Went from 3 courses a day to 8 after my trowel grip fix
I was hitting a wall at 3 courses a day on a garage job in Mesa because my hand was cramping so bad by noon. Switched to a wider trowel handle and started soaking my hands in ice water at lunch, and now I can lay 8 courses without slowing down. Anybody else have a grip setup that got them past that afternoon wall?
