Experience the versatility of the British Gypsum Thistle Bonding Coat Plaster 25kg 4 Pack, a multi-purpose undercoat plaster tailored for smooth or low-suction backgrounds, including dense blockwork, concrete, tiling, plasterboard, and surfaces pre-treated with Thistle Bond-it. This pre-mixed gypsum plaster, incorporating exfoliated vermiculite aggregate, simplifies on-site preparation with the addition of just clean water. Its fine and lightweight composition ensures excellent workability, allowing for reliable performance in spreading, ruling, or darbying. The end result is a robust, level undercoat that serves as a durable foundation for finishing plasters, creating a surface primed for decoration. It can be applied directly to plasterboard when dubbing out is necessary, or it can effectively restore and level existing internal walls and ceilings in refurbishment projects.
