Cosplay tutorial pet peeves
- EVA foam and Styrofoam are not the same thing. This is important because CA glue and spray paint will melt Styrofoam if applied directly, but not with EVA foam.
- Styrofoam is a trademarked brand for extruded polystyrene foam. HOWEVER, when most people use styrofoam in the US, they mean expanded polystyrene (EPS), which is the bead-like foam you often seen in craft stores. Extruded polystyrene (XPS) is most commonly seen as insulation board.*
- EVA foam stands for “ethylene-vinyl acetate” and is simply a category of foam. Craft foam/foamies in the US is a kind of EVA foam, not a separate thing.
- Rubber cement and contact cement are not the same thing. Contact cement is much stronger and designed to permanently bond materials together.
- Sintra (trade name for closed-cell PVC foamboard) can release chlorine gas when heated up. Please do not heat form Sintra without proper ventilation and safety gear. Please do not suggest heat forming Sintra without noting the risks. The same for PVC tubing.
- CA (cyanoacrylates) glue is a strong adhesive commonly known as “super glue.” Not all glues marketed as “super glue” are CA glue.
- Unless it’s been marked food safe or for oral use, DON’T PUT CA GLUE ON THINGS GOING IN YOUR MOUTH. Or liquid nails. Or nail polish sealer.
Tl;DR: Precision and clarity is important when writing tutorials because “I glued my foam and painted it” can result in a finished prop or a melted mess.
*You can also get EPS insulation board. You can probably still use it for props, but it’ll be easier to sand and shape XPS board.
