Please could somebody give me some advice! We decorated our hall and stairways a year ago and now the walls are covered in dark scuff marks! The walls were not in fantastic condition, so we had them lined and chose to paint the lining paper, as the area is very large and would have been a fortune to wallpaper! At the time we were recomended to use matt paint as it would not show up the uneven walls! We painted them a light yellow and now you can see every little mark on them! My partner does not want to re-paint the walls using silk paint as we have carpet down and would not be able to lift it to re-decorate! I have to wipe them off but it seems to make the matter worse! We have been told to mix water with pva and paint that over the walls, but I am unsure about doing this! Does anybody have any ideas please or know if there is anything I can buy to sort out the marks and prevent the walls getting marked in the future!
