Fine Casting Plaster is the flagship plaster from Saint-Gobain Formula. This premium-grade, off-white plaster of Paris is sourced and calcined entirely in England, making it the industry standard for fibrous plasterwork, such as decorative cornices and ceiling roses. Beyond its performance, it offers significant environmental benefits. Because all Formula plasters are manufactured in Britain and are transported directly to us, they boast a low carbon footprint. Furthermore, Fine Casting Plaster is fully recyclable; as a pure gypsum product, it can be reprocessed indefinitely for applications like plasterboard manufacturing without any loss in quality.
