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. In some forums, 3 layers of high-quality deep penetration primer were advised, in others, 2 layers of deep and one Bctoncontact, so that the connection between the floor and the base is 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 in 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, it was necessary to add a 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 went 1.5 bags per 10 squares.
Minuses
need to be very carefully primed, overspending material
