lining paper puffing up

[asalcedo]

I am painting my home with professional decorators.

In some wall areas the wall paper has puffed up after applying tw coats of matt emulsion. The swelling is very evident, especially i corners and some seams.

We are going to try to fix the problem by regluing or, if this does no look good enough, by stripping out the wall paper, re-lining an painting.

The problem is that the swelling is happening too often:

After painting one ceiling the lining paper also puffed up. I told the to strip and line, which they did. However, even after they put bran new 1200 lining paper, some bubbles have showed up, especially nea seams.

The wall paper in all the stairs and landings was in reasonably goo condition but I told them to strip and re-line because I did not wan any bubbles. They are stripping it now but I fear that it is going t swell up again even with new lining paper.

We are using Dulux Trade emulsion, normal and Diamond grade.

What are they doing wrong?

Thanks,

Antoni

Probably not soaking the paper for long enough, or it's drying before it's hung, or not brushing it enough, or the surface to be covered needs sizing (unlikely as it's just been stripped). Paper of this thickness really needs a long soaking time (or *real* soaking, in a trough). How long have they been leaving it to soak?

Are you using Solvite walpaper adhesive? If so, try genuine Polycell next time, allowing it to really soak into the paper before sticking to the wall.

Not sealing the wall, or not soaking the paper for long enough. The heavier the paper, the more important it is to do both.

What? Do you think they need diluting (they're a bit too thick)?

What he said. When pasting you should align one edge of the paper with the edge of the table, and run the brush right off the edge in a criss- cross motion so nothing's missed, then repeat with the other edge. Make sure that the paper hanger isn't working faster than the paper paster, otherwise it won't soak long enough - putting more paste on is no substitute for letting it sit for a few minutes so it softens.

Perhaps you have some discarded sugar puffs stuck behind the paper?

Thank you for all your replies.

I do not yet have the answer to your questions, but I will try to fin out.

I have not had a chance to look at how the do the papering.
