NEOKRYLL is a transparent, acrylic fixative for exteriors. Its special formula, consisting of special acrylic resins with very fine particles, makes it highly pervasive (up to 5 mm) and allows an efficient consolidation and sealing of the substrate. It is especially recommended for highly absorbent walls, chalking substrates, old crumbly plasters, plaster screeds, mineral substrates, fibre cement and in general for all kinds of wall substrates. It has a low odour level, is non inflammable and is friendly to both humans and the environment.
