Hello dear people from Mitra!
I have a question regarding mixed media basically.
If i have a fully rendered graphite pencil drawing on thick watercolor paper (with all details and deep shadows done, it has a lot of graphite on it) and i want to paint over that with acrylics , what is the best and safe way to do that?
Is it enough to just put a layer of a clear Matte Medium and than to paint over that with acrylics?
Or is it safer to first put a coat of Pastel, Charcoal Fixative ( it is Talens Fixative and it contains : Colourless resins, ethanol ) and i think it is workable fixative, and then to paint with acrylics and to use a acrylic matte medium in it?
Thank you in advance and i hope you are all ok and safe during these times.
Kindest regards
Marko Karadjinovic
Thank you Brian ! The only problem is that i cant get this fixative with B 72 in my country… Is it chemicaly ok and safe to put an acrylic matte medium over this graphite pencil drawing? I am not so concerned about smearing it , as i am about will it be chemicaly ok, so that acrylic will stick to it and the drawing will last?
Thank you once more
Thank you Mirjam! I just have one more question. Since i cant get any fixatives with B 72 component,as Brian adviced above, is it ok to use the Charcoal Pastel Concentrated fixative from Talens ( It contains Colourless resins, ethanol ) ? And then to work over that with acrylics? Or if it is not chemicaly ok and compatible , is it ok to put this Concentrated fixative and then to use Gouache maybe..?

Applying acrylic dispersion medium is perfectly appropriate but you may smear the graphite. I would think that applying a thin coating of a fixative would help mitigate this. If it were me, I would use one that is known to contain an acrylic resin making it eminently compatible. I believe that Lascaux Fixativ & Varnish and Krylon Crystal Clear Coating are still composed of B-72 in solvent. You could then apply the acrylic dispersion medium if you wish but this would probably not be necessary.
The rest of your procedure sounds fine
Hello Marko,
In our tests we found that solvent-born coatings tent to have better adhesion on graphite than water-born acrylic mediums. Graphite is also used as a dry lubricant and on heavy graphite application you would want to apply a coating that doesn’t just sit on top, but really penetrates through the graphite layer. Solvent based fixatives or varnishes penetrate better in general. If your drawing would consist only of a few lines, a water based acrylic medium or paint should be able to ‘bridge’ over that, but a heavy graphite application should be sprayed with a fixative or varnish first.
