The Knauf Perlfix is a gypsum-based mounting adhesive designed for interior work, specifically for gluing gypsum boards and thermoplastic panels to walls. This dry mortar is formulated with special adhesion additives to ensure a secure bond between the boards and the substrate. It comes in a 30 kg bag and should be stored in a cool, dry space to maintain its quality throughout its nine-month shelf life. When applying the adhesive, you can use the dollop method by placing rows of approximately 100 mm diameter spots on the surface. Depending on the material, consumption typically ranges between 3.5 and 5 kg per square meter for boards, while wall-ceiling joints require about 1 kg per square meter. This makes it a practical choice for builders and renovators looking for a reliable way to install drywall systems.
