All varnishes increase the chemical and physical resistance, and protect against ultraviolet light. The varnishes improve the colour intensity and increase the durability of the painting. Ensure that the surface to be treated is clean and apply using a suitable varnish brush. The varnishes contain a petroleum distillate. Do not dilute the varnishes, or mix with water. Dried varnish can be removed with white spirit. Clean materials immediately after use using white spirit.
