The red covered great. Need to get some grey to do that grey joints
The posts seem a bit big. Also.Need some grey touchup for the grout and that should do it!! Will add those pics when done...
Mortar Joint... I tried a few techniques
Paint over caulk. Looked okay but line still visible
Add sand to paint and touchup. Looked good but don't add too much sand. I felt I wanted more caulk though...
Use Sanded Caulk (tile product) to build up caulk and surface with a bit of texture, then paint. also looked good... I also painted with paint w/ sand. Unfortunately i had too much sand and and to sand down and then repaint, but with all those passes I got some great random texture.
I have some ideas of how I'd do it next time . Will rite those up later. .
I also added a bit more caulk to the bricks and liked the darker color caulk. Let that show thru some and it added color and depth.
6/11/2022 - I'll publish some info on the paint match colors I used and other material in a bit.
