FIBACRYL is a ready-to-use, fiber-reinforced flexible filler for interior and exterior use. It bonds strongly to gypsum plaster, concrete, plasterboards, and primed wood painted or unpainted without spot priming. Crack- and flash-free, it’s ideal for overcoating with any filler, paint, or waterproof coating. With >0.8 MPa adhesion, high flexibility, and thickness application up to 1 cm, it delivers smooth, durable surfaces that dry in 24–48 h.
