Two coat plaster system for medium to high suction backgrounds for wall locations comprising of 11mm Thistle HardWall (undercoat) and 2mm ThistlePro FastSet Finish (finish coat).

The specified plastering system, designated as PL0057, employs a two-coat approach designed for medium to high suction backgrounds, making it ideal for various wall surfaces. The undercoat consists of 11mm Thistle HardWall, which provides a solid foundation, while the finish coat utilizes 2mm ThistlePro FastSet Finish, known for its quick-drying properties and smooth finish. This combination ensures a robust and aesthetically pleasing surface that is ready for the final touches in no time.

Achieving a premium finish requires close collaboration with the design team or contractor on-site. It's essential to discuss expectations regarding the smoothness, flatness, and overall design considerations before applying the skim coat. Important aspects such as lighting can greatly influence the perceived quality of the finished surface, so establishing clear criteria for acceptance will help ensure that the final plaster meets or exceeds all intended specifications.

When preparing for the plaster application, specific products play crucial roles. Thistle GypPrime is used for pre-treating the finish coat, allowing for optimal adhesion. Following this, the two primary components of the system include the 2mm ThistlePro FastSet Finish for the top layer and the 11mm Thistle HardWall for the undercoat. Each of these products is tailored to work seamlessly together, guaranteeing an effective and long-lasting result.

It’s important to note the additional requirements outlined by British Gypsum's SpecSure® system performance warranty. This warranty ensures that the proprietary systems will meet specified performance standards throughout the building's lifetime, provided all components are correctly used according to the installation guidance. As changes to the specification may impact performance, it's essential to consult with the design team and seek approval for any alterations, ensuring that project goals are consistently met.
