Should I Varnish My Painting?


Varnish serves 2 main purposes: to unify the appearance of a picture surface and to protect the surface from UV rays and dirt.

Varnish is available Acryic based, Oil based and Polymer based.

How to remove varnish - method

Some varnishes will have removal instructions on their label. The instructions on how to remove varnish on the Golden website offer good advice that on the whole, can be applied to the removal of most varnishes (providing you always use the appropriate substance for removing it with, as stated above). The advice that they give is as follows:

‘A good procedure for removing the varnish is to start with a soft, low lint cloth (50/50 cotton/polyester T-shirt material works well). Saturate this cloth in ammonia and lay over an area of the varnished surface. If possible, work with the painting in a horizontal position, on a table or floor.
If the work must be done vertically, as on a wall, a method would have to be devised for keeping the saturated cloth in contact with the varnished surface. In either case, to minimize evaporation, use a plastic sheet to blanket the saturated cloth.
Work in areas no larger than 2 square feet per application. Larger areas tend to become cumbersome and make thorough varnish removal difficult. Allow the saturated cloth to lie on the painting for 2-5 minutes. Before removing it, use a clean ammonia-dampened cloth to gently pat the surface to remove the varnish. Note: excessive force may damage the paint layers below the varnish. Repeat this process until the entire painting surface has been treated.
After a single treatment over the complete surface of the painting, some residual varnish may remain. Repeat the procedure, and continue doing so until the varnish has been sufficiently removed. Additional ammonia exposure may result in some swelling of the underlying paint layer’.

Please note that all fine art varnish manufacturers do recommend that removing varnish should be avoided if at all possible, as it can alter the appearance of the paint surface with improper handling. However there are occasions when there have been problems in the application of a varnish and the artist may need to remove the applied varnish in order to re-apply successfully.
