dissipating mortar b/ween bricks


i have a couple of exposed brick walls that i am restoring and, in some spots, the mortar between bricks is getting kind of sandy and dissipating when rubbed. what should i do to get it nice and solid again ? can i rub out whatever i can get off that is falling off and reapply new mortar ? my skepticism is that that wouldn't hold because it would be just on surface, i.e. would not have too much grip and would fall off soon. is there some mortar-like epoxy type solution that would make sure to stay on forever ?

You can redo the mortar. Do an internet search for "tuck pointing" and you'll get all the answers you need.

i couldn't find any instruction on WWW how to do it. should i just take out as much of the old mortar as possible using a grinder and a diamond blade and stuff new mortar in ?

you don't mention the age of the house so it might be older lime-enriched mortar which's softer than modern mixes,,, the purpose was flexibility for softer brick,,, modern brick's harder so often enriching w/lime's often deleted.

old brick doesn't take well to grinders & tuck-point blades as you'll lose too much of the brick unless you're REALLY careful,,, we still use hammers & tuckpointing chisels for historical work.

my house is celebrating its 100th b-day this year. here is a picture of the wall, from which i am currently peeling the old paint away. what you can see are peeled test patches, all of the paint will actually be peeled off.
