High Specification Salt Inhibitor

High Specification Salt Inhibitor - No Hydro 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

Effective Rising Damp Treatment - No Hydro Damp Proof Cream DPC 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.

Coverage Calculator


  1. To create the gauging solution, mix 1 part No Hydro Salt Inhibitor with 24 parts water. All water should be fresh, clean and free from oil or other organic contaminants.
  2. First Coat: Prepare 3 parts sand and 1 part cement using the dilute No Hydro Salt Inhibitor solution prepared above. The sand should be specified as washed, sharp sand, loam free which satisfies British Standard BS882:1992 β€œM” Grading.
  3. Use the minimum No Hydro Salt Inhibitor gauging solution to ensure a dense coat. As a guide, no more than 8 litres should be used for every 50 kg of dry mix. Compact the resulting mix well into raked out joints, and render to give an overall thickness of 12 mm. Do not over-trowel. When the cement achieves a first set, then scratch to form a key.
  4. Second Coat: the mix is as for the first coat except that water is used instead of No Hydro Salt Inhibitor solution. This is applied as a further 12 mm coat, giving a total thickness of 24 mm for both coats. This coat should be applied before the first coat has finally set in order to obtain a satisfactory adhesion between the two coats. Scratch the surface to form a key. Do not over-trowel.
  5. Finishing Coat: This should consist of a 3 mm layer of gypsum skim finish or similar finish. Other finishes are acceptable provided that they are porous. Do not polish.
  6. No decoration should take place for at least 6 weeks after treatment (or until the wall has dried out).
  7. After this time we recommend the use of a mould-resistant emulsion paint. We do not recommend the use of wall paper or high build paints such as enamels.

    Used this when replastering after DPC Installation in the new render to prevent salt contamination from the treated walls, the walls are perfect with no damp or salt contamination problems.
