  • Using Pigment Markers on Acrylic GessoApproveRejectUn-ApproveSubscribeUn-Unsubscribe

    Acrylic Art Conservation Topics Grounds / Priming Solvents and Thinners Varnishes
    Question

    Hi all,

    I would like to explore using W&N Pigment Markers which seem to use a good selection of commonly used ATSM I/II pigments but are available in a marker form. I already have a few of their water colour markers which I like, but there are many more colour choices in their Pigment Marker range.

    However they are ethanol based and I understand that alcohol/ethanol would act as a solvent on acrylic gesso? I know they can be used on Yupo and other alcohol resistant plastics, but I am looking to add clear Gesso which contains silicia make a more toothy suface. A non-absorbant, more pastel ground like surface.

    Considering that with the markers I would be making rubbing motions I'm not sure what I could put over the Gesso to protect it from the alcohol. Are there any varnishes that are not soluable in alcohol but will resist a rubbing motion?

    The only thing I could think of was a layer of water based polyurethane (but I am concerned about yellowing).

    Any ideas or suggestions?

    Thanks,
    Richard

    I would first just try this out on a sample canvas covered with acrylic dispersion ground to see if this is really a problem. It is possible that you would be happy with the results. If it is a problem, regalrez varnish (sold by in a few proprietary names by paint manufactures, just Google it) is not readily soluble in ethanol and would be a likely choice. First try this to make sure but it should work fine in theory. Water-based polyurethane varnishes do yellow quite appreciably, I would not use them for this purpose.

    ​Thanks Brian, I ordered a trial set which arrived today after I posted this thread. To my surprise when using the pigment markers or the blending marker it doesn't seem to cause any effects on the acrylic gesso.

    So it looks like you were right! That makes things a lot easier for me then :)
