Pasty filler from Knauf

Why are ready-made fillers so popular? Quite simply because they are ready to use, do not require any mixing or maturation time and only need to be stirred briefly to be ready for use. Knauf's ready-to-use fillers have been developed for both mechanical and manual use on various surfaces.
A good example of this is Knauf Readyfix F1, a ready-to-use, air-drying spray and fine filler. It is ideal for full-surface filling or finishing of standard construction substrates such as aerated concrete, prefabricated concrete parts, in-situ concrete surfaces, plaster and gypsum boards for full-surface filling in quality Q3 and Q4. For thin-layer surfaces, Knauf Readyfix F1 can be extended to 0 to 2 mm per layer of filler; a maximum total application thickness of 3 mm can be achieved. It is generally easy to process, can be extended to zero and is very easy to sand. The consumption is around 1.80 kg/m² per mm of layer thickness. Regardless of whether Readyfix F1 is applied to concrete, plaster, plasterboard or other common substrates, high-quality surfaces are the visible result in no time.
