Rheotech Gesso by Art Noise

Rheotech Acrylic Gesso is a professional-quality primer made with 100% acrylic and calcium carbonate for outstanding strength, adhesion, coverage, and flexibility. It creates a slightly porous ground suitable for both acrylic and oil paints, drying to a bright, matte, opaque white finish with a slight tooth that enhances colour vibrancy and can be sanded smooth.

Part of the Rheotech range — Canada’s most trusted student and studio acrylic line — this gesso delivers professional results at an accessible price. It will not lift, crack, or chip from the surface, making it a reliable foundation for any painting project. Can be tinted with Rheotech Acrylic Colours to create custom coloured grounds. At Art Noise, we recommend it for classrooms, studios, and anyone who wants a dependable, truly white primer.
