A solvent free, low-viscosity watery fluid solution for mineralization of salts that damage the building structure.

How it works:

Employs a neutralising process which prevents salts being transferred into the tanking slurry.


Brush or spray apply to a ratio of 50% Heyen Antisulphate to 50% Water as the first coat. 24 hours later re-apply using Anti-sulphate as a concentrated formulation.
