Hello,
I plan to paint onto ACM panels prepared with fine arts products (no industrial bonding primers). I have found Lascaux’s uni-primer, which is specially formulated to prepare non-absorbent surfaces such as polyester canvases and ACM. If I use it, they recommend applying two coats of oil ground on it after curing, but they don’t recommend any specific brand.
Are there any tests on this product to check its viability to prepare archival supports? Is the cross-hatch test sufficient to test adherence between the uni-primer and the ACM panel, as well as between the uni-primer and the oil ground? I am interested in Rublev’s lead oil ground.
Thank you so much for your time.
Hello there,
If it’s brushed aluminium surface, there should be reasonnable adherence of common gessoes. The cross-hatch test is reasonnable.
However since you’re not priming a flexible surface at all, why would you care to use a lead ground? It has no benefit in this situation.
Have fun,
Lussh
Thank you for your reply, Lussh.
My idea was to paint on coil coated ACMs, either directly or in a polyester canvas mounted on it. The aforementioned primer is said to be specifically formulated to adhere to non-absorbent materials like polyester, hence my interest on it. I have not considered brushed aluminium, as I think delamination issues may appear over time, am I wrong with this assumption. My interest is to work with the most archival support I can prepare with today’s materials, so I am open-minded as long as this criteria is met.
As Lascaux advised to apply an oil ground onto their uniprimer, I thought about lead oil ground, aware of it being most likely overkill. I prefer to prepare and excesivelly robust support than to fall short.
Any suggestion and advise is welcome, thank you.
if you are open mind, then how about using oil tempered hardboard called manonite and apply acrylic gesso as ground, then you can start oil painting directly on top?
that is very common practice and considered as archival as it is rigid support and oil tempered hardboard is strong material itself.
what other expert is thinking this support?
