Hey'di Antisulphate

Designed to treat damp, salt affected masonry. Suitable for use in the treatment of above ground structures such as chimney breasts and in the treatment of flood damaged properties.

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.

Not for use on gypsum plaster or exposed brickwork. Only for use prior to the application of tanking/render. Antisulphate is not a lasting salt barrier; additional measures are required.
