Krend damp circles

[AliMak]

Hi, I hope somebody can point me in any direction to help me resolve a problem with my Krend. 3 years ago I had the bottom half of my semi detached house done with Krend. On just one wall I began to notice circles of what looked like damp. The wall is the bottom right gable end wall. I have had 5 people out to try to solve the problem and nobody seems to know what is causing the patches. I had a damp specialist a few months ago who sorted the inside of the wall as it did have a small amount of damp. The problem has not gone away and looks no better than it did before the damp course was done. I have had the gutter above looked at and the pointing looks okay too. I’m told not use the Krend paint as this will make the building sweat even more. The house had the air bricks blocked 3 years ago so I wonder if that could have caused the problem but I’m told probably not. Any help is greatly appreciated!! I’ve even called the technical help desk at Krend but they also can’t point me in any direction. Besides 3 damp companies calling out who don’t know where this is coming from I’m at my wits end!

Could be wall ties, if the cavity is blocked up at the bottom of the wall with mortar.

Drain in front looks like a crap area
You got pictures of wall before rendering?

Here's a curve ball. I wouldn't be surprised if some hydraulic fluid got onto the wall when you were having the drive done, and then rendered over

Just noticed the airbrick under loo window, that was blocked so do you think that could be part of the problem? If so, have you any idea how I can correct this issue?
