Can somebody give me some advice about what kind of mortar mix I need to re point the stonework on the front of my house. I would like a gray colour to make it stand out and to match the new gray windows when fitted. Any help most welcome.
Lime sand water, and dye it to the color grey you wish with charcoal or ash. Just make use to use the same measurments each time to ensure a homogeneous color.
There are plenty of guides to using lime-putty mortars. They only drawback is, you must keep every thing damp, for many days. But in the long run, you have a healthier, more flexible wall.
I have used "grout bags" for a long time for applying mortar into a deep clean out of old mortars, however for speed, neatness for final surface repointing nothing beats a hand made Ash "pointing stick/trowel" custom fitted to the joint size and a "hawk" full of lime pointing mortar...
Please let me know if you need more guidance and/or join some of the "pro conversation" for "traditional point" on LinkedIn for guidance...
