Hi, what would be the most effective way to red rid of these lines/raised edges,the h/o wants to get rid of the comb effect she had on her bedrom walls.I have not seen the job yet but will be going later on today. Is it a case of sanding away high edges and then priming then mudding and priming again or could you just sand then mud. I know sometimes from previous posts I tend to answer my own question but I think it's down to the fact that since moving here from the UK I seem to doubt my own ability over procedures and therefore need confirmation and reassurance from this site. thanks btw

Regards David
