Understanding mediums
Mediums and auxiliaries let you control how paint behaves and how the finished work looks. From priming the surface to adding texture and protecting the final piece, the right medium makes a real difference. At Föndurlist you will find the essentials for acrylic and mixed media.
Priming with gesso
Gesso seals and primes canvas, wood and board so paint adheres well and colours stay vibrant. One or two coats give a smooth, slightly absorbent surface — the foundation of a durable painting.
Gels, texture and pouring
Gel mediums thicken paint, extend it and add body for impasto and texture, while pouring medium thins acrylics for flowing pour art and cells. Choose a gel for texture or a pouring medium for smooth, flowing effects.
Varnish and finishing
A final varnish protects the finished work from dust, UV and moisture and unifies the sheen — matte, satin or gloss. Let the paint cure fully before varnishing for the best, longest-lasting result.
Frequently asked questions
Do I need to prime my canvas with gesso?
Pre-primed canvases can be painted straight away, but an extra coat or two of gesso gives a smoother, more consistent surface and better paint adhesion. On raw canvas, wood or board, gesso is essential to seal and prime before painting.
What is pouring medium for?
Pouring medium thins acrylic paint to a flowing consistency for pour and fluid art, helping create smooth sheets of colour and cells without cracking. It keeps the paint film strong even when heavily diluted, unlike adding water alone.
Should I varnish my painting?
Varnishing is recommended for acrylic and oil works to protect them from dust, UV and moisture and to even out the sheen. Make sure the paint is fully cured first, then apply varnish in thin, even coats for a durable, professional finish.
