    Hi Bikash,

    I am sorry, but it is not entirely clear from the photo you posted what the problem is. If I understand correctly, the paint that was on the wall is now coming off in pieces?

    What color was the lower part of the wall painted 4 years back - the purple or the orange?

    Is the wall made out of concrete?

    It looks like the lower part of the wall was painted and then covered by concrete or something similar. The hard covering looks like it is breaking off in places and some of the paint is now being seen. I am not seeing an area where the paint is removed, maybe seeing glare or powdery residue from where the hard layer was.

    Could you re-post your question, it is not clear what you are asking?

  • It looks like there may be a moisture problem that;s causing the chipping.

    Okay, so I'm thinking that the Thinset that was used to smooth the surface of this concrete was not properly cured and sealed before it was painted. Moisture that was in the concrete originally came to the surface and eventually flaked off with the paint. If you don't have the original colors, you'll need to start over. Consider this an opportunity to refresh and repair, not as a chore. First, sand off the remaining paint and concrete flakes and clean that up with a vacuum cleaner. Trowel on some concrete patch (Thinset) and smooth it the best you can. LET IT CURE. If it's lumpy, you can sand the area again - and vacuum up the dust. Then you'll need to paint on a primer/sealer before you repaint the wall. It isn't really as complicated as it sounds.

    I would recommend sanding off any loose paint and then using cement paint to re-do. It comes in a variety of colors and can be purchased at your local hardware store.

    I really think you have a moisture issue that you need to address first.

    I agree with the posters about they were some moisture problem. Perhaps observing what’s on the other side might be helpful to solving the problem where the moisture is coming from. Otherwise after repainting —it’s going to happen over and over again.

    I agree about moisture being an issue. Before you panic - is this space below grade? Do you have HVAC service to the area? If it's below grade w/o it's own air and heat circulation you likely need a room dehumidifier.

    You have a damp issue, have an expert or two to come and look and give advice, a price and time it will take to solve the issue. Ask what will need to be done to sort it for good! Then you will know if it is within your abilities to do it yourself or if you have to find the money to get it done for you sooner rather than later. Best wishes.

    Hi Bikash, High humidity levels in the basement will not only result in the growth of mold but will also encourage the peeling of the wall paint. This is because sealers and paints used on basement walls are often porous. The paints therefore absorb the moisture from the air. The water is then also absorbed into the wall, causing paint to peel off. Here is a link to show how to paint the concrete,

  • Is the wall concrete? It’s a bit hard to tell what’s going on but if it’s concrete, there could be a moisture issue causing the (incorrect type of) paint to peel. You’ll need to scrape the peeling away and repaint with the proper paint.

    Yes, I too think that the problem could be resulting from a moisture issue. I was even wondering if the black along the bottom of the wall/floor seam could be mildew?

    It does look like a concrete wall. I would check to see what's going on, on the other side of the wall. Generally, water should be diverted away from the house, and any ground pitched away. Sometimes, especially since it's a new issue, something has moved, blocked or the contour of the ground changed. Something as simple as a blocked gutter can really create a problem. Divert the drainage away from the outside wall, or make any other corrections before removing the old paint and repainting. If it is a concrete wall, there should be waterproofing on the outside. Good luck and stay well!

    Hi Bikash: What you can do is to use a wide putty knife to clear away all of the flaking paint, as far as you can. Even if it's far away from the original messy spot. Then, use a concrete repair to fill in the area, making sure that there are no bumps where the repair meets the paint. Let it dry and then paint. Seeing that you have red, I'd use a primer over the entire area to hide the red. Here's a site that shows the product I'm talking about:

    Good luck
