Changing Mortar Colors in the Field - Limestone & Brownstone [Video Demo]
Dennis Rude, Stonecutter and President of Cathedral Stone, demonstrates how to fix/tweak limestone and brownstone mortar colors on the job site.
There is one video for limestone and one video for brownstone.
These are longer videos, but, if you’re doing this kind of work often, they have tons of helpful information for you.
