How do I stop salt stains on the outside brickwok of our home, it only seems to be on the front of property.
There is no magic cure here. The best approach is to use a soft brush from time to time to remove the surface salts, taking care not to be brush too hard otherwise you will be pushing the salts back into the pores of the masonry.
There are salt neutralising solutions available but their effectiveness is likely to be short term and they merely mitigate the symptoms rather than treat the underlying problem.
Where salts appear on masonry, it is because there is some form of moisture movement going on. This is why it is a problem that occurs quite frequently on new build brickwork where the construction process involves a considerable amount of water, all of which has to dry out. Brick clays vary in their composition but if they contain a high degree of salts, surface efflorescence will occur from time to time whenever there is moisture movement to activate it.
