The quality and longevity of artwork greatly depends on the quality and correct usage of the materials. I sincerely hope that my background in science, and extensive research in pigments, paints, painting mediums, varnishes, supports, and their preparation and usage, will help my artwork to withstand harsh Australian climate.
However, even made with the best art materials, a painting should not be kept outdoors, placed in direct sunlight, exposed to high or low temperatures, stored in moist, dump or mouldy environment, accumulate dust, or be subjected to physical damage or chemicals. It is better not to hang the artwork on the exterior walls of the house (when the painting’s back is facing outdoors through the wall). Unless the wall is extremely well insulated, it can let some moisture and temperature changes through and eventually affect the painting on the inner surface of the wall. As a result, the back of the painting may get mouldy, and, over time, the damage may extend to the front of the painting. If the exterior wall is the only possible place, the back of the painting should be checked, cleaned from dust and aired from time to time.
What I use
Supports: stretched and primed canvas of appropriate density or MDF boards with 2 coats of quality gesso. The boards have a coating on the back surface to protect the painting from mould and mildew.
Paints: Archival oil paints made in Australia by Chroma Australia Pty Ltd and formulated to be flexible, stable and not crack over time.
Mediums and solvents: non-toxic or low-toxic odourless Archival mediums and solvents also made in Australia by Chroma.
Varnish: Gamvar varnish, developed in collaboration with the National Gallery of Art and made in USA by Gamblin Artists Colors Co.
