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

When working with plastering systems, particularly for ceilings, it is crucial to understand the specifications detailing the materials and methods to be used. For a low to medium suction background, the PL0058 specification outlines a two-coat plaster system. This system employs an 8mm layer of Thistle BondingCoat as the undercoat, combined with a 2mm layer of ThistlePro FastSet Finish for the final layer. This combination provides not only a solid foundation but also a professional finish that enhances the aesthetic appeal of the ceiling.

Before the application of the skim coat, it is essential to collaborate with the design team or contractor on site. This dialogue ensures that everyone is in agreement regarding the expectations for a smooth finish, the required flatness, and how the plaster will interact with lighting. These considerations play a significant role in the success of the final appearance and can impact the overall visual quality of the space.

To achieve the best results, proper preparations are necessary. Thistle GypPrime serves as a pre-treatment for the finish coat, preparing the surface for the 2mm ThistlePro FastSet Finish, while the undercoat lays a strong base with 8mm of Thistle BondingCoat. By following these steps, the plastering work not only meets but exceeds the expected standards.

Additionally, it is important to note that the SpecSure® system performance warranty backs the materials being used. This warranty guarantees that British Gypsum's proprietary systems will perform as specified throughout the building's lifetime. Adhering to the installation guidelines provided by British Gypsum is critical to maintaining the validity of this warranty. Always consult with the design team before making changes to the specification, ensuring that these adjustments still fulfill the necessary project requirements.
