Interior stone wall needs repair...


The house we recently bought has a 12' (8' high) stone wall with a fireplace. The stones are random shaped, from years of use they are dirty & a bit sooty. We will be cleaning them up with some specialty stone cleaner.

One of the problems with the wall is that over the years (50 year old house), people have drilled holes in the motar & there's a bunch of holes. In addition, some of the motor seems to be crumbly, not a lot, but I have a concern that when we clean we may loosen things up. I imagine trying to patch a few spots or fill the holes will leave a different color - anyone have any ideas on how to fill the holes w/out replacing all the motar? Or is that the best solution?

First, don't use chemicals to clean

The main problem with patching old mortar is the color and that old mortar probably will not bond with the new one. Also, some old mortars can react with with a new one.

If you decided to patch the holes, you might consider chipping or grinding out some of the loose mortar first. In order to match the color, you can add a tint to the mortar to give it an aged look, or you can point the mortar in, let it dry good, and then use a light cleaner in a small spray bottle to spot clean and age the spot to blend in with the old.

Good Luck,
