I was looking at a friend's wall the other day, it had previously been rendered and tiled but the tiles started falling off and the render was hacked away.
There is evidence of effervescence but I did notice a couple of bits in some of the brick mortar that almost looked like thick spider webs.
Above is part of the wall. Below is a zoomed in photo 0f one of the web type areas.
I pushed the web with my pocket knife and when I removed the pressure, the web bounced back.
The room is a kitchen with a recirculating cooker hood. The render was removed last year.
Might it be dry rot?
