Finally got the 14 one-foot black granite edges I needed! My challenge was how they were going to stay put as the mastic got hard enough to hold them in place. I had an idea of what I needed but wasn’t sure if it existed and sure enough…. the 3-way clamp! At $8 each, I did NOT want to buy 14 of them to get it all done at once so I just bought 3 and will just have to do 3 at a time. If I get up 1/2 hour earlier each day, I could then do 6 a day if it hardens enough in 12 hours.
Then, I grouted the walls with just plain white, non-sanded grout. Nothing to this really. Mix, spread, wait, wipe, wait, wipe, wipe, wipe.
Running total: $745
