Fungus is a spotty
black, grey and brown mould which is sometimes stubborn
to eliminate, but if it is not removed before priming, painting
or staining, it can grow through the new coating and ruin
your paint or staining job. Fungus thrives in warm, moist,
low light environments; utility rooms and bathrooms should
be carefully inspected. If it's present, treat the fungal
contamination with a 3:1 mixture of water and household
bleach or specialised fungicidal washes. Sponge the bleach
or fungicidal wash on the fungus allowing a half metre margin
around the affected area just to be safe. Allow it to remain
on the surface for at least 20 minutes, and reapply as it
dries. Rinse the area thoroughly with water and then wash
it with a mild detergent and rinse again. Always wear goggles,
rubber gloves and old clothes when working with bleach.
Never mix bleach with ammonia products;
the combination can release poisonous vapours.
