Hello everyone,
Last year, I built a wall using formwork blocks. Now it’s time to plaster it. I have never done this before and am hoping to receive plenty of experience, tips, and ideas.
My plan was to first use mortar to even out the “irregularities,” then clean the surface, apply a primer and let it dry well. Next, I want to apply the base coat (scratch coat), let it dry again, smooth it out, then apply the finish coat (top coat), and finally place coping stones on top of the wall.
What do you think of this approach? Do you have any advice on which products would be best for this? I am particularly struggling with choosing the right coping stones and finish coat. Perhaps someone has some ideas or even alternatives for me.
Attached are two pictures of the wall, which is 22 m (72 feet) long and 75 cm (30 inches) high.
Thanks a lot Best regards

Did you stick the cladding directly onto the wall? Yes, I did. I should mention that one or two blocks have become a bit loose over time, probably because moisture got behind them. Overall, though, the cladding has held up well for 2 years, and I still like how it looks. It can definitely be optimized, but we are satisfied.
