I have no idea what the problem is, but I am trying to spackle a few holes and some of the old paint came off as I was smoothing out the spackle. I took the edge of the spackle knife and was easily able to sc**** off a layer of this paint. Using a damp rag I tried wiping the area clean and all it did was take off a hand sized area of paint. What is this that I'm wiping off? Underneath it's slightly bumpy in texture but feels somewhat glossy. Any help would be appreciated! I'm trying to figure out whether I should keep washing the wall off or not.
