ART TIP: How to Fix a Dented Canvas

Have you ever unwrapped a new canvas to discover that it was a little dented? Or perhaps you have one that's gotten dented because something was leaning against it?

Here's how to fix it:

1. ​The canvas itself is probably stretched a little loosely to begin with. You can use "painter's keys" to tighten it — also a good idea (to be addressed later) — but that won't fix a little dent.
2. Turn the canvas over, and spread a little water on the back of it, in the dented area. You can use a mister bottle if you like, or just pour a little water directly on it and spread it with your hand.
3. As the canvas dries, you'll notice how it tightens up. The dent should tighten up and disappear.
4. If the canvas is still a little dented, repeat (you may need to use a little more water, too).

Remember: never stack anything against a canvas or a painting that will dent, scratch, or pierce it — and then you won't have to worry about repairing it later.
