Well, it turns out it's actually very much like the most common white glue around. Gee, that glue we used in school, remember Elmer's Glue? It looks pretty much the same.
If you're just doing crafty projects then regular white glue will do. However, if you need your artwork to last a lifetime then you'll need the PVA.
PVA glue is used when you need archival quality. Meaning the glue will not yellow, it won't break down and will not affect the PH of papers, paints and other mediums that come in contact with it. It will last for many decades.
This is important for artists who sell their work.
PVA stands for Polyvinyl acetates.
What makes it so good and why it's recommended in all sorts of projects is this:
It's only toxic if you ingest it. So don't eat it.
It doesn't emit any stinky or harmful fumes.
And you can handle it safely without gloves.
It's pretty much acid-free which makes it ideal for archival work...In other words, it has a neutral PH.
It's pretty flexible.
It dries clear.
You can use it for paper, board, collage work, papier mache, book binding, crafts, wood, vinyl and as mentioned, archival work. It's even used in leatherwork!
This glue is really somethin'! :o)
