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 FastSet Finish (finish coat).

When working with plastering systems, it's essential to understand the specifications and quality requirements to achieve the desired finish. The PL0056 specification outlines a two-coat plaster system intended for use with metal lathing, particularly when bridging steel structures like columns, beams, and lintels in ceiling locations. This system consists of an 8mm layer of Thistle HardWall as the undercoat, followed by a 2mm layer of ThistlePro FastSet Finish for the smooth final touch.

Ensuring a high-quality finish is paramount, especially in spaces where lighting plays a crucial role in appearance. Before applying the skim coat, it’s advisable to collaborate with the design team or contractor on-site. Discussing the required smooth finish, flatness, and design considerations is vital for acceptance of the plaster finishes. This step helps confirm that the end result adheres to the expectations of the project and meets aesthetic standards.

The products necessary for achieving this finish include Thistle GypPrime for pre-treatment and the finishes mentioned above. Following best practices is crucial, including ensuring all materials are specified in alignment with British Gypsum’s guidelines. Notably, the SpecSure® system performance warranty guarantees the performance of these proprietary systems throughout the building's lifespan. To benefit from this warranty, it is critical to ensure that all components are correctly specified and installed according to the provided guidance.

Lastly, before making any amendments to the chosen specifications, always confirm with the design team. This ensures that any alterations will not compromise the project's performance requirements. For the most accurate information and updates, frequently checking the British Gypsum website is recommended. This collaborative approach not only enhances the final finish but also contributes to the longevity of the plastering work in the construction project.
