How To Repair A Damaged Or Torn Canvas Painting

wait for PVA glue to dry when repairing painting

Once you’ve got you patch applied and your piece of board laying flat on top of it, you need to place a weight of some description on top of that to keep everything is position and to make sure a good bond is formed between the patch and the original canvas. Once you’ve done that you need to let the PVA dry for at least 24 hours before doing anything else.

Once the glue had dried and you’ve removed the piece of hardboard and the weight your repair should look something like this.

The new canvas patch should be glued to the original canvas right up to the edges. If it isn’t, and the edges of the patch can still be lifted up, you’ll need to work a little more PVA glue under the unglued edges with match stick (or something similar), replace the board and weight onto the back of the painting, and wait another 24 hours for that to dry.

If you look closely you can see my repair was very successful. The canvas is even and flat once again, and all the edges are lined up well. You can however see that there are some stray/loose fibres, that’s not a problem, we’ll sort that out next.

To paint over the repaired area I mix a little Liquin Oleopasto medium into the paint that I use. Liquin is a medium that artists can add to oil paint and is mainly used to speed up drying times in every day oil paining, Oleopasto is just a much thicker form of this medium and helps to fill in any indentations in the repaired area as I repaint.

One of the keys to repainting a canvas like this is to repaint more than just the repaired area. Like with all painting, looseness/tightness of brushwork should match that of the rest of the painting, in my case other parts of my painting are painted with quite thick loose paint, namely the foreground wall and rocks, so this new more thickly painted area doesn’t stand out. You can see I continued repainting across the horizon line so that it all matched the newly repaired area – you might say the repair is hidden in plain sight. I used a palette knife to mix the new paint/oleopasto mix, and put the paint on quite thickly and deliberately uneven.

Here is the final result; a permanent repair and will last as long as the rest of the painting, and one that is unnoticeable unless one looks at the back of the painting to see the patch. Of course when selling a repaired painting like this it goes without saying you should tell the buyer.

  1. Hi Chris,
    I have a 19th century landscape painting that has a big crack/hole where the canvas is peeling back about 1.5 inches square, so quite large. It is in a large panel of blue sky, so hard to camouflage. I don’t know if a patch would work well since the canvas is quite dry and might crack if I try to flatten it. Any ideas on how to repair it? Is there a way to relax a dry canvas? Is re-lining the only option? If so, I don’t think I can do that myself, or do you know a good website that explains re-lining for amateurs?

    1. Hi Deborah, As your painting is a good age I would suggest contacting a local museum or art gallery, who should be able to put you in touch with a professional art restorer. These organisation use these services regularly. I wouldn’t suggest trying to release the canvas yourself on such an old painting ~ Chris

  2. Hi Chris thank you for your reply. I am afraid I chose the PVA and it does look good, all I have to do now is to retouch the paintwork using your advice, but will probably be nowhere as good as yours. It is a small area only, so will take my time. Once again thank you.
