Product Information

If it’s a good painting it may be worth the effort, and it could be a learning experience to practice re-stretching. This is what is meant when someone says you need to ‘bang your stretchers apart’, they mean to tap the stretcher bars in their centres, one at a time, away from the middle of the canvas. After you have expanded the canvas a bit then push your wedges in to hold them apart, like a doorstop wedge holds open a door, or a keystone hold a masonry arch in place. I find this allows the wedges to be pushed in further before you start tapping on them and gives a tighter canvas. But I usually do need to do some more pushing with the wedge to finish the job. Of course you could un-wrap the corners and remove the staples, and as now stretched, the canvas will not distort and you could then push the wedges in for more tension. I realise this is not an ideal solution, but these canvases are very popular and we have sold thousands of them without this issue being raised (until now!) so we feel this proves that the original tension is usually excellent.

If you have already tried these then I’m afraid you will need to re-stretch the painting. You might try first just to re-stretch the the 1/4 of the painting that has the problem, it might be enough. But you will probably need to remove it and stretch it completely to get an even tension. It is good practice to try to get your bars to spread apart a bit before you start tapping in your wedges, rather then just using the wedges themselves to push the bars apart. Best practice is that you should do all the movement of the bars by pulling and tapping on the bars to expand them and only inserting the wedges after you have expanded the frame. They are called keys or retainers because they fit in the space you have created to retain the expansion of the bars. This image has not been loaded.

The keys (wedges) are not designed to force the corner overlap open, but rather to sit in the gap to keep the tension as the bars try to close the gap.This image has not been loaded.
