Global Colours Gesso Medium is recommended for surface preparation and sealing. It is flexible, fast drying and permanent.
Gesso Medium is best applied with a broad brush or cardboard wedge, onto a surface free from dust and grease. Dilute with water as required to allow for absorption into surfaces or varying porosity (e.g. concrete, wood, canvas, plaster, etc.). To achieve a smooth surface apply several thin coats with light sanding in between.
This medium is compatible with the range of Global Colours acrylics and other mediums, working together to create a highly versatile painting system for all artists.
