Hi all
As you can gather from the time I'm writing this post - I'm a little worried about what I have uncovered.
I have just started to renovate an old victorian building. I noticed that the skim on the external wall surrounding the boiler was brittle and falling to pieces. Upon the removal of the skim layer along with a few tiles I found some white powder (minimal) and some white strands which looked like cobwebs.
The sand and cement finish sandwiched between the brick external wall and skim is also very brittle and falls apart upon contact.
I can also see minimal yellow tear drops weeping from these areas.
I've found these 'tear drops' elsewhere too. Only one or two spots in totally different areas.
Can someone please help me.
Thanks
