Balsa Foam is the amazing plastic foam that carves like butter and paints like wood. It's ideal for sculpting and model making because it can be carved, chiseled, sawed, textured, or embossed with sharp-edged detail.
Like balsa wood, it accepts virtually any kind of spray or brush-applied paint. Use a water-based finishing medium to seal the foam and harden the surface. Unlike other plastic foams, Balsa Foam does not expand, contract, or warp at temperatures below 350°F (177°C).
Balsa Foam II is the same as Balsa Foam, but with 10 lb (per cubic foot) density. This higher density results in a more durable model, yet Balsa Foam II is still easy to carve and shape. It's great for 3-dimensional model making.
