No Hydro Salt Inhibitor

High Specification Salt Inhibitor

No Hydro Salt Inhibitor is a high specification plaster additive recommended following the installation of a remedial DPC correct re- plastering. Even though a DPC is effective, hygroscopic salts introduced by rising damp may cause moisture to be attracted to the wall.

When a new damp-proof course has been installed it will normally be necessary to hack of salt contaminated plaster and to replaster using a salt-resistant render. Such a render can be formed by using a mixture of sharp sand and cement guaged with diluted No Hydro Salt Inhibitor.

Rising Damp

Rising damp is when groundwater rises up load-bearing walls in capillary action through the fine capillaries and pores of brick and mortar in a wick effect in walls that have no original DPC installed during the construction of a property.

The groundwater rising contains ground salts which are nitrates and chlorides. It is these ground salts that cause the contaminated plaster. These ground salts are hygroscopic and naturally absorb and hold moisture causing the walls to become highly saturated, contaminating plaster, and causing the skirting boards to decay and rot as they are against damp walls.
