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

When working with plaster systems, the PL0054 specification outlines a two-coat plaster system ideal for medium to high suction backgrounds, particularly suited for ceilings. This system consists of an 8mm layer of Thistle HardWall as the undercoat, followed by a 2mm layer of ThistlePro FastSet Finish for the top coat. This combination not only ensures durability but also provides a smooth aesthetic finish, making it an excellent choice for various interior applications.

Before applying the final skim coat, it's essential to collaborate with the design team or contractor on-site. Confirming the desired quality of the smooth finish, assessing the flatness, and understanding design considerations related to lighting are vital steps. These discussions help establish acceptance criteria for the smooth plaster finishes and ensure that the finished product aligns with the project’s visual and functional requirements.

The choice of products in this system is critical for achieving the desired results. The process begins with a pre-treatment of Thistle GypPrime, followed by the application of the ThistlePro FastSet Finish as the finishing coat, and finally, the Thistle HardWall serves as an undercoat. Each layer plays a specific role in enhancing the overall performance and finish quality, which is why selecting the right components is paramount for any successful plastering project.

It's important to highlight that the SpecSure® system performance warranty guarantees that British Gypsum's proprietary systems will perform as specified throughout the building's life. Adhering to the installation guidance and ensuring all components are fully specified is crucial. Additionally, any changes to the initial specifications should be discussed with the design team to validate that the chosen solutions meet the necessary project performance standards. For more comprehensive information, consulting the British Gypsum website is recommended.
