Hyper Fill - Kerakoll France

Hyper Fill is a paintable, acrylic-based sealant intended for filling cracks and gaps in building substrates. It is formulated for sealing connection joints between masonry or plaster/render and door or window frames before varnishing, and for the localized repair of surface cracks. The product is soft to extrude, provides a smooth surface finish, and cures rapidly. Its formulation ensures stability under UV exposure, allowing use in both internal and external applications where a paintable, deformable sealant is required.
