Fermacell Joint Filler

Fermacell Joint Filler is available in 5kg or 20kg bags, offering flexibility to suit your specific project needs. This synthetic-resin modified, gypsum-based filler is designed for the manual filling of joints, with or without joint tape.

Its advanced formulation enables the creation of joints with exceptional tensile strength, making it ideal for connecting square-edged boards and filling the 5-7mm gap between them.

Once applied, Fermacell Joint Filler can be easily sanded to achieve a smooth, flawless surface, ready for decoration. It is also suitable for use on walls with a 250mm screw fixing and has low emissions, ensuring a cleaner, healthier working environment.
