About Tri-Art acrylic mediums

Tri-Art Mediums - Polymer Medium Semi Gloss is part of the Tri-Art acrylic mediums range, designed to modify the look and handling of acrylic paint or to prepare and finish surfaces. Depending on the specific medium, it may be used to change gloss, transparency, thickness, texture, or absorbency.

Mediums like this can extend your paints, add body for impasto, create special effects, or act as grounds and topcoats.

At Art Noise, we consider mediums an essential part of a flexible acrylic setup, letting you get more variety from your existing colours.

How to choose and use this medium

Always start by checking the instructions on the container for Tri-Art Mediums - Polymer Medium Semi Gloss, since different mediums have different ideal uses and mixing ratios.

In general, add acrylic colour into the medium rather than the other way around, and test small amounts until you understand how it behaves. Use thinner, more fluid mediums for glazing and transparent layers; choose gels, pastes, and grounds for building texture or preparing surfaces.

Allow each layer of medium to dry fully before applying more paint or additional coats, especially when working thick. For varnishes and topcoats, only apply them to thoroughly dry paintings for the best clarity and durability.

Technical notes and safety

Tri-Art acrylic mediums share the same basic acrylic polymer technology as Tri-Art paints, so they dry to flexible, durable films. Many mediums appear milky when wet but dry more transparent, and finishes can range from matte to high gloss depending on the product.

Avoid ingestion and prolonged skin contact. Keep lids closed when not in use, do not allow the products to freeze, and store them away from extreme heat. Keep mediums out of reach of young children unless there is direct adult supervision.
