Hi. I'm looking to apply a second layer of the same lining paper over two strips I'd originally replaced due to imperfections. The other original strips aren't flush with the two replacement sheets so I'd assume higher graded lining paper was originally used on the wall. I had to replace two strips with 1400 graded paper being unaware what the other lining paper was with it being approx 15-20 years old. I've done a test placing another sheet of the lining paper over the bottom layer and it would appear flush. Would I be ok to apply another layer over the two sheets I replaced bareing in mind I've given the first layer two coats of Leyland Trade Contract Magnolia Matt Emulsion Paint? Would this have any effect when the adhesive paste hits the wall?
Thank you in advance for any help.
