ᐅ New efflorescence appearing all over the new retaining wall!

Gray concrete block wall at construction site with soil behind it

Gray concrete blocks stacked, three columns visible, light wall in front

Unfortunately, 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...

Ours are from Weserwaben, the Trendline Long model (for us, it’s also on the higher end of the price range) ... approximately 25 m (82 feet) with around 500 bricks. Painting would be our last option.... Everything is nicely visible and we can enjoy it every day.

Conversely, these are just concrete blocks that have been fired with some paint splashes in them...

I have seen them myself.

You could have just taken some from OBI as well, probably would have been cheaper.

Do you have a construction supervisor?

I'm mainly interested in solutions or experiences—maybe someone has worked with the exact same type of stone... Can I clean the stones using water and a street broom or brush, or will that just spread the dirt even more? Of course, we could have chosen other stones... but we picked them based on our taste and were hoping for a nice terrace wall... Without a building supervisor

I already asked, are they filled with concrete? If so, it takes years for the lime to leach out. I have even tried the cleaner from the manufacturer and even hydrochloric acid, but it doesn’t help.

They are filled with trass cement, and each individual stone is additionally glued with construction silicone. Acid is not an option for us on the surface.

Using acid doesn’t help either since it blooms from the inside. Get used to it or paint over it.
