Two coat plaster system for use with metal lathing when bridging steel columns, beams and lintels for ceiling locations comprising of 8mm Thistle HardWall (undercoat) and 2mm ThistlePro DuraFinish (finish coat).

When it comes to installing a two-coat plaster system, understanding the specifications and requirements is crucial. The system specified here, PL0001, is designed for use with metal lathing, particularly when bridging structural elements like steel columns, beams, and lintels in ceiling applications. It consists of an undercoat of 8mm Thistle HardWall followed by a finish coat of 2mm ThistlePro DuraFinish. This combination not only provides a robust surface but also ensures a smooth, quality finish that can stand the test of time.

Before applying the skim coat, it's essential to collaborate with the design team or contractor on-site. Discussing matters such as the desired quality of the smooth finish, overall flatness, and any design considerations is vital for achieving a satisfactory result. Lighting can significantly impact the perception of plaster finishes, so these discussions can help clarify expectations and ensure the finished appearance aligns with the project's goals.

Several products are key to this plastering system. The pre-treatment for the finish coat utilizes Thistle GypPrime, followed by the application of the specified 2mm of ThistlePro DuraFinish. The foundation of this system is provided by the 8mm undercoat of Thistle HardWall, which serves to create a sturdy base for the finish coat. Each component plays a distinct role in ensuring the durability and aesthetics of the plastering work.

Additionally, adherence to the SpecSure® system performance warranty is crucial. This warranty assures that all components of the British Gypsum proprietary systems will perform as specified throughout the lifespan of the building. It's important to ensure that all products are used as prescribed in their respective installation guides. Before making any alterations to the specification, always confer with the design team and obtain appropriate substantiation to confirm that the proposed modifications will still meet all necessary project performance criteria.
