Two coat plaster system for use with metal lathing when bridging steel columns, beams and lintels for wall locations comprising of 11mm Thistle HardWall (undercoat) and 2mm ThistlePro PureFinish (finish coat).

The PL0041 specification outlines a two coat plaster system designed specifically for metal lathing applications, particularly useful when bridging structural elements such as steel columns, beams, and lintels in wall locations. The system consists of an 11mm undercoat using Thistle HardWall, followed by a 2mm finish coat with ThistlePro PureFinish. This combination not only provides structural support but also ensures a smooth, aesthetically pleasing surface for various applications.

To achieve a high-quality finish, it's essential to collaborate with the design team or contractor prior to the application of the skim coat. Discussing aspects such as the quality of finish, flatness, and various design considerations will help ensure that the plaster meets the acceptance criteria, especially under specific lighting conditions. Proper attention to these details can significantly enhance the overall appearance and performance of the plaster work.

The recommended products for this system include a pre-treatment of Thistle GypPrime, along with the aforementioned finish and undercoat materials. Utilizing these specific products ensures compatibility and optimal performance, making it easier to achieve the desired results in your plastering projects.

Moreover, the SpecSure® system performance warranty provides assurance that all components will perform as intended throughout the building's life. To protect this warranty, all materials must be specified and installed according to British Gypsum's guidelines. Always consult the design team before making modifications to ensure that the assembly remains compliant and effective for the project’s specifications. For further details, refer to the British Gypsum website for comprehensive installation guidance and warranty information.
