weber.tec 774

Composition

Concentrated micro-emulsion of silane/siloxane resins

Fields of application

Used for the hydrophobic treatment of absorbent mineral building materials, like sand- lime stones, brickwork, natural stones, clinkers and mineral paints as efficient protection against moisture (driving rain) on vertical and heavily inclined surfaces. Also for increasing their resistance to frost and de-icing salts. For non-pedestrian and non-vehicular traffic surfaces. Furthermore, suitable for Etics thermal composite systems with polystyrene rigid foam panels.
