A comment
I must say right away that I was dissatisfied with the quality of the work done, but I blame myself exclusively for everything. Very irresponsibly approached the base primer. On some forums, 3 layers of high-quality deep penetration primer were advised, on the other 2 layers of deep primer and one Bcton contact, so that the connection between the floor and the base was better.
I primed only 2 times, taking a primer of not the highest quality, and even quite casually leaving a few unprocessed bald spots in the second layer. And here is the result, the water from the solution at the place of bald spots quickly went into the concrete floor and as a result the floor was faster, but small depressions appeared on the surface compared to the general floor level, I had to add specially purchased thin layer level.
The mixture itself is not distributed on the floor surface on its own, you have to work as a rule, then go through the needle roller again. With a thickness of the working layer of 0.5-2.5 cm, the overspending came out 1.5 bags per 10 squares.
Minuses
need to be very carefully primed, overspending material
