Just now I told you my experience of pouring liquid glass onto an old concrete floor, a Soviet cross. It is so old that the top edge would constantly turn to dust when trying to sweep. Cleaning the garage was a pain. The dust never stopped.
Therefore, I decided to pour it with liquid glass cheaply and angrily. Thus, dust the surface. I managed it. Spending only 12 kg of silicate glue on the surface, for 24 square meters of garage ...
It's been two years
This period is sufficient to summarize. You can watch the video:
Or look at the photo, below you see a concrete floor covered with liquid glass after two years.
If you zoom in and take a picture, you can see a white "husk".
This is the glue that the water got on. Exactly where the puddles were.
In other places where the water did not stand, the coating was preserved. And I don't remember about dust. I am pleased with the result. If you use the garage for its intended purpose, that is, store the car and drive in in the rain. Such coverage is contraindicated for you. It will fall off everywhere. And if you use it as a workshop. That can be done, but they say that there are better options.
