylic paint. The gel’s range of consistency allows it to be used for glazes, extending paints, building texture, and acting as an adhesive for collage work. This 8-ounce jar is suitable for studio use and experimentation with impasto techniques.
GOLDEN Extra Heavy Gel Matte 16 oz

This 16-ounce version of GOLDEN Extra Heavy Gel Matte maintains the same wax-like finish and thickening capabilities. Ideal for artists seeking larger batches for extended projects, it supports thickened applications, glazing, texture building, and adhesive uses in collage work, with the same semi-transparent to opaque potential depending on layering and dilution.
GOLDEN Extra Heavy Gel Matte 128 oz

The 128-ounce container offers extended value for studios with frequent use of thickened gels. It preserves the same wax-like matte finish and versatile functionality—thickening, glazing, extending, sheen adjustment, and translucency management— while supporting large-scale textures and durable collages.
GOLDEN Heavy Gel Gloss 128 oz

GOLDEN Heavy Gel Gloss is a thick, clear drying acrylic medium used to thicken, extend, and alter the sheen of acrylic paint with a translucent to glossy finish. It supports glaze work, texture building, and collage applications, offering a different finish spectrum from the matte gels for versatile results across painting styles.

It mirrors the gel family’s versatility for glazing, texture build-up, and collage adhesive use, with a focus on a glossy finish that can intensify light reflection in the painted surface.
Buying Guide
Key purchase considerations for extra heavy gel mediums include finish (matte vs gloss), dryness and translucency, and working time. Matte gels typically yield a wax-like, non-reflective surface ideal for thick impasto and collage adhesion, while gloss gels provide a clear, shiny glaze and deeper translucency. Size and value are practical factors for studios with high-volume needs; large containers offer cost efficiency but require ample storage. Compatibility with acrylic paints, dry time, and archival stability are important for long-term projects. Consider testing on a scrap piece to compare texture, translucency, and sheen before committing to a particular brand or size.
Additionally, assess how the gel interacts with various brushes and tools for texture can be controlled with brush marks, palette knives, or stencils. Some gels double as binders for collage, so their adhesive properties may influence layering sequences. If you aim for multi-finish results in one piece, selecting both matte and gloss gels can help achieve nuanced effects with minimal layering. Finally, verify storage recommendations to preserve gel consistency over time and prevent separation or hardening.
