SikaTop 582 Seal

SikaTop®-582 Seal is a two-component flexible waterproofing coating based on cement and acrylic, suitable for both negative and positive side applications. It provides long-lasting protection on concrete surfaces with its high adhesion strength and capillary action. In addition to water resistance, it creates an effective barrier against carbonation and the harmful effects of de-icing salts.

Application Areas

  • Vertical and horizontal surfaces, indoor and outdoor applications
  • Wet areas such as bathrooms, kitchens, and balconies
  • Waterproofing of retaining walls
  • Water tanks and tunnels
  • Elevator shafts
  • Reinforced concrete pipes
  • All areas requiring protection of concrete against water, carbonation, and de-icing salts

  • Resistant to both negative and positive water pressure
  • Provides deep protection through capillary action
  • Easy application with extended working time
  • Long-lasting performance with a non-shrinking and crack-resistant structure
  • Allows water vapor permeability, enabling the structure to breathe
  • Bonds strongly with the surface due to high adhesion strength
  • Easy application by brush or spraying machine
  • Resistant to freeze-thaw cycles
