Mould from condensation

[paceyjg]

A few spots of mould have appeared around the house, our own fault for not opening the windows enough!

What is the best thing to paint on emulsion to cover and prevent the mould from coming back? (I know that heat and ventilation are the long term solution to the problem).

Also I have a section of old skirting board where the paint keeps blistering off in thin sections. I have sanded it right back and primed it but there must be something in the wood to prevent the top coat from remained bonded? It has started to blister for a second time after about 6 months.

Is there a product that can be used for both of the above problems?

I am thinking Zinsser B I N might be suitable?

Many thanks

I'm just wondering if the blistering skirting is anywhere near the mould spots?
Did the skirting feel damp when you stripped/painted it last time?

The reason being, there could be a small leak somewhere nearby which is then contributing to the moisture in the room and causing the mould as well. A long shot but I've come across this situation several times before.

If there is no leak, clean and kill the mould spores with a bleach and water solution, rinse well, allow to dry and then paint. The best paint for walls with mould problems is usually an acrylic eggshell (basically Kitchen and Bathroom paint in DIY stores), but primer, undercoat and topcoat for the wood should do the job provided the cause of the problem is addressed first.
Zinsser Bullseye 1 2 3 is the better, and easier to use, primer for mould and mildew but B I N can also be used.

The skirting board is in another area of the house and the rest of it does not appear to be suffering from any damp. The house is 100 years old and I think the skirting is original..

A friend suggested SBR could be used for both problems?

I'm not sure SBR is right...as far as I'm aware, it's only use for priming surfaces is for plastering and rendering.
