Suddenly I decided to repaint the corridor in a different color, went to the store and bought Beckers paint. It is of course expensive, but its quality is at its best, so I think you can and should pay for it.
The paint fell perfectly on the walls, I painted them in one layer and the surface immediately turned out to be perfectly even paint painted over, I decided to abandon the second layer. I will not say that it was easy for me to apply paint, no, the paint is thick and you need to get used to it and adapt. She painted with a roller and brushes, immediately pick up special ones - for thick paints.
The paint is moisture resistant and, accordingly, after full drying, it can be washed, wiped, cleaned with a sponge, etc. It is tinted without problems, sold in different packaging, I took a 10 liter jar, which should be enough for 60 sq.m. (when painting the walls in two layers), and this in my opinion is a very good indicator.
pros
It turns out a perfectly smooth canvas, economical consumption
