We have one large wall in our lounge/diner which measures 26 feet x 8 feet that is covered with artex. After reading on other forums the way to get rid of the artex by many plasterers is having it skimmed over. Our hall/landing walls also have artex on them. This area is 8 feet high x 12 feet with 12 steps on the stairs and the landing being 6 feet wide x 8 feet high. Please could someone give us an estimate with what sort of cost we would expect to pay. Thank you for your time and responses in advance.
