Used to butter my bricks for years till a mason called me out on it
I always thought buttering the head joint with a thick blob of mortar was the right move, made me feel fast. Then a job in Denver last fall, an old timer watched me lay a whole wall and said 'you're just making a mess, let the trowel do the work.' He showed me how to put just a thin smear on the end, and my joints actually came out clean and uniform. Now I barely touch the buttering and my walls look way better, but it took me like 12 years to unlearn that habit. Anyone else have a basic technique they had to relearn after thinking they had it down?
