Any advice needed!

Hello! I currently have an exterior wall which is in desperate need of repainting, but unfortunately has been ravaged by mold, as you can see in the picture below. What would be the best thing to get rid of this? I've been told about fungicidal paint, is it worth it?

I also have a problem, further along the wall, with the remnants of an old ivy plany which covered the majority of the wall, which is now thankfully gone, though it's left little brown roots all over, as well as taking some of the original paintwork with it. Again, what's the best solution here, regarding repainting?

Thanks for any help you can give!

    Use a pressure washer and a wire brush (where necessary, particularly on the remaining root structures) and the fungicide paint.  What is on the other side of the moldy wall?  Is part below ground?  Can you address the issue as to what is causing the mold?

    Is that decking above the damp course?  How has it been fixed?  Could that be causing a problem?

  • If it's a pre-50s house it may not even have a damp course. It'll just be sitting on the foundations. We have a similar problem with our end terrace. Just have to keep the mortar pointing in a good condition and give the bricks a good painting with either exterior waterprrof paint or moisture repellent. We also ensure plenty of thirsty plants in the borders to keep the soild fairly dry.

    scrub down with a wire brush, kids especially good for this with promise of haribos! Then go over with wire brush removing all of it.. then paint with a decent paint.. by decent read expensive.. you do get what you pay for, so 40 quid a tin is about par for the course..decent stuff equals no worries for 2-3 years, rubbish (20 odd quid) means trouble next year.. just what I found!!!

    I'll ask OH when he gets home, He was a painter and decorator for 30 years. I'm pretty sure it needs a coat of stabliser between cleaning off and painting.

  • Thanks everyone, that's really good advice! I should have mentioned before that our house is a terrace, so our wall is the other side of our neighbour's. As it was built in the 1900's, it's doubtful we have damp course proofing.
