Two-Componenet, Flexible Waterproofing Slurry


  • Highly flexible
  • High bonding strength
  • Easy and quick application.
  • Non-prevention of concrete inhalation and achievement of vapor permeability.
  • Crack bridging
  • Waterproofing layer under ceramic tiles, thanks to its superior adherence and flexibility features.
Product Features Surface Preparation Application Documents


  • Cement based, two-component flexible waterproofing slurry which is made of by being modified with chemical additives and polymers, is intended for use only from the positive side and ensures water and moisture insulation.


  • On horizontal and vertical areas
  • Only on the positive side,
  • Water stations, pools, water tanks and reservoirs,
  • Foundations, basement walls, terraces and garages
  • Wet areas such as kitchen, balcony and toilet

Technical Information
  • Colour: Powder component: Grey Powder Liquid component: White liquid emulsion
  • Water vapor permeability (SD): < 0,5 Class I (EN ISO 7783)
  • Capillary water absorption: ≤ 0,1 kg/m2h0,5 (TS EN 1062-3)
  • Pressurized water resistance: 7 bars (positive side)
  • Bonding strength: ≥ 1,0N/mm2
  • Crack bridging: ≥ 0,75mm
  • Depends on + 23 ± 2°C temperature and 50 ± 5% relative humidity conditions.

Surface Preparation

  • The application surface must be cleaned of oil, dust, paint, dirt, detergent etc. which prevents adhesion.
  • Surface defects must be corrected prior to the application with the use of Davco repair mortars.
  • Sharp edges and joints of construction elements must be levelled.
  • The surface must be dam


  • Pour K11 Flex liquid component in a clean container and mix it with the help of a low-speed mixer. Slowly add K11 Flex powder component in it.
  • Keep mixing until you obtain a homogenous and smooth mixture.
  • Wait for 3 minutes for the disappearance of air bubbles resulting from the mixing process.
  • Apply the mixture on the dampened and water saturated surface by using a suitable brush to obtain 0,75-1mm thickness.
  • After the first layer is allowed to be dried for about 4-6 hours, the second layer is applied perpendicularly to the first layer.
  • Total application thickness is 1,5-2 mm.
  • It must be paid attention to protect the surface against sunlight, rain and frost for not less than 3 days during and after the application.
  • Walking surfaces must be covered with ceramic tiles, glazed tile etc. 3 days after the application.
