Hey we are having trouble we have put lining paper on our walls ( alcoves were hell!!) we are now painting the wall but the paper is bubbling. There are new bubbles forming as we are painting the wall help please?

Thanks

It sounds to me like you have either not sized the walls where you have filled or have maybe not pasted all the wallpaper and maybe missed bits here and there.

Was the wall painted before you put wallpaper on?

Dont put any more paint on and see when it has dried if the bubbles go sometime they can do it's 50/50

Paint one coat only and leave to dry overnight. It will look better in the morning.

If you paint it again whilst it is still moist at all, the paint may reinforce the bubbles, making them permanent.

I am not great at papering at all so I am always careful to size the walls at least once, more if it soaks in really fast. I then paste three or four lengths, paste the wall with a roller and then hang the lengths in the order that I pasted them.

A Professional would not paste the wall as well and my method certainly uses more paste and takes a bit longer, but it does mean that the paper soaks properly and crucially, any edges or patches of paper which are missed when pasting, will benefit from the paste on the wall leaving no bare patches and this no bubbles.

Jozeffo, do you paste your paper with a roller as well? - I find that it covers better and hardly ever miss any bits.

Yes I do use the roller to paste the paper. Only for lining paper though.

Jo,
If you have sized the walls , you shouldnt need to paste the paper and the walls. See where your comming , but just using extra paste. I prefer to use a medium roller for pasting, be it lining or finish paper.

I shouldn't need to and I concede that professionals would do it differently, but one small miss on a porous wall can cause a problem and this eliminates the chance of it.

Not having to worry about the care when pasting allows me to focus more care on the hanging and cutting.

Practice boy , practice
For my sins i love paper hanging.

I'd never done that before until I hung a border last week. Rather than get a smaller brush for applying the past I used a 4 inch medium roller. It made it so much quicker, covered better and made less mess on the table either side of the paper. I will definitely use a 9 inch roller next time I am pasting normal-width paper.

I'll use a 9" microfibre roller for paste the wall, but old habits die hard. Still using a 6" flat wall brush for pasting. I did try a block brush for a while but couldn't quite get used to it. Maybe my age.

Try it mate - I bet you don't go back to the brush.

Same as Jozeffo on this, paste a few lengths along a wall then i paste my paper.
and i was also told about knotting on lining but must admit i dont do that, just leave a gap, paint seams, fill, then 2 coats,
just seems to work better with my rushed non perfect hanging!
