How to kill mould underneath house?

Mobile home on 1m steel supports. Long term shower leak fixed temporarily until reno next year. How do I kill mould on underside of house as water leaked through and onto the ground.

Mould growing on small part of wooden beams, larger area of yellow tongue board.

Too large an area for a spray bottle and I'll be working pointing upwards (or sideways with less upward angle)

This too is temporary until next year as the floor will have to be ripped up for the reno.

Thank you.

Hello @SOS_29

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about mould.

I propose using Concrobium 3.78L Mould Cleaner Refill Jug to treat the mould infested area. I suggest using Silvan 5L ECO Hand Sprayer to spray the affected area. Please make sure to wear personal protection such as Pro-Val Hazguard MP5 Disposable Coverall, enclosed shoes, disposable gloves, safety goggles that seal around the eyes and a proper respirator with filters. The purpose of all that protection is to prevent the mould spores from infecting you and to protect you from the spray as well.

Please note that if the infestation is larger that 9 square meters and the mould returns despite the repeated application of the mould cleaner, I recommend engaging the services of a professional mould cleaning specialist to service your home.

I also recommend having a look at this guide: How to control mould in your home

If you have any other questions we can help with, please let us know.

This sounds perfect Erik. No washing afterwards with a hose or trying to use with a broom and 30 secs - harder work for an old woman but which would also disperse spores in the air. This product is a quick gentle spray that dries and crushes the mould. This sounds perfect. Just hope it adheres to marine ply too. Previous owners attached it to the underbed to support warped flooring 🙄. Using the spray pump will make it easy doing it a few times though. Very happy with this suggestion 🙃

Hi @SOS_29,

It will be effective on most surfaces, including ply.
