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 dampened and saturated with water prior to the application.


  • Pour K11 Ultra Flex liquid component in a clean container and mix it with the help of a low-speed mixer. Slowly add K11 Ultra Flex powder component in it.
  • Keep mixing until you obtain a homogenous and smooth mixture.
  • No additional water required.
  • Wait for 5 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 2-3 hours, the second layer is applied perpendicularly to the first layer.
  • If the application is to be performed with the help of a spud, wavy and irregular surfaces must be flattened prior to the application.
  • It must be paid attention to protect the surface against sunlight, rain and frost for not less than 2 days during and after the application.
  • The surfaces which are open to foot traffic must be covered with ceramic or glazed tile etc. 2 days after the application.
