British Gypsum Thistle Bonding Coat — the undercoat that grips where others slide.
A gypsum undercoat plaster designed for low to medium suction backgrounds and smooth surfaces: concrete, dense block, engineering brick and similar walls where a standard browning would struggle to key.
- Applications: Undercoat on smooth or low-suction walls, patch repairs, and preparation before a Thistle finish coat.
- Recommended thickness: 11mm on block, 11mm on smooth concrete.
- Suitable backgrounds: Low to medium suction and smooth backgrounds.
- Bag size: 25kg.
Finish with Thistle Multi Finish Plaster for a smooth top coat, or see Thistle Hardwall Plaster if your background has higher suction.
