The appearance of small black spots on the ceiling, which gradually get bigger, is a clear sign of a problem with the accumulation of humidity or stagnation of water which must be identified and resolved as soon as possible.
Those black spots are mold, whose spores are harmful to our health especially if we have respiratory diseases such as asthma or allergies. While you figure out the cause (which may not be in your apartment if you live in a condominium), you can take steps to fix the problem before it’s too late.
Repairing a ceiling affected by mold is simpler than you might think, and below we suggest how to do it step by step. You need:
a pair of gloves
a bucket
a broom
a wooden pole
a brush
a spatula
300 grams of putty
150 ml of waterproofing liquid
500 ml of water
