To prevent recurrence [4]:

• remove the source of the dampness and to dry out the walls as thoroughly as possible;
• improve ventilation, if necessary
• remove the infected paint
• sterilise the surface by applying an antiseptic wash and to allow it to dry before redecorating; and
• use a fungi resistant paint
