Stains on the plaster and visible joints

the cause - as it seems to me - is that it was done "as cheaply as possible." Understandable and at first only a little "stupid." An important detail in this regard, I find: Does it have technical consequences that get worse over time? As long as it remains a problem of appearance, one can live with it. If it affects the substance, something should be "done."

There is an ETICS behind it, so it would be bad if the plaster already looks like this now. You can imagine how it will look behind it soon.

I am often annoyed by the many abbreviations in the forums, which I also often cannot "translate" through an internet search (this time I think I didn’t try :oops:) and where it is always assumed, of course, that everyone knows what is meant :( (if only – like with the smilies – an explanation would be displayed on mouseover :rolleyes:) thank you for the explanation :)
