  • For use in the treatment of above ground structures such as chimney breasts and in the treatment of flood damaged properties to treat damp, salt affected masonry.
  • Only for use prior to the application of tanking and render.
  • Not for use on gypsum plaster or exposed brickwork.


Hey'di Antisulphate is a deep penetrating liquid that renders soluble salts in salt-affected masonry insoluble, thereby preventing the passage of hygroscopic salts from the substrate into any new mineral coating that is applied such as Hey'di K11 tanking or cement render. Coverage depends on application; see manufacturers technical datasheet.

Antisulphate is not a lasting salt barrier; additional measures are required.

Features and benefits:

  • Essential element of the Hey’di K11 basement tanking system.
  • Used in flood damaged properties.
  • Prevent the movement of hygroscopic salts.
