Salt Neutraliser, an aqueous solution based on acetic acid with a surfactant, has been specifically developed to overcome the problem of salts in mineral building surfaces and is suitable for a wide range of substrates from new plasterwork to old stone.
Due to rising dampness, salts contained in ground water are absorbed into the masonry and subsequently into the plaster coat. If the rising damp had been severe the plasterwork can loose key and visual evidence of this problem can often be noted by the presence of salt deposits. In such severe circumstances the plasterwork must be removed and re-plastering carried out in accordance with the an appropriate specification which will prevent any residual salts in the base substrate migrating into new plasterwork.
There are, however many situations where the type of salts within the masonry are such that the plasterwork remains in good condition. In these cases the Salt Neutraliser can be used thus saving considerable time and expense by not having to re-plaster these
There many other occasions where even after replastering work salt efflorescence can be seen on the new plasterwork. This often leads to concern that the damp proof course has failed when, in fact, in the majority of cases the efflorescence is due to other factors such as drying out, salts in construction, plumbing or rainwater leaks, condensation or salty bricks. Under these circumstances Salt Neutraliser is an ideal product to treat the problem.
- Neutralises the action of salts to prevent or reduce efflorescence.
- Appliable to all mineral building surfaces.
- Used as concentrate or in diluted form.
Brush away or remove all loose salts.2)
Thoroughly soak the affected area with clean tap water.3)
Apply Salt Neutraliser by brush or roller to areas showing salts contamination. Under most circumstances one coat or application will be adequate.a)
Where heavy salting on old brickwork is being treated use Salt Neutraliser as the concentrate (container strength).
On new plasterwork or light salting use Salt Neutraliser diluted with water up to 50/50 dilution rate.4)
Some frothing may occur which is due to the reaction with the salts. Allow some time for the neutralising action to be completed. A white deposit may be left on the surface where original efflorescing has taken place and is sometimes difficult to remove.5)
If re-decorating is to be applied on the treated surface the area should be washed with water and allowed to dry. Do not redecorate at any time until the treated areas are thoroughly dry.
Coverage will vary with the type of surface and substrate: 1 litre concentrate should treat 5m˛ to 10m˛.Product Data Sheets
