Can anyone recommend a good fungicidal wash for interior masonry walls? I've found a few washes but most seem to be for exterior use, so I'm not sure they can be used indoors. I'm needing it to deal with a black mould problem. The underlying cause has now been sorted we think but we're left with the disgusting discolored walls which I plan to clean, hit with the fungicidal wash, then paint with Zinssers anti mould paint. But I need some advice about the best wash to use. Any help greatly appreciated. Cheers. Reg
