Tacky Glue: an experiment

Following up my post on my Sealing EVA Foam Experiment, I have undertaken to expand my knowledge of Tacky Glue and its possible use to replace Plasti-Dip as my primary undercoating for EVA foam.

Experiment: 

Using a scrap piece of EVA foam I experimented with different thicknesses of tacky glue to try to determine what thickness would be best to create a shiny, metallic type surface out of EVA foam.

Materials: Elmer’s Craft Bond Tacky Glue  and Rust-oleum Bright Coat Metallic Finish spray paint.

Woodglue? Plasti-dip? PVA glue? Sealing EVA Foam on the Cheap: an experiment

There is a lot of talk on the internet about different ways to seal EVA foam.  I’ve always used plasti-dip, a product readily available in the USA in spray form or “dip” form.  A whole suit of armor could easily use 5+ cans, and at $7.00 or so a can, that can add up.  Honestly, because of cost, I’ve never put on as many coats of the stuff as I needed to to get a really clean, shiny surface.

I’ve seen it recommended on the internet that you can seal foam using a mysterious substance called PVA glue.   What is PVA (polyvinyl acetate) glue?  Well, I haven’t really determined that.  Some people say it’s woodglue. Other’s say it is white glue.  Still others say that it is a specially glue that you can buy to bind books.  Honestly, I’ve googled and googled and haven’t come up with a definitive answer.   So I went to the craft store, and then to the home improvement store to buy some of this PVA glue, but not one bottle of glue said PVA anywhere on it.

In the past I’ve tried sealing foam with both woodglue, and modge-podge, and both produced cracked undesirable results.    But maybe I was just doing it wrong?  Some people recommend diluting the glue, 1:1, 1:3, 1:10 – I’ve seen all variations.    And then recently, I saw someone recommend using a combination: woodglue topped with plasti-dip.

So before launching into another project that would inevitably cost me $50 in plasti-dip, I decided to run my own experiment.
