Lumin's Workshop 300g Ultra Light Foam Clay is a super lightweight and highly versatile material. It's perfect for adding cool details to your foam armor and other DIY projects. This foam clay starts as a foamy, putty - like substance that stretches and blends together smoothly. As the surface begins to dry, it can be a bit tricky to smooth the lines, so just add a tiny drop of water. Once your project is done, let it air - dry. Remember, larger pieces take longer to dry. Once fully cured, it turns into a high - density foam that you can cut, sand, heat - form, and glue onto your costume. It doesn't need heat - sealing after curing, but priming before painting is a great idea! Warning: This foam clay may freeze in cold weather. When fully frozen, it'll turn rubbery and solid, not smooth and silky even after thawing. We suggest waiting about 48 hours for curing before painting. If your piece is large, the center might not be fully cured, which is normal. You can prime and paint before the inside is fully cured, but wait for full curing before cutting and sanding the surface layer.

Using Lumin's Workshop Ultra Light Foam Clay is easy! First, start using it as a foamy putty to add details to your foam armor or other DIY projects. If the surface starts to dry and it's hard to smooth the lines, just add a little water. After you finish your piece, let it air - dry. Bigger pieces will take more time. Wait about 48 hours before painting. Even if the center of a large piece isn't fully cured, you can still prime and paint it. But don't cut or sand the surface until it's fully cured. Be careful in cold weather, as the clay may freeze and become rubbery and solid. After it thaws, it won't be as smooth as before. And don't forget to prime the cured clay before painting for the best results.
