British Gypsum Thistle Hardwall Plaster 25kg
The British Gypsum Thistle Hardwall Plaster is a high-performance undercoat plaster designed for strength, durability, and impact resistance. It’s ideal for use on most masonry backgrounds including aircrete blocks, common bricks, medium-density blocks, and dense blocks. However, it’s not recommended for use on smooth, low-suction surfaces.
This versatile plaster can be applied either by hand or with a mechanical spray plastering machine, making it suitable for both traditional and modern application methods. It provides an excellent base for finishing coats while offering superior hardness and impact resistance, making it perfect for areas exposed to high levels of wear and tear such as hallways, corridors, and busy commercial environments.
