The interplanetary seams were sealed using the Bronya "AquaBlock Effect".
In some apartments, mold has formed from dampness and moisture ingress through the interplanetary seams, which residents of the house complained about. It was decided to use a polymer waterproofing agent Bronya "Aquablok Effect" which coped with the task perfectly.
The material was optionally tinted gray.
The residents of the house were satisfied!
