Roman Stucco Cast
Roman Stucco Cast is a traditional fast setting mortar for mouldings cast on the bench. Made with traditional Roman Cement, our 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 into moulds to make realistic coping stones and man made rock features.
Becasue we make our Roman Stucco from burnt limestone and mineral sands, not resins and acrylics, you can achieve the subtle patinas and matt finishes for the 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.Find Supplier

Pour into a mould prepared with mould release oil, using vibration to remove air bubbles. On large pieces work green on green, do not pour more product on to a dried and set surface. Leave to set before demoulding. Initial set is temperature dependent, but normally within 15 to 20 minutes. De-moulding times vary depending on the shape and complexity of the mould.
