Churn brush is a lime mortar compacting tool used when the mix has been installed and has become stiff enough to pack, not swipe across and smear, in order to push lime securely to the back-up material, expose a little aggregate in order to ?antique? and blend in all patch-pointing work with the surround original mortar. By the action of beating the stiff mortar straight on the tool also helps to reduce unwanted lime spatter on adjacent units.
