Jeremy, is that one-coat of gum over the
pt/pd?

Subject: Gambling PVA Size for gum over
pt/pd; Was: Re: Suggestions for sizinggum in an apartment
It seems like we usually don't get too many updates on the
questions asked here so I thought I would provide one. I started printing
using the Gamblin PVA Size diluted 1:1 as size for gum over pt/pd prints. How
did it work? Better than I would have ever hoped. It took me 20 minutes to go
from a dry, unsized pt/pd print to dry, sized paper ready to coat with
gum.
The Gamblin PVA Size makes for a glossier print than my gelatin
sized gum overs, which is a plus to me.
Here's a scan of my first
attempt using this stuff:

I can get out of a weekend out of town I'll get down to some serious tests
this weekend, but at the very least (if the store does have Gamblin PVA Size
as they said they did) I'll try sizing and printing with the Gamblin PVA
Size tonight on a small print.

It works well with Fabriano EW.
Dilution ranges from full strength to 1:2,
and some use it before the first layer while others lay down a layer
first, then size, esp with a cyanotype first layer. Some even use a
diluted coat between layers, you'll have to see what works for you, if at
all.
Katharine, I wasn't referring to you when I
mentioned people using the wrong product. There was a forum where folks
were obviously misunderstanding and using PVA adhesive instead of gum
arabic, thinking that that is what would prevent staining. It was a very
mixed up affair ;-)
Oh...and I still owe you an email. I've been
very busy lately and am behind on my replies...apologies.

Thanks for the update Katharine. Fabriano Artisitico is a crisper
surface, but the Arches Platine and BFK Rives (I have some of that
hanging out) aren't so the Gamblin PVA Size may work for me. I'm
definitely one to just give it a go and see how it works for me
anyway--tried doing gum over without a size last night, but the stain
was unsightly.

one who tried it (and yes, I did try the right product) and didn't
like it. I used it at full concentration, since one person who
uses it successfully applies it at full strength, and it gave me
a hard, shiny surface that the gum didn't stick to well, and even
diluted by half it was still too plastic-y for my taste ; any less
didn't provide enough sizing. In a conversation here, (too
hurried to look it up in the archives) I think we agreed that it
probably depends a lot on the paper; Jim uses a more absorbent
paper and the stuff soaks in more, while I use a paper with a very
crisp surface (Arches bright white) and the stuff sits more on top.
So I think it's probably a matter of playing around with
concentrations until you get a combination that works with your paper.
While I didn't like it for my own work with my own materials, I
would definitely recommend it for people looking for a nontoxic size;
I know it works like a charm for several people, and I certainly
wasn't intending to discourage anyone from trying it, simply reporting
my own experience with it.
