Can You Paint Over Mould?

You should not paint over mouldy walls or ceilings. There are 2 ways to go about it.

First is to use oil sealer and paint over the moudly wall or ceiling. The oil sealer will kill the mould and create a new layer of protection for the new paint. It will take about 2 to 3 hours for the oil sealer to dry.

The second is to apply anti-fungus solution to the mouldy area, wait 12 hours to dry, and finally apply new paint over the wall or ceiling.

Personally and professionally, we will use the former method, which is more effective and less time-consuming.

Consider using an anti-mould type of paint instead of regular ones, as there is a chance that the mould will be back.

Note that this is based on Singapore context.


It is not recommended to paint over mould without removing it first. Painting over mould may temporarily hide the appearance, but the mould will continue to grow underneath the new paint layer, leading to potential health risks and further damage. Proper mould remediation is essential to ensure a safe and long-lasting solution.

To get rid of mould permanently, follow these steps:

  • Identify and fix the source of moisture.
  • Remove the mould using appropriate cleaning agents.
  • Use oil sealer and paint on surfaces.
  • Maintain proper ventilation and control humidity levels.
  • Regularly inspect and address any water leaks or moisture issues.
