Does that include Lascaux 360? I read in another thread that a grumbler glued two sheets of Coroplast together with Lascaux 360.I use coroplast by the pallet- it has wonderful properties but it is an AWFUL mounting substrate.
It is very difficult to get adhesives to stick.
My own testing would take way more time and money and failure than what I'm doing now, which is researching by consulting you experts, filtering through the advice and then conducting my own tests. This way, I can save a lot of time, money, failure and experimentation by avoiding the mistakes that you experts have already made. (However, I have been looking at other Web sites and going to my neigbourhood art supply store during this process to look at some of the materials being discussed here, and to ask questions of the staff.)You are making things way too complicated. Why not do your own tests? Buy a sheet of coroplast and also natural (tan) gator and try it yourself. They are usually both available from the same supplier.
There's no gatorfoam at the neighbourhood art supply store. Why should I spend time, money and effort trying to find it and maybe have to order some to be delivered from out of town, only to find out later (because I didn't research it thoroughly to begin with) that it's not the best way to go? Researching in this forum first is supposed to streamline this research and development process for me.
Why do you say that I am making things way too complicated? As always happens when one asks for advice, one gets a variety of choices and much conflicting advice, which makes it hard to decide what's the right thing to do. As an example, in this message and elsewhere in this thread, you're contradicting the advice of Wilhelm Imaging by your criticism of varnishing canvas giclees. (Your advice is the opposite of WIR's advice, and opposite to the advice from another grumbler about using gatorboard.)
As always happens when one asks for advice, people have different and think that their advice is the best advice and that I should ignore conflicting advice.
You additionally have to keep in mind that what works for one grumbler might not work for another. (One man's drink is another man's poison.)
Also, I'm using an unorthodox approach to picture framing/mounting, so that implies that I'm attemping something which requires extra effort for me.
It's crucial that I not screw up with this process, because I don't want it to fail and have complaints about my canvas prints being defective. As an example: When I was at the art supply store a couple of days ago, a sales clerk told me that a famous artist (who I know of) came into the store and mounted one of his canvas giclees with double-sided tape onto Coroplast. That method is contradictory to advice that I'd get here, because the tape may eventually damage the canvas, and then the artist might get complaints from the customer. I want to avoid such mistakes by learning how to do it properly.
I think I'm close to finding a solution, though, because I've eliminated many options because of steering that I've gotten in this thread and the research I've done by looking at Web sites and checking at the art supply store.
RobertJust be sure to do the "scientific" Premier Imaging Products "official" test (as demonstrated on their website) to determine if you put the overcoating on thick enough by folding a corner and seeing if the canvas cracks. If it does, put on a 4th (or 5th) coat........
Also, as demonstrated in the video, be sure that when you wash off your roller, you roll it on a concrete driveway to be sure that the overcoating has been thoroughly removed.
