We treat the the blocks itself not the surface so
we will chisel the affected area on the wall
use part of the chemical to paint the chiselled area.(surface of the blocks)
then we will add the same chemical to the mortar
than plaster the chiseled area
if you are now building too you can add the chemical to your mortar to build your house to prevent your walls getting wet, peeling off or facing such problem
