1.
it appears on the stairs leading down to a basement

2.
on the other side of the wall is a bedroom that i know has had a dpc

3.
it appeared a few moths ago but the patches are getting bigger , so there
is
no corelation between rain - infact due to the weather we have had - it
would be the opposite .

Thanks for your help

It may be, or it may be some other reaction.

What is on the other side of the wall, and what is the wall
construction?
When did this first appear?
Does its appearance coincide with any rain?
What is the room used for?

Is this blistering some sort of damp ?

It is appearing on an internal wall - what is it and what can I do to
sort
it out.

Any help / advice would be appreciated

Thanks
