Lumin's Workshop Foam Clay starts out as a foamy putty like clay that stretches and blends back into itself beautifully. Once fully cured, the foam clay dries into a high density, extremey light foam which can be cut, sanded, painted, and glued to your costume. Also works great for sealing seams or imperfections in EVA foam builds. Available in 3 colours - white, grey, and black - but it is fully paintable once dry.
Once the Foam Clay starts drying, it may become hard to smooth lines out, so we recommend rubbing it with a TINY bit of water to get rid of seams. Once your piece is finished, leave it to air dry - the bigger the piece, the longer it will take*. The cured foam clay pieces do not need to be heat sealed but we do recommend priming before painting!
* We recommend giving the clay around 48 hours to cure before painting, if your piece is large, the centre may not be fully cured yet. This is normal and you can prime and paint your piece before it's cured on the inside! But you must wait for your piece to be fully cured before cutting and sanding through the surface layer.
