Plaster is a construction material used for protecting, coating, and decorating interior ceilings and walls. It is also useful for architectural mouldings like cornices, ceiling roses, and corbels. The most common plaster forms are lime, cement, or gypsum mixed with sand and water. We offer many plaster products to help make your interior walls right. Our British Gypsum thistle multi finish product choice provides excellent long-term value. We also offer competitive pricing for other choices like thistle multi-board and thistle hardware. Our bulk plaster bag is also the perfect choice for larger interior projects.
