SchnubbiUnfortunately, our newly built wall has become an eyesore... Our terrace wall was supposed to be a highlight, but now I just want to look away. The manufacturer only says that we have to live with it and that it will disappear over time due to weathering. We were not aware of these issues with concrete blocks and approached the wall rather naively. What options are there? Without damaging the wall, making it look even worse, or just watching and hoping that after 3 years it might finally look like the wall was meant to...
I call it naivety... The bricks were stored at the dealer’s for two months, and after about two weeks, the bricks started to change like this... I took pictures and asked what it was... The answer was that it would disappear due to weathering.
My impression was that concrete dust had gotten wet and simply ran down the bricks, but apparently it goes away with water! I didn’t google or look for any information on what could happen with such bricks... The shock came when I wanted to clean the bricks at home, which were already installed of course... I completely trusted my local dealer.

That’s exactly the situation. The air was full of dust, and then it rained a bit. The concrete ran down and then set.
A wire brush, water, and some strong arms—that should take care of it. A pressure washer could also work, but it can damage the stone.
Try it first on a small section of the wall. Let’s say four stones. Wait a few days. If it goes well: happy scrubbing.

If you enlarge the image (the quality is great), it looks to me as if something has run onto the top row (not from inside over the edge but onto the edge!). And only from above. The streaks can clearly be traced from top to bottom.
Maybe something was still on the (over the) pallets at the dealer? Scraping off and chemical analysis? That would provide clarity.
If this is something that shouldn’t be in or on the stone (according to the manufacturer), it is a “foreign” substance for which the dealer / supplier should be responsible?
