Two coat plaster system for medium to high suction backgrounds for wall locations comprising of 11mm Thistle HardWall (undercoat) and 3 to 6mm ThistlePro Magnetic (finish coat).

When it comes to creating a smooth and durable wall finish, the PL0053 specification offers a reliable two-coat plaster system. This system is specifically designed for medium to high suction backgrounds and includes an 11mm application of Thistle HardWall as the undercoat, followed by a finish coat of 3 to 6mm using ThistlePro Magnetic. This combination not only provides a robust underlying structure but also offers the benefits of magnetic properties, which can be particularly useful in functional spaces.

Before moving forward with the skim coat, it's essential to collaborate with the design team and the contractors on-site. This dialogue helps to ensure that everyone is aligned on the expected quality of the finish, including smoothness and flatness. Understanding design considerations is crucial, especially regarding how lighting conditions will affect the visibility of the plaster finish, which can impact the overall aesthetic appeal of the final wall surface.

For an optimal finish, specific products should be used in accordance with the standard, including Thistle GypPrime for pre-treatment and ThistlePro Magnetic for the finish coat. Always ensure that the undercoat is well-applied and completed before the finishing touches begin. Adhering to the specified materials not only boosts the quality but also maintains the structural integrity of your walls over time.

Lastly, the SpecSure® system performance warranty from British Gypsum is a reassurance that the specified systems will perform as intended throughout the building's life. This warranty necessitates compliance with all installation guidance provided by British Gypsum, so it’s vital to check with the design team before any adjustments are made to ensure that all performance requirements are still met. For more comprehensive information, visiting the British Gypsum website can provide further clarity on installation standards and product specifications.
