Mortero fibra impermeabilizante

Knauf Waterproofing Fiber Mortar is a flexible, single-component, fiber-reinforced cementitious mortar designed to seal and waterproof surfaces before installing ceramic tiles, slabs, or natural stone.

It is suitable for walls and floors in areas exposed to water and moisture, such as bathrooms, showers, kitchens, patios, and balconies. It can be used both indoors and outdoors, as it is resistant to water, freezing temperatures, and temperature fluctuations.

Its fiber reinforcement helps bridge small cracks and provides greater protection against subsequent movement of the substrate. It has a high capacity to prevent water from penetrating concrete or masonry and offers good adhesion without the need for a primer on suitable substrates.

It is supplied as a powder, mixed only with water, and can be applied with a trowel or brush, depending on the consistency of the mixture.
