Damp proofing before painting

sakimotosan

Hi all,

I was having a problem with mould in my apartment which has since stopped since getting a dehumidifier. I plan on removing the existing mould and repainting as some of the surfaces look quite dark as a result. I would like to apply some sort of 'damp proofing' before painting to lessen the likelihood of this happening again but I am not sure of the best course of action to take; any suggestions?

Thanks in advance!

p.s. cheap and cheery would be preferable!

Apply bleach to the black parts of the wall, leave it on for 24 hours. Open the window.
Wash it off the next morning.

To prevent mould returning, you need to air your rooms as much as possible.
Condensation is a cause of mould, so when you wake in the morning, open the window.
Same when you're in the shower/kitchen etc.
Airing rooms is vital in the battle against mould.

In the winter time it will not help, because making room cold, the moist will condensate in the room before getting out as well as pressure will move moist deeper in the structure. There's 2 things to prevent mould, it's air circulation and heat, because heat will dry the structure and air circulation will move moisture out!!!

I believe you can use tea tree oil to get rid of the mould instead of bleach. If it works it'll be better for your health.

If its just the discolouring your trying to do away with, use a oil base paint on the patch's.. and then finish with the paint your use on the rest of the walls.. This is just a cover up, and its not addressing the problem.

Thanks folks, I will take those into consideration. I might give tea tree a go first as I don't fancy sleeping with bleach fumes in the vicinity. I own the place; the dehumidifier seems to be keeping it under control so I may try the oil based suggestion before painting properly.
