I am about to tear my hair out! Does anyone else have a problem with canvases warping? If so, what do you do to correct it? Thanks for any input.

Never had a canvas warp! Before or after painting? I have had them have sink marks before painting but a little spray of water on the backside and sitting in a warm place to dry usually smoothes that out. Sorry couldn't help.

Trine, are these canvases that you purchased or are you building them yourself? Sometimes the really large ones that you can buy will warp if you don't add crossbars to the back. If you're building your own, you will probably need to start using thicker bars. When I stretch anything over 20", I have to use 1.5" bars so they don't bend or twist when the canvas is pulled tight over them.

I have had the frame of a canvas warp (I don't know if it was warped before I painted on it or not), and so I pulled the painting out of my inventory. I'd love to know if there is a way to fix it!

Cheap canvas OFTEN warps. Why? They arent dried properly during production and they change with the humidity of travel, your environment, etc.

Look for "Kiln Dried" stretcher bars and you will have better luck!

They are more expensive, but a happy customer is worth more than saving a few bucks. Dont want anyone calling me later to say my painting warped.

Sounds like you might need to have it re-stretched. It's not has bad as it sounds. I too would look for kilned dried stretcher strips. I prefer to stretch all of my canvases so i ahve seen it all when it comes to jacked up stretcher bars.

Here is a solution that worked on a gallery wrapped canvas (24" x 30" x 1.5" d). Buy a 1/2" thick MDF partial board at Home Depot and have it trimmed to the canvas size. You will need some 1" wood screws and washers that fit the head. What you want to do is attach the board from behind and pull the painting up tight to the MDF board. Even if the painting is skewed, you can pull it over to fit the 90 degrees of the MDF board. Let it set for about a month and about 99% of the warp will be gone. Tip: Before attaching the MDF board, use a damp rag and soak the stretcher boards a bit (good and damp). Keep the painting in a very dry place so it will not mildew, as the bars dry, the train to the flat surface. Another tip is to be sure to drill some pilot holes in the MDF board and make sure the are centered in the stretcher bars. The washers keep the wood screws from sinking into the MDF board as the bars dry. One more tip: Now, when buying a canvas, I'll lay it on the floor and see if it is flat. You will be surprised how many are not level, even top dollar canvases.

Oops: The previous post should have read " as the bars dry, they train to the flat surface. "

Wow!! Thank you everyone for all of your great feedback. It's also nice to see that I'm not alone and this had happened to others.
