All about Acrylic Mediums
Our Acrylic Mediums collection is where you turn basic acrylic paint into anything you imagine. These Tri-Art and Art Noise mediums, made in Kingston, let you adjust texture, sheen, transparency, and working time so your colours behave exactly how you want them to.
You will find gessos and grounds (including black, neutral grey, clear, canvas gesso, and cold press watercolour ground) for creating the perfect painting surface. Polymer mediums in matte, semi gloss, and gloss let you thin paint without weakening the binder, build transparent layers, or use them as adhesives for collage. Gel mediums and self leveling gels add body or help create smooth, poured effects, while modeling paste builds sculptural texture right on the surface.
Specialty options like crackle ground, retarder, silk screening base, Final Finish varnishes, and re harvested glass, plastic, and copper cinder add unique visual and tactile effects. Use them with Tri-Art acrylics to glaze, pour, collage, texture, protect, and experiment.
Whether you are priming raw canvas, creating high gloss resin like finishes with Liquid Glass, or exploring textured abstract work, these acrylic mediums give you full control over the surface from first layer to final coat.
