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

When it comes to plastering walls, particularly in settings with medium to high suction backgrounds, using a robust two-coat plaster system is essential for achieving optimal results. Specification PL0029 outlines a highly effective method utilizing 11mm of Thistle DriCoat as the undercoat, paired with a 2mm Thistle BoardFinish for the finishing coat. This combination not only improves durability but also enhances the aesthetic appeal of the walls.

Before applying the skim coat, it's crucial to engage with the design team or contractor on-site. This collaboration ensures that everyone is on the same page regarding the quality of the smooth finish, the required flatness, and any specific design considerations. Discussing these aspects upfront allows for a seamless process and helps achieve the desired visual effects, particularly under varying lighting conditions.

The SpecSure® system performance warranty from British Gypsum is another key element to keep in mind. This warranty assures that the proprietary systems will maintain their performance throughout the building's lifespan, but it requires strict adherence to the installation guidelines. To safeguard this warranty, it’s vital to use all specified components and consult with the design team before making any changes to the original plans. Such diligence ensures that the plastering work meets the necessary project specifications and performance standards.
