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

The PL0030 specification outlines a two-coat plaster system ideally designed for medium to high suction backgrounds in wall applications. This system comprises an 11mm layer of Thistle HardWall as the undercoat, paired with a 2mm finish of ThistlePro DuraFinish. This combination ensures durability while providing a high-quality surface ready for painting or further finishes. Using these specific products helps to achieve optimal adhesion and surface smoothness, critical for both aesthetic and performance standards in construction projects.

To ensure a flawless plaster application, it's essential to communicate with the design team or contractor on-site prior to applying the skim coat. Discussing requirements for smoothness, flatness, and how the plaster will interact with light will aid in achieving the desired finish. Every project may have unique lighting and aesthetic considerations, making it crucial to align expectations with the design specifications before proceeding.

In terms of preparation, the application process begins with a pre-treatment using Thistle GypPrime, which enhances the adhesion of the finish coat. Afterward, the top layer consists of 2mm of ThistlePro DuraFinish, applied smoothly over the undercoat of 11mm Thistle HardWall. Following this method ensures that both the texture and durability of the wall meet design and structural standards.

Moreover, it is important to adhere to the SpecSure® performance warranty provided by British Gypsum. This warranty guarantees that the system will perform as intended for the life of the building, but it mandates strict adherence to installation guidelines. Any deviations from specified materials or methods can void warranty coverage. Always collaborate with the design team before implementing changes to ensure that any alternatives still achieve the required performance metrics for the project.
