After removing some wallpaper in my hallway, I decided so skim the wall to get a flat finish for painting, the plastering went surprisingly well & after sanding a few rough bits off I used B&Q Plaster Sealer as the pot of paint suggested. After this had dried I put a coat of B&Q emulsion on, this looked ok once it had dried but needed another coat. I then put a second coat of paint on 24 hours later & as it was drying, hairline cracks started to appear in various areas, including areas I had skimmed & areas I had not as only 1/2 the wall needed skimming. These crack have become worse over the last few days. I sanded some of the affected areas lightly, & the cracks dissappeared. But after I repainted, the cracks came back.
Can anyone tell me what could be causing this & more importantly, how to sort it.
