Herroo! So. I'm very new with EVA foam and so far, it went okay. I have the shapes, a good working contact glue and so on. But I'm now stuck with two issues. I also want to tell that I don't have a big budget! My first issue: My EVA foam fluffs up when I try to sand the edges, with both of my sand papers. (I believe it's 180 and 220.) What's the best way to fix the edges? My second issue: The coating for under the paint. I've tried some standard white glue that you can use in school, 4 spoons of glue with 1 spoon of water. I used two rather thick layers and it felt just fine, but I needed to sand it down as not every spot was even. As soon as I touched the glue with the sand paper, it just ripped apart. I removed all the glue for now. I've heard that quite a lot of cosplayers use white glue and I have no idea what I did wrong. Is there another cheap replacement for white glue for the coating, that's easy to get in the Netherlands?
