Uniacryl 400 is a one-component sealing putty based on a fungicidal polyacrylic dispersion, which offers high elasticity and great weather-resistance. Undoubtedly, it can be defined as the best representative of the acrylic family since its great technical properties allow for a wide range of applications.
Uniacryl 400 is especially recommended for joints in prefabricated buildings (blocks, warehouses, etc), accommodating movements and deformations up to 18% of the original joint width; for waterproof sealing between various materials, for building joints (concrete, plaster, brickwork, cement, wood) and for construction parts such as window frames, window sills etc. Not recommended for joints in continuous contact with water.
Uniacryl 400 can be painted with almost any kind of paint. Tests should be carried out before.
