removing adhesive line on wall

PURRING

Have recently redecorated my bedroom and removed wallpaper and a border . Now a week later a mark appears all round the room where border once was. Thought I'd done an excellent job preparing walls before applying two coats of good quality emulsion and undercoat. Any advise on what to use or do ,to get rid of the annoying line. thanks

As it is bleeding through, I suggest applying a coat of dampseal or oil based primer to seal the stain that is showing and then paint over with your emulsion. Should do the trick, I am a painter/decorator and have come across this before. Good Luck Purring

By dampseal, do you mean PVA?
I have just matt emulsioned a room, and stuck on a border. I left it to dry overnight. However, in the morning I found odd streaks of adhesive had run down the wall.
I tried to sand them out and re-apply emulsion, but where the glue streaks had been, the paint simply reacted with it. I've got some PVA in the garage, would this do the job?
Thanks.

Hi CGG, I suggest you paint over the stain with an oil based paint, eg primer undercoat, gloss or satinwood, that will seal the adhesive.Just apply a very thin coat. The reason it shows through is because the adhesive repels water and your emulsion is water based.
Good luck
