Before framing your oil painting, it's essential to protect it. Oil paintings don't require glass frames, as the varnish will provide the surface protection. A simple molding frame will do fine. Colored or wood tones will work well. It's also a good idea to cover the canvas with a dust cover to prevent dust from settling and bugs from munching. It's best to use a high quality framing material, such as mahogany or pine, as these materials will preserve the painting for years to come.
When it comes to oil paint, the best time to frame your painting is after it's completely cured. While it may feel dry to the touch, it has not solidified yet. This happens through oxidation, a chemical reaction that takes anywhere from two weeks to several years. While a painting can feel dry, a proper drying period depends on the thickness of the paint layer. For this reason, most experts recommend letting your oil painting breathe.
A frame adds to the overall look of the oil painting. It defines the borders of the artwork and adds value. A poorly chosen frame can completely ruin the look of an oil painting, while a well-chosen frame will highlight its finest features. Although some artists choose to hang their canvases without frames, it is always a good idea to use an appropriate frame when you have one. You should also hang painting in a safe location.
