Canvas

Special products such as Copper and Zinc Napthenate are used for the preservation of canvas. Oils, bitumens and waxes are used for impregnation and waterproofing.

All these materials possess the necessary flexibility to withstand constant folding and unfolding.

Preparation
Remove gross contamination.

Paper

Should you wish to paint over wallpaper or lining paper, oil paints should not be used because they harden and become brittle with age.

Water based paints should be used instead, although wallpaper adhesive remains water-soluble. This means that the paper automatically bubbles due to expansion and softening of the adhesive when painted over with water based paints.

This should not be a cause for concern as the bubbles usually disappear when the paint dries.

Preparation
Dust the paper and make sure that it is adhering firmly.
