How bad is the butt joint to flat joint connection?
I did my butt joints first and then my flat joints and without a light they look fine after sanding but with a 2500 lumen shining straight down the wall I see unevenness from where the two joints meet. I’m wondering if this is because I did the butt and flat joints at separate times, but I did wait for the butts to dry before starting the flats. How bad is this?
