    I have a 1930s house, which I've lived in for 2 years. It was rendered, I'm guessing at least 20 years ago. In the last few months I've noticed that in one (south east) facing wall the bricks are showing through the render (you may be able to see in the photo). This has definitely not been an issue before this year. There's no new cracks or anything of note that could have let water in, so I'm just wondering why it would suddenly happen, and also whether there's anything I can do? If I painted it, would it show through?[​IMG]

    It's quite hard to show in a photo...basically you can only see the bricks showing through in certain lights - in direct sunlight you can't see them at all. I'm just a bit worried that if we paint over it, they'll just come through again. I think it's called ghosting.

    If it was rendered 20 years ago it’s in good nick. Ghosting is a strange one to diagnose. It’s all to do with salts and drying processes within buildings. Yours from the photo just looks like it’s ready for lick of paint.
