Hello Welcome to the site. The best way to get rid of it would be to scrap the high spots off and the re plaster. I believe it's not going to cost that much more. Best to get an on site survey/quotation done, this is a free service to you and you will get 3 quotes. Simply post your job onto rated people's site. You are not obliged to go with any of the quotes- but every job that's posted is paid for by the relevant tradesmen .if they contact you that means they are interested in your job. If one of them are awarded the job then great news for you both. ratedpeople.com Regards Michael
