So, not only have you splashed out on paint for nothing, but your time spent wrestling with the mould problem has simply swept it under the rug for a short while. According to advice: "Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances.

But what about anti-mould paint? Paint giant notes that the "fungicidal chemicals which repel mould" might lose their effectiveness over time, warning that "mould may reappear if the underlying cause hasn't been addressed or the area wasn't cleaned sufficiently before painting."
