Two coat plaster system for medium to high suction backgrounds for ceiling locations comprising of 8mm Thistle HardWall (undercoat) and 2mm Thistle MultiFinish (finish coat).

The PL0011 specification outlines a two-coat plaster system designed for medium to high suction backgrounds, specifically suitable for ceiling applications. This system consists of an 8mm undercoat layer of Thistle HardWall, followed by a 2mm finish coat of Thistle MultiFinish. This combination ensures a robust and smooth plaster finish, perfect for achieving both aesthetic appeal and structural integrity in various settings.

Before applying the skim coat, it's crucial to communicate with the design team or on-site contractor about the expectations for finish quality, flatness, and overall design considerations. Factors such as lighting should be taken into account since they can significantly impact the perception of the plaster finish. Establishing these parameters upfront will help ensure the final appearance meets the desired standards.

The recommended products for this plastering system include Thistle GypPrime for finish coat pre-treatment, Thistle MultiFinish as the finish coat, and Thistle HardWall for the undercoat. Utilizing these specific products is essential for achieving the best results, as they are designed to work harmoniously within this plaster system.

Additionally, the SpecSure® system performance warranty from British Gypsum guarantees that the proprietary systems will function as intended throughout the building's life. It's essential to adhere strictly to the specifications and installation guidance provided by British Gypsum to maintain the warranty. Changes to the specification should not be made without consulting the design team to ensure continued compliance with performance requirements.
