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

When it comes to plastering, achieving a high-quality finish is crucial, especially in ceiling locations that require a two-coat plaster system. The PL0010 specification outlines a dependable method for preparing medium to high suction backgrounds. This system consists of an 8mm undercoat of Thistle HardWall, followed by a 2mm finish coat of ThistlePro DuraFinish. This combination not only enhances durability but also ensures a smooth, aesthetically pleasing surface suitable for various design schemes.

Before applying the skim coat, it's important to collaborate with the design team or contractor on site. This step helps determine the desired quality of the smooth finish, the required flatness, and other design considerations, particularly in relation to how the plaster will respond to lighting conditions. Attention to these details can significantly improve the final appearance and functionality of the finished surfaces.

To ensure the best results, specific products retain paramount importance. Start with a pre-treatment using Thistle GypPrime, followed by the undercoat application of Thistle HardWall at 8mm thick. Finally, finish off with the 2mm coat of ThistlePro DuraFinish. Each product has been designed to complement one another, making adherence to these specifications key for a successful plastering project.

It's also essential to understand the warranty implications within the SpecSure® system. This warranty assures that British Gypsum proprietary systems will meet performance specifications for the entire lifetime of the building, provided that all components are accurately specified and installed according to the guidelines. Always confirm with the design team before making any modifications to the established specification, ensuring it still aligns with the project’s requirements and performance goals for a flawless finish.
