Hello,I have just found this site and scrolled trough all the messages, and am delighted to find information about strappo as I am just trying to practise this technique for the first time. I read the long explanation about strappo (I think of about two years ago), and I would like to ask an few things more about it. I am busy making a small fresco with the purpose of taking it off the wall by method of the strappo technique. How long do I have to wait, iow. how dry does the fresco need to be, and what would happen if I do not wait at all and add the cow bone glue and the canvas etc. to the still fresh (wet) intonaco?
And another question is, can I make the taking-off-the-fresco easier by adapting the intonaco layer (more sand perhaps or another kind of sand?)
thanks for offering the opportunity of asking questions.
Kind regards
