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

When it comes to achieving a smooth and high-quality finish for ceiling locations, the two-coat plaster system specified as PL0038 is an excellent choice. This system comprises an 8mm layer of Thistle BondingCoat as the undercoat and a 2mm layer of ThistlePro PureFinish for the final finish. This combination is particularly effective on low to medium suction backgrounds, ensuring durability and a professional appearance.

Before applying the skim coat, it is essential to coordinate with the design team or contractor on-site. Discussing the desired quality of finish, including smoothness, flatness, and how these factors will interact with lighting, is crucial. This collaboration can help ensure that the finished plaster meets not only aesthetic expectations but also functional performance criteria.

For optimal results, prepare the finish coat using Thistle GypPrime as a pre-treatment to enhance adhesion. This step is essential to achieving the best results with the ThistlePro PureFinish. Remember that the correct application of the Thistle BondingCoat undercoat also plays a significant role in the overall success of the project.

Lastly, it’s important to be aware of the SpecSure® system performance warranty from British Gypsum. It guarantees that the specified systems will perform reliably throughout the building's lifetime, provided that all installation guidelines are met. Before making any changes to the specification, always consult with the design team to ensure alignment with project requirements and to maintain the integrity of the build.
