Use of varnish over acrylic or PVAc paintings
I am currently doing a PhD on the artistic use of synthetic varnishes (often acrylic) over acrylic and PVAc paintings and the conservation challenges associated with these varnishes.
I want to gather information about artists who have varnished their acrylic or PVAc paintings and their intentions (if known), as well as the condition of the varnish (has it yellowed, greyed, become milky, imbibed dirt?).
I would also like to get idea of treatments undertaken by conservators (if any) to remove these varnishes. What varnish removal method(s) were tested and used? How successful was the treatment?
I will be extremely grateful if practicing conservators could take the time to complete this questionnaire:
https://forms.office.com/e/AKYAHFwVPy.
The intention is that it will not take more than 10 minutes, but the more detailed information you can provide the better.
Thank you in advance!
Best, Laura
