Knauf Hydro Flex Waterproof Liquid Film - 15 Kg

Weight: 15kg

Knauf Hydro Flex Liquid Foil Waterproof Tanking Membrane is a one-component, ready-to-use plastic liquid waterproof tanking membrane for wall and floor surfaces under ceramic tiles. The liquid foil helps protect joints and gaps between tile from allowing water through as although the tiles themselves are impermeable to water, the joints between them are not 100% waterproof. There are even micro-gaps between the tiles after perfect grouting which can allow moisture to penetrate. Allowing water to penetrate is a simple path to the growth of fungi and mould. 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.
