- Using paint from one can to roll the walls and another can to cut in
- Brushing and rolling at different spread rates
- Cutting in the entire room before rolling, allowing edges to dry unevenly
Causes:


RECOMMENDED SOLUTIONS
- Always use paint from the same batch or mix all cans together before starting.
- Cut in and roll small sections at a time to keep a consistent wet edge.
- Work from wet to dry and feather the edges of your brush and roller strokes.
