gesso on a oil prepared canvas??

[sabine]

I suppose this can't be done, but hope to be wrong :lol:

can you glue a coton cloth ("maroufler" in french, I didn't find the english term...) on a oil (or acrylic) prepared canvas? That would save me a lot of time...

Did anyone experience this or heard something about it?

I don't think so. The layers of different types (oil, acrylic, glue, etc.) tend not to adhere very well.

Maroufler? Is it a kind of cotton canvas? "Duck" is the word for a stiff, unbleached heavy cotton canvas.

Some time back, I experimented with gluing canvas to well cured oil paint.I tried every kind of glue that I could find. My conclusion was that no glue will stick to dry oil paint. My advice is: use what artists of the past have used that have proven workable over the centuries. I was told in years past, that acrylic grounds were quite fine, but they are too young to be classed as archival. Now I am hearing that acrylics are falling apart. Stick with what works over the test of time.

Thanks for answering :grin:

I found "to strenghten" for maroufler, but I don't think that's the right word... its the operation consisting in gluing a piece of coton on a tensed canvas...

I've got a book that recommands that for larger formats: lighter than pannel, stronger than simple canvas...

the thing is that I have a few unused canvas that I had prepared for oil and acrylic... I would really like to reuse them and it would save me all this part of the preparatiohn and material...

I thought as there would be the coton in between maybe it would be OK??

but I guess you're both right, I will stick with what works... (even if it gives me more work!)

I was really interrested by those informations about the miseries of ageing acrylic, by the way!

I read about that recently, but I don't remember where. It might have been on this forum.

Conservators used to put cloth on the backs of old canvas to strengthen them. It's called "lining".

I've not heard of gluing cloth to canvas to strengthen it, although I have heard of gluing linen to *panels* before gessoing them.

[sabine]

that's it alexandra: gluing linen to a panel except in this case it would be coton on a prepared canvas...

[Alessandra Kelley]

I guess the word for that would be "reinforcement". It means adding something to something to make it stronger, like soldiers to an army unit or extra bracing to a wall.

"reinforcement" should be it - thank you for improving my english vocabulary! ;)
