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 Thistle MultiFinish (finish coat).

When working with plaster systems, particularly the PL0016 specification, it's essential to understand the layers involved and their specific use cases. This system is designed for situations where metal lathing is employed, which is common when bridging steel columns, beams, and lintels in wall construction. The PL0016 involves applying an 11mm layer of Thistle HardWall as the undercoat, followed by a final 2mm layer of Thistle MultiFinish to achieve that smooth, high-quality finish that is often desired in modern interiors.

Before you begin layering the plaster, it's vital to consult with the design team or contractors present at the site. This collaboration is crucial to align on the desired quality of the finish, including aspects of smoothness and flatness. Additionally, considering how the plaster will interact with lighting is essential; good communication here ensures that the final aesthetics meet the project's vision and requirements.

The products specified for this system are quite straightforward. For the finish coat, begin with Thistle GypPrime as a pre-treatment to create an ideal base for the 2mm layer of Thistle MultiFinish. This method not only enhances adhesion but also contributes to the overall performance of the finish. The underlying 11mm Thistle HardWall layer is equally important, providing the necessary support and leveling for the final surface.

One of the key aspects to keep in mind is the SpecSure® system performance warranty provided by British Gypsum. This warranty assures that their proprietary systems will deliver the specified performance throughout the building's lifetime. However, to benefit from this warranty, all components must be specified accurately and the installation must adhere to British Gypsum’s guidance. Always seek confirmation from the design team when considering changes to your specifications, ensuring that all solutions comply with project requirements.
