You may need spirit gum alternatives for a variety of reasons:
Skin-safe spirit gum alternatives: If you’re having trouble finding spirit gum but still need something skin-safe, Pros-aide would be your best option (but it could be even harder to find), or you can look at using Liquid Latex.
Spirit gum alternatives that won’t work: You might have some white glue (PVA glue) or superglue (Cyanoacrylate) sitting around your house, and while they aren’t particularly harmful to put on your skin… they won’t work. Superglue may seem to work initially, but it’s so brittle that as your skin moves, it will start to peel off.
Spirit gum alternatives that just aren’t safe: Other adhesives might be great for costumes or crafts, but you should stay away from using them on your skin. These include everything from Barge Cement (which you shouldn’t even breathe in) to nail glue, which might seem safe because you use it on the body, but it should not be put directly on the skin (your nails are a little tougher).
