I have some cracks in the brick siding of my house to repair. Will be using a ready-to-use concrete mix for the larger gaps and UGL Drylok for the smaller gaps in the mortar. I also have a number of bricks that are cracked that I'd like to use a brick-colored caulk on so that the repairs don't stand out like a sore thumb but I can't seem to find one, what do you guys recommend?
