Aguaplast Fibra

Aguaplast Fibra is a ready-to-use putty specifically designed for sealing and reinforcing dynamic cracks and fissures—that is, those subject to slight movements that can cause a conventional repair to reopen. It contains reinforcing fibers and can be used both indoors and outdoors on substrates such as concrete, cement, plaster, acrylic paints, or wood.

It’s particularly useful when a crack requires more than just filling: the putty itself helps reinforce the repair, and Beissier even suggests it as a replacement for certain elastic strips. It can be applied in layers up to approximately 3 mm thick, with drying times depending on the thickness and environmental conditions. Compared to Aguaplast Rellenos, its main advantage is not filling large voids, but rather providing a better solution for cracks that are subject to movement.
