Lumin's Workshop Ultra Light Foam Clay is Now Available!

Are you tired of sanding layers upon layers of foam? Don't have space or time to carve out those organic details? Does your prop need to stay as lightweight as possible? You'll want to read this; your crafting prayers have been answered!


We’re excited to announce Lumin’s Workshop Ultra Light Foam Clay is now available through Arda Wigs USA!

Brought to you by Australian cosplay supply company Lumin’s Workshop, this revolutionary material is sculpt-able, mold-able, and air cures into a high-density, ultra lightweight foam. Once cured, your object can be cut, sanded, primed, and painted just as you would EVA craft foam, no specialty tools required. Less dust, less mess! Sculpt your piece on top of a base to save material and give your project added strength.

Check out how Arda Wigs Canada utilizes Lumin’s Workshop Foam Clay to create organic shapes and details on these horns.


Lumin's Workshop Foam Clay blends together while soft, and can be used with a small amount of water smooth when the clay surface begins to cure. Give your piece at least 48 hours to fully cure for the best results. Keep in mind that thicker pieces may take even longer to cure on the inside, so hold off on sanding or cutting until you know the piece is solid all the way through! Lumin's Workshop Foam Clay is available in grey, white, and black, allowing you to choose the foam that best suits your project overall.

How much working time do I have before it starts to cure?

The more you work the clay, the harder it will become. Generally speaking, you have anywhere between ten minutes to half an hour of working time depending on the consistency you require for your project. If the surface has dried too much, add a little water to re-soften (not too much, or it will affect the curing process). Use a soft, finely textured sponge with water to help blend seams together.

As the clay cures, the surface may become even smoother than when it was wet, helping to blend out any minor imperfections. 

After 48 hours you can usually safely paint your object. If you want to cut into the surface or sand it with sandpaper, we recommend letting the object cure to air from all sides for 7-10 days.

How long does a container last for?

As long as you keep the lid on tight, it should last at least a year. 

What molds can I use?

Silicone molds work great for smaller projects, combined with a touch of talcum/baby powder to assist in demolding when cured (make sure to take the piece out so the foam touching the inside of the mold has time to completely cure in air). Plaster/gypsum molds will help the clay cure as well.

Can I use it as a gap filler for my larger foam-smithing projects?

Absolutely! Press the clay into the gap and leave a little extra on the outsides to help with bonding, then simply sand down the excess once cured.

What kind of paint can I use?

All sorts! Spray paint and acrylic paint react the same to the cured foam as your standard EVA foam. While heat sealing is not necessary, a good primer will keep the foam soaking up the paint. We recommend Flexbond.

Can I heat up the foam to shape it once cured?

Yes, just remember foam heating safety while doing so. Heat the object just enough that it will flex, and make sure to heat the object evenly. 


How flexible is it when fully cured?

While this material is foam-like and flexible, it is not completely indestructible. Thicker objects will be more durable than thinner objects when fully cured. For thicker objects, if the material has not cured fully on the inside, you will able to bend and squish the object more easily. However, you may accidentally dent or rip open the cured skin if working too aggressively. Using a primer such as Flexbond will strengthen your object overall. Using heat from a blow dryer or heat gun can assist in reshaping the foam to your desired overall shape if needed to avoid any unwanted tears.  

What sizes does it come in?
Lumin's Workshop Foam Clay is available in 50g, 150g, and 300g sizes.
