If you decide to finish the garage and paint over the white stripes left by the contractors, you may want to paint before adding any cabinets.

The interior of your garage is also not exposed to outside elements such as rain, snow, and sunlight, so it doesn’t necessarily need the chemicals in exterior paint.
Both exterior and interior paints have different chemicals inside of them, but they have a different consistency. Exterior paint is thicker, whereas interior paint is thinner and not mold-resistant.
Available in various colors and glosses, interior paint won’t scrub off during cleaning.
If you notice white lines on your garage walls, don’t worry. The white lines on your garage walls are perfectly normal and don’t require much attention, fortunately. Most garages are left unfinished due to costs, hence the white lines.
It’s okay if you don’t want to paint over them, as long as they don’t bother you.
However, if you decide to paint over them or make your garage a cozy room where you keep your belongings or spend time, then painting over the drywall stripes would be a great project to invest some time and money in. Good luck!
