Hello or rather help! We have started casting a concrete staircase with 6 steps, 2 meters wide, 5 meters long, a landing outside the door, and steps in each direction. The staircase is unheated and has no roof. We are casting in sections.
We mixed our own concrete and got the recommendation to use cement, stone flour, and gravel 4-8 to cut costs 🙈. Just from that, we should have understood that there are no shortcuts. The result was a disaster and it looks like lecca. Just have to break it away. We decided to use sand, larger gravel size, and mix with cement. But then my husband got a recommendation to use road crushing instead and just mix with cement and water?
Those of you who have cast a concrete staircase and mixed your own concrete that holds well over time, what have you used? Since we are casting in sections, color variations will occur. What is recommended for a final finish that holds over time? Plastering, slamming, which product?
