Neutralise salts 

PermaSEAL Salt Neutraliser is an aqueous solution that has been specifically developed to deal with the problem of salts in mineral building surfaces.

Getting Rid of Salts

In some circumstances salt deposits are visible on the surface of plasterwork. These salts can come from within the wall substrate. The background substrate made up of bricks, mortar beds and renders can often contain salts. These can then pass through into the internal plaster finishing coat. This can be caused by damp or even just the re-plastering of a wall.

Often in this case the plaster finish remains in good condition but has a white fur-like deposit on the surface that can cause paintwork to de-bond. In this instance, PermaSEAL Salt Neutraliser can be used to neutralise the salts in the sound plaster finish. This saves you considerable time and expense by removing the salts without having to re-plaster these areas.

If rising damp has been diagnosed as the cause of the salt deposits, the whole plaster finish must be removed along with the background render back to the original masonry. Once the rising damp has been treated, re-plastering then needs to be carried out in accordance with the appropriate specification (see Permaproof Waterproofer) to prevent any residual salts in the structural masonry migrating into new plaster finishes.

Sometimes, even after re-plastering, salt efflorescence can be seen on the new plaster finish. In the majority of cases, the efflorescence is due to other factors such as drying out, plumbing leaks, rainwater leaks, salts in construction materials or salty bricks rather than a failed damp proof cause. Salt Neutraliser is an ideal product to clean the efflorescence from the brick and treat the problem.

How Salt Neutraliser Works

Salt Neutraliser is a water-based formulation designed to penetrate into the surface. It immediately reacts with the salts in and on the substrate, neutralising them. It also creates an insoluble barrier against further salt movement into the surface.

How to apply PermaSEAL Salt Neutraliser

  1. Brush away or remove all loose salts, cleaning the efflorescence from the affected surfaces
  2. Thoroughly soak the affected area with clean tap water
  3. Apply Salt Neutraliser by brush or roller to areas showing salts contamination 

Note: Some frothing may occur – this is due to the reaction of Salt Neutraliser with the salts. You should allow some time for the product to neutralise the salt and the neutralising action to be completed. A white deposit may be left on the surface where original efflorescence has taken place and this can be difficult to remove.

   4. If you want to re-decorate the treated surface, you should wash the area with water and allow to dry. Do not re-decorate until all treated areas are thoroughly dry. 

Coverage 

This will vary with the type of surface and substrate: 1 litre of concentrate should treat 5 to 10 m².
