Damp survey; Mould or Efflorescent salts?

Sometimes, as a damp and timber specialist I'm asked to look at mould and when I get on site I find that the 'mould' is not mould at all, merely salts. Efflorescent salts formed as water in plaster or on wood dries out, can sometimes look very like a white mould.
This damp survey in Harrogate, West Yorkshire was a chance to demonstrate what to do if you are just not sure if the white stuff is mould or salts.

Another great video, which shows the benefits of using a qualified experienced PCA surveyor. Good diagnosis is the key!

I'm training as a damp surveyor and I must say, your videos are the most sensible and informative related ones I've found. Good work. Thanks.
