Description
British Gypsum Thistle Hardwall, a quick-drying undercoat plaster, formulated for medium to high suction masonry backgrounds including bricks, aircrete blocks, and medium-density blockwork.
It can be applied by hand or with a mechanical plastering machine, offering flexibility on site and supporting faster application where required.
Once set, it provides a durable, high-impact undercoat that is ideal for finishing with British Gypsum Thistle plasters.
It also offers higher-than-normal resistance to efflorescence, reducing the risk of salt deposits forming on the surface. Its robust formulation delivers a strong base coat with excellent adhesion and long-term reliability.
We provide a next working day delivery service on most orders placed before 4:00pm (Monday to Friday), delivered straight to your site, home or office. Orders placed after 4:00pm or over the weekend will be dispatched the next working day.
