Recently I painted walls in bathroom with latex water-dispersion paint. The walls were quite even, except some minor defects and a few major ones. I applied "acrylate" filler (that's what the can says) on those defects. In case of major defects I appiled about 4 millimeters of filler. I let the filler dry out, sanded it and applied two layers of paint.
Now I see that the paint coating is slightly darker where I applied a thick layer of filler. I suppose the filler hasn't dried completely and now releases moisture and this propagates through paint.
Do I take any special measures or just wait till it dries up? How long should I wait? Have I screwed it?
