Surface Preparation

  • Any protrusions or matters which may damage the product must be removed
  • All surfaces must be cleared of dirt, dust, oil, curing components and any residuals.
  • All gaps, cracks and edges are repaired with Lanko 731 or other suitable repair materials.

Application

  • Pour K11 Flex Rapidex liquid product in a clean mixing container.
  • Slowly add K11 Flex Rapidex powder component while mixing to ensure full plastic stability.
  • The mixture must be stirred for 2-3 minutes to ensure proper distribution of the components.
  • Dampen the surface with water beforehand.
  • Do not allow water accumulation. Very porous surfaces must be primed with Lanko 160 prior to the application of K11 Flex Rapidex.
  • Apply the mixed material to the prepared surface with the help of a brush or roll.
  • Apply two coats depending on the conditions available at the area and required film thicknesses. In case of using a spud for the application, all wavy or irregular surfaces must be repaired prior to the application of K11 Flex Rapidex.
  • In this way thickening of the material prior to the application will be prevented.
  • The 1st coat must be ventilated for about 1-1,5 hours before the application of the 2nd coat.
  • Actual drying period will vary by the applied thickness, roughness of the surface and ambient temperature.
  • The surface subjected to the application of K11 Flex Rapidex must be protected.
