Wykamol Salt Neutralizer, 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 Wykamol Re-plastering Specification or other appropriate specifications 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 areas.
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.
