This is my first attempt at wallpapering.
I have made sure the plaster surface is sound and free from dust and am using a 1000 grade lining paper.
The problem I have is when I put up the lining paper it has air bubbles showing.
I do not know if it is because I used too much wallpaper paste or what?
I applied the paste to the paper and then hung although my toolkit says to apply the paste with the roller to the wall and then hang, would this cause the bubbles behind the paper?
