Parging a spalling brick wall
I just had the entire exterior back wall of my house parged. The bricks were so old and damaged that they were literally crumbling and turning to sand at the touch. Initially I was going to have them pointed/repaired, but the mason advised me the bricks were too soft at this point to do that. After all of this happened, I noticed a different kind of brick used on the front of my house was taking in water and damaging the plaster interior walls. This was after two weeks of periphery rain from hurricanes. To make a long story short, I did research, found this site, and read articles for hours and hours. What a great resource this site is!!! Now I understand that there are different kinds of mortar and brick, and my bricks are the old sort (circa 1915) that require lime based mortar. I checked with the mason to see what he used, and he used N type mortar with a psi of 750 that’s better for soft bricks like mine. I checked and it still has cement in it. Am I worse off for having this on my old, spalling bricks? Please advise.
