Yep, was just wondering if you had tested it at all. Not trying to
promote it, just looking for more info. =)

I would not try PVA in general, from my (very limited) experience. I
don't know exactly what is different about Weldbond, but I know it does
seal concrete pretty well. I read an article some time ago that it has
to do with how they catalyze the polymer in it, somehow makes it alot
more water resistant. I would certainly not depend on it for underwater
use, but I want to give it a shot as a sealer for general use.

Hoping I can find a decent bit of latex for free (going to start
checking the landfills, etc) but until then, Weldbond looks reasonable.
Around $40-$50 for a gallon, which will cover about 2000 sq feet if
diluted to the recommended 5 to 1. Anyway, he just got his first
batches of paper and is going to borrow my old drill mixer for his
testing, so I will try to get him to give me results. Then maybe we
will all know a bit more. =)
