Hi, bedroom had a walls re skimmed and although it is clearly still drying the two external walls and a couple of smaller areas on the internal walls all have these marks on. My plasterer said to just buy some zinseer cover stain. Do I just cover the marks or all the walls. The marks cover a large area. Not planning to even do mist coat yet but leave it a while longer. Would you need a must coat over the stain block ?
