weber.tec 774
Product formerly named: DEITEROL SLF
Hydrophobing treatment
weber.tec 774 is a solvent-free, transparent, hydrophobic concentrate based on siloxane micro-emulsion.
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.
Main features

- no unpleasant odour
- high penetration depth
- tack-free drying, thus no danger of contamination
- rapid formation of the roll-off effect
- high water-repellent
- for use on slightly damp substrates
- open to diffusion of water vapour
