Iron sulphate is used in ochre wood paint as a fungicide and mordant. It helps to expand the pores of the wood to allow the oil to penetrate and also helps to create a slight saponification of the oil so that it can be diluted with water. The ochre or flour paint then becomes an oil-based paint that can be diluted with water. This type of paint is particularly recommended for wooden frames (doors, windows, shutters) and other exterior elements. It can also be used for interiors.
Iron sulphate improves the efficiency of septic tanks. It is very useful and effective in diluting, deodorising and eliminating bad smells while cleaning the pipes and the septic tank itself.
Use: Pour iron sulphate into the septic tank directly or by incorporating it through the toilet bowl. The use of iron sulphate in the septic tank should be done once a year or twice a year at the most.
Dosage: The recommended dosage is 4kg per 100L.
