The widespread use of gypsum cornices is largely attributed to their pristine white tone, which blends seamlessly with a variety of wall styles-this also explains why the majority of gypsum cornices on the market remain in their original white shade. However, the key to their moisture resistance lies not in surface paint, but in the production process.
The core technique involves a layered casting method: an exceptionally fine, high-density gypsum slurry is applied to the outermost layer of the mold, while standard gypsum slurry is used for the inner structure. This approach creates a dense, smooth surface layer that effectively blocks moisture absorption. Not only does this enhance the product's durability, but it also improves its aesthetic appeal, contributing to a more refined finish.
This simple yet intelligent manufacturing adjustment delivers multiple benefits-proving that sometimes, a small innovation in process can achieve both functional and visual improvements, offering lasting value in practical applications.
