The Dekguard Elastic system comprises a single component penetrating primer and a single component elastomeric pigmented coating. It is used to protect atmospherically exposed reinforced concrete structures from attack by acid gases, chloride ions, sulfates, oxygen and water, especially where there is a danger of subsequent cracks appearing within the substrate. Dekguard Elastic is suitable for use on all types of structures, including those in coastal environments. It is equally suitable to for new and existing structures.

Features/ Benefits:

  • Can accommodate substrate cracking up to 6 mm and cyclic movement of 1 mm.
  • True elastomeric coating with excellent elongation and recovery properties which are maintained at sub-zero temperatures.
  • Excellent barrier to carbon dioxide, chloride ions, oxygen and water.
  • Allows water vapour to escape from structure.
  • UV-resistant with high resistance to the effects of long-term weathering.
  • Water-based.
  • Wide range of decorative colours.
