Penetrating damp
- Thread starter Kat183
- Start date
It has different settings on it. I had it on the building setting. It has a wood setting too.
You can see staining and sometimes it feels a little wet to the touch and looks shiny/slimy
All the wall paper was wet so I removed it. Had it repointed externally but still wet patches
Useless in brickwork as it’s surface only detection which does not indicated damp .
Any suggestions on a more comprehensive assessment I could do? Because there are 100% wet patches. I just used the meter because it would be hard to see the patches on photos
I think I can see some damp staining, alongside the window reveals.
That meter is not calibrated for anything other than timber. That's a fact despite any settings it has. And you can put it on almost any material and it could get a reading, but that's not in itself an indication that there is excessive damp.
Plus you're measuring the surface only, and salts, wallpaper paste and the kettle you just boiled are all skewing the readings.
It's how the readings are interpreted that is crucial. And that needs training and experience.
The best thing to use is your eyeballs, and you need to be seeing prominent damp stains, yellow/ brown and maybe white salts. Those photos are not showing any.
Penetrating damp would be visible after rain and then dry off - leaving tell tale marks. Again, the photos don't show any.
