How to Finish Drywall Around Garage Doors

If you want to finish the drywall around your garage doors, you must employ a particular application strategy. Unlike interior drywall, which is typically textured, most garage drywall is left bare. This leaves drywall tape and spackle or drywall mud exposed. Because these surfaces soak up paint at different rates than the drywall itself, they will show up brighter on the finished wall. Professional painters call this problem "flashing through." If you want to avoid this issue, finish your garage drywall a particular way.
