Gypsum and Plaster

These USG products will meet your casting or mold-making gypsum and plaster needs. They are the industry standard for figurines, plaques, and lamp bases and are noted for outstanding performance and long life. For high-quality novelty and statuary castings that require extremely hard surfaces, or for general purpose applications requiring a soft plaster, “plaster of Paris”, you can find it here. We also have super-strength gypsum cement, offering the lowest expansion of any rapid-setting gypsum cement.
