Knauf Hydro Flex Liquid Foil Waterproof Tanking Membrane - 15 Kg
Weight: 15kg
Knauf Hydro Flex Liquid Foil Waterproof Tanking Membrane is a one-component, ready-to-use highly plastic liquid waterproof tanking membrane for wall and floor surfaces under ceramic tiles. Although the tiles themselves are impermeable to water, the joints between them are not 100% waterproof. Even with very precise grouting, there are micro-gaps between the tiles through which moisture can penetrate. This is a simple path to the growth of fungi and mold. To avoid this, it is best to insulate the surface under the tiles with Knauf Hydro Flex liquid foil. The foil creates a waterproof layer that acts as a barrier to moisture and prevents it from penetrating the substrate.
CHARACTERISTICS

INSTALLATION
- The substrate must be dry, clean and dust-free,

- Prime the substrate; dilute the Hydro Flex in a ratio 1:4 with water, prime the wet zones with a brush or roller,
- Let the primed surface to dry for 3 hours,
- Fix sealing tapes to wall-floor joints,
- Tape overlap must be at least 2 cm,
