Hi I need help on this subject please,
I'm searching for the definitive answer as to whether or not there is like a spray on liquid which will firm up house stone foundation/wall mortar.
These are turn of the century 1900, which the mortar is very crumbly. It is constantly slowly falling out.
I know home improvement books say to scrape out some of the old mortar and repoint the grooves with new mortar after wetting the surface with sprayed water.
*BUT I have seen some old 1900 walls in restaurants where the mortar seems firmed up and no longer crumbly as if it was sprayed with some kind of firming agent.
Otherwise is repointing the only treatment for such walls?
Thank you for your time and knowledge!
