We stock high-quality plaster from trusted brands like Thistle, all available in bulk 25kg bags for convenience on-site. Options include Hardwall for added impact resistance, Bonding Coat for preparing smooth finishes, and MultiFinish for a versatile all-in-one solution that works on everything from blockwork to plasterboard, even painted or tiled surfaces.

Made to British Gypsum’s standards, these plasters are known for their strength, ease of use, and minimal waste, ideal for professionals who need materials they can trust to perform under pressure.

You can buy plaster online through our website with fast delivery options available, including same-day and next-day service depending on your location. Prefer to browse in person?
