Q. I have a client whod like a wall mural done in her kitchen using colored pencils. The wall is currently painted with latex semi-gloss. Whats the best application technique, and how can I seal the work for maximum durability?
A.This is a difficult question to answer. In the first place, the durability of your work will be a mystery because the lightfastness of many brands of colored pencil is still questionable, as theres currently no standard for lightfastness accepted throughout the industry. Secondly, whether the colored pencil would stick to the latex underpainting is another serious question. If you thoroughly sand the wall beforehand to give it sufficient tooth you could be reasonably confident of the adhesion, but thats going to be a lot of work. Finally, keep in mind that any varnish coating capable of withstanding the constant cleaning a kitchen wall undergoes might yellow so much as to obscure or alter the image. Frankly, artists varnishes arent formulated to be scrubbable.
My advice? See if you can persuade your client to accept a mural painted in acrylic emulsion paints, which are better suited to this type of application. If thats the way you go, heres a basic preparation process. Lightly sand the clean wall, wipe it thoroughly with a damp rag and let it dry, then prime it with two coats of a high-quality acrylic emulsion gesso. Then paint your painting. To protect it, give the dried painting a coat of acrylic emulsion gloss medium and allow it to dry, and follow that with one or two coats of an acrylic solution varnish.
Lastly, Id caution your client to be extremely careful in the regular care of the surface of this painting; no matter how clean his or her kitchen is, the wall will get dirty sooner or later. It should be gently washed with a cloth just dampened with a mild hand soap and water, then rinsed with a cloth dampened with plain water. Im afraid there are no guarantees, however, that this procedure wont damage the delicate surface of such a painting, even if its varnished.
