You just arrived home from work, but you see dark-green/black discolouration on the exterior walls of your house. Instead of feeling happy about coming home, you find yourself worried about how your house looks because of all the mould on the walls.

Mould is a type of fungus that grows because of moisture. Besides making your house an eyesore, it also poses a health risk. It can contribute to illnesses such as sinus problems, headaches, skin conditions and even pneumonia—which is why you should consider taking action when you see them on your walls.

Wondering how you can protect your walls? Read the easy steps below.

#1 Check your walls

Before you can take the right steps, you need to determine where the mould is growing. Some moulds are visible, but some are not. Because they need moisture, they tend to grow in sheltered or hidden areas. For instance, it could be growing behind the shoe shelf you keep outside your house.

#2 Do proper surface preparation with fungicidal wash before painting

Clean the fungus by washing it or using a water jet. Then, let the surface dry completely. Afterwards, apply Nippon Malaysia’s Fungicidal Wash. Let it remain on the wall for 24 hours to eliminate fungal spores and wash off the fungicidal wash before painting.

#3 Use a sealer

A sealer is important, as it’s the first layer that needs to be applied to the wall that you’re planning to paint. It ensures proper adhesion of the paint film and delivers long-lasting colours. Not using a sealer would lead to having to do more maintenance work in the future—and money wasted for something that’s avoidable.

#4 Applying quality top coat

Use a good quality exterior top coat, as it is formulated to withstand harsh weather for long-lasting performance. It’s recommended for you to use at least two layers of top coat for your walls.

And there you have it! Four steps for you to start protecting your exterior walls from fungus.
