    Hi all,

    First time poster here. I'm very green when it comes to DIY. My girlfriend and I purchased our first flat in the summer so please excuse any naivety I may demonstrate.

    We purchased a newly refurbished end of terrace basement flat. Building itself is circa 1880. We bought from developers. Suffice to say when we were buying superficially at least the place looked immaculate but a few issues have come to light recently.

    The main issue relates to the end wall which is subject to some moisture penetration and we are going to get that stripped back to bare bricks, treated and redone. This post is not about that but may be related.

    When we've had damp specialists round we've pointed out two areas which has left them at a bit of a loss. The first (see first photo) is about 140cm up from the floor immediately when we enter through the front door. This wall backs on to the old coal shed which has long since been blocked up. The paint was bubbling and today I've had a bit of a go at knocking the flakey paint / plaster away and have got as far as the photo attached. What should my next steps be?

    Please ignore the apparent black spots on the photo, my iPhone lens is faulty. Would I be right in thinking the orange / dark material is the plaster and everything else is either paint, or potentially a polyfiller type material?

    The second area (see second and third photos) are on an internal brick wall. The builders who have seen it say it looks like a combination of cheap paint applied to plaster that was not completely dry. Does that sound about right?

    What should my next steps be? The paint I've got rid of so far has only been that which has come away freely. I know that the rest needs removing. I'm not sure if it is just a case of scraping and sandpapering?

    First issue:
    I have the same issue. damp on my wall as I enter my front door. Couple of questions:
    1, Is this wall "dot and dab"? (plasterboard dabbed with adhesive onto an external brick wall)
    2, are there any other signs of damp patches on this wall?
    3, is there any plumbing (central heating etc) that pass behind this wall?
    4, would you say there is a layer of condensation on or around this wall?

    Second issue:
    Flaking due to cheap paint is unlikely, but plausible. However when painting any freshly plastered wall, its best to leave a week or so before applying a "mist" coat, this is a 50/50 paint/water mix which is applied first, this mist coat acts as a primer for your 2/3rd normal coat. This method will prevent paint flaking in the future and I suspect is the main cause.

    Solution is to lightly sand the area (nothing too course) apply a mist coat and finally your 2/3rd coats.

    Hope this helps
