I have recently started preparing a room for painting. All four walls had a 2 inch dado rail along them which I removed. However, now that the dado rails have been moved I have found that the lining paper on the plasterboard was only papered to the rails and not the full length of the wall. Now I have two inch gap all around the room showing bare plasterboard underneath.
What are my options?
Do I need to remove the current lining paper of all four walls and re - paper the whole room?
Can I use a product such as polycell smooth over just to cover the space left by the rail?
If you're emulsioning the walls I'd take the lining paper off as you'll probably find it would bubble up when emulsioning anyway. Apply a primer to the walls and you're ready to emulsion.
I was thinking about removing the paper, but was worried that it would make it worse than it is. However, i was also thinking of removing the paper and having it skimmed. I suppose I wont find out until the paper is removed.
