Unless you used low VOC paint, that smell you smell is pretty toxic. Be aware if anyone starts developing respiratory symptoms. You could try to wash to walls down w/ a nontoxic cleaner. Wear a mask & gloves while washing the walls. If that doesn't work, you might have to paint over it with a Low VOC paint to seal it in. In the meantime, don't spend any length of time in that room & remove laundry promplty so the fumes don't seep into the clothes which will seep into your skin & be toxic. I do a lot of environmental medicine as a Naturopathic Doctor. If you have any more questions or concerns, call the office at ###-###-####
