Buying Guide

Match medium to paint type

Choose mediums formulated for your paint (acrylic, oil, watercolor) to maintain adhesion and color integrity

Decide desired finish

Select glazing or gloss mediums for sheen, stencil butters for textured metallic effects, and pour mediums for fluid art

Check working time and flow

For pouring and glazing, prioritize additives that improve fluidity and leveling without excessive thinning or cracking

Consider permanence and archival needs

Use fixatives or archival-grade mediums when longevity and color stability are important for finished pieces

Look for multi-surface compatibility

If you work on canvas, wood, or mixed-media, choose products labeled for multi-surface use to avoid adhesion problems
