Question
I recently finished a landscape oil painting. I varnished it more than a week ago but it is still tacky. Why is it not drying properly? It only took two weeks for the oil paint to dry, it seems ridiculous that the varnish takes so long. I don't think that I used anything different than usual, but I never had this problem before. HELP!!

A: In order for an oil painting to dry and cure properly it takes a minimum of six months. True it was probably dry to the touch in just a few weeks, however, the under layers will hold moisture for months after. The thicker the paint the longer it takes. Usually, varnishing early will not cause any immediate visible problems, but if you live in a wet climate, or if the weather was particularly muggy on the day you varnished, the problems manifest much sooner. If the painting was done on a stretched canvas, try laying the picture face down in front of a sunny window for few days. If this does not work, or if the painting was done on another surface, you can remove the varnish with mineral spirits (gently, with a lint free cloth). Be aware that there will be some damage to your top layer of color and some repair will be needed.


Question
I just finished the best watercolor painting. I love it. How can I protect my work, my friend said that watercolors get ruined quickly.

A: Your friend is correct. Watercolors are notoriously fugitive. They should be framed under UV resistant glass with a mat to keep the work from touching the glass. It is also best to hang it away from direct sunlight. If you would like a dramatic demonstration of the effects of sunlight on art, do this simple test. Make horizontal lines in an assortment of colors then place a piece of white paper over half of the painting. Leave it in front of a sunny window for about two weeks. At that time remove the top sheet of white paper. You will see a dramatic difference between the two sides.

Any way to keep my pastel pictures from getting smudged?

A: There are a large variety of products available. the most popular being fixative aerosol sprays. Crystal Clear and Workable Fixative are great for 'fixing' pencil, charcoal and pastel drawings. The Crystal Clear will provide a strong final coat. The Workable Fixative is perfect if you think that you may want to re-work the picture.
