Roman Stucco Cast

Roman Stucco Cast is a traditional fast setting mortar for mouldings cast on the bench. Made with traditional Roman Cement, Lime Green's casting mortar has great durability while weathering with a natural stone-like appearance. It can be used to create many masonry features, repair steps and sills or cast embellishments. You can pour Roman Stucco Cast into moulds to make realistic coping stones and man-made rock features.

At Lime Green, we make our own Roman Stucco from burnt limestone and mineral sands, not resins and acrylics, you can achieve the subtle patinas and matt finishes for a natural look. Roman Stucco Cast is poured into a mould where it will quickly set without shrinking, recreating fine details and ornate 3-dimensional shapes. And because it is made from stone, it ages and weathers like stone. Enabling you to repair work with like for like detail.
