The damaging effects of soluble salts are intimately linked with wetting and drying cycles at the masonry face.
Effects of soluble salts on coating life general effects soluble salts can affect the ability of coatings to protect steel in several ways. Salts that remain on the substrate can result in blistering of the coating. This phenomenon, known as os-motic blistering, can produce pressures of several thousand psi, which is enough to cause the coating.
High soluble salt levels can reduce the growth of most crops.
Dissolved salt solutions can accelerate the oxidation of steel, resulting in undercutting of the coating. Although corrosion can occur in the absence of any salts due to crevice corrosion, oxygen concentration cells or general corrosion, the presence of soluble salts increases the corrosion rate.
