The polymer film created by the RDP powder allows the compound to move and flex with the substrate, reducing the risk of cracking or failure. This is particularly beneficial in areas where the substrate may be subject to temperature fluctuations or movement, such as outdoor patios or areas with underfloor heating. The increased flexibility provided by RDP powder ensures that the self-leveling compound will maintain its integrity over time.
Lastly, RDP powder can also contribute to the sustainability of self-leveling compounds. The polymer used in RDP powder is typically derived from renewable sources, making it an environmentally friendly choice. Additionally, the improved workability and durability of self-leveling compounds containing RDP powder can result in reduced material waste and the need for future repairs or replacements. This not only benefits the environment but also helps to reduce costs for contractors and end-users.
In conclusion, the use of RDP powder in self-leveling compounds offers numerous benefits. From improved workability and adhesion to increased durability and flexibility, RDP powder enhances the performance and longevity of self-leveling compounds. Additionally, its sustainability credentials make it an attractive choice for environmentally conscious contractors and end-users. By incorporating RDP powder into their self-leveling compounds, construction professionals can ensure the creation of smooth, level, and long-lasting surfaces.
