| This spotty black,
grey and brown mould 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. Fungal contamination thrives in warm, moist,
low light environments. Algal contamination on the other
hand proliferates is the presence of light. Carefully inspect
northern exposures and shaded areas of the house, around
the trim and under the eaves, where the sun seldom shines.
In addition to fungicidal washes; another effective removal
method is to prepare a 3:1 mixture of water and household
bleach. Apply the bleach to the fungus or algae allowing
a half metre margin around the affected area. Allow it to
dry for at least 20 minutes, reapplying 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. |
