iron sulphate
in stock
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.
