How to paint on an already painted canvas ?

It's never obvious to find answers to our questions, and finally experience is the best professor. But I would like to introduce you, my problem.
I have a canvas that I had begun painting 2 years ago. needless to say the painting is dry and «*super-dry*». But I would like to paint an other subject on top for various reasons and notably because it's the only canvas on this dimensions. Dimensions which correspond to my new composition.

So question is: How can I go about it ?

My first idea was to try to clean the canvas with turpentine... No effect.
Then I have put down a coat of varnish diluted in 50 % with turpentine. But now I wonder if it's worth a try.


1*/Put down one or several coats of opaque colour will it be sufficient to hide definitely the previous picture ? I have doubt, and I don't want to realize the damage.

2*/Another solution would be to take the canvas off its support and to put it upside down. So, I have a new canvas that I should prepare to be able to paint again with oil.

3*/Finally, the last solution would be to take the canvas off its support and replace by a new linen one.

It seems that the third solution is the best for me. There is more work, but at least, it's a manner to rest on a sound basis

What do you think ?.

sand the old work carefully so your new work will have some grip. 320-400 grit sandpaper would still leave a smooth surface.

Re: How to paint on an already painted canvas ?

Or how about covering the canvas with gesso? after sanding?

Oh Yesss ! I didn't think of sanding. Thank you very much !
It is another solution which will be much quicker. I'm going to try !

The question of MissTillie is also very interesting. But is it necessary to cover with gesso on a sanded canvas ?

Re: How to paint on an already painted canvas ?

if you are thinking about sanding a painting be sure to take some safety precautions! you don't want those particles finding a way into you or your family's or pet's bodies.

boop

Sanding is the best way, but be careful what Gesso you use. You really shouldn't use Acrylic over an oil ground,which effectively you will have.
You should use an oil based Gesso, failing that you can use ordinary white oil paint ( I use Flake white thinned with a small amount of medium )
I've done this many times, to many ,with no problems whatsoever.
You might need more than one coat.

Thank you oldboy !
What medium can I use ?
The same that I used at the beginning, on the first paint ?
With the same dilution ?

Re: How to paint on an already painted canvas ?

I use a medium of 1 part Stand oil, 1 part Damar varnish, 5 parts turpentine as a good all round one, but I'm sure the the one you used originally will be fine.
The object is to make it easier to brush out. Only add as much as you need.
Best of luck.

Re: How to paint on an already painted canvas ?

I foolishly put acrylic gesso on an oil painting once and it NEVER dried.

You ran a big risk !

Re: How to paint on an already painted canvas ?

why cant you simply paint over the old painting? you said its *super dry*... I would just apply the new paint... and make your pretty picture.

It's because I used a lot of Prussian blue in the first painting and I would't like this colour to tarnish the layers of the next painting. I prefer trying to stop this blue by a light and very opaque layers.
