I didn’t spray anything so I only need to apply tape along the wall, step to interior and along apron. The apron I planned to resurface another day.
I applied duct tape which will stick to concrete. I made sure surface was clean first. Duct tape comes right up if you try and apply over a dirty surface.
After I applied the tape along the apron edge I applied Handmasker by 3M pretaped drop cloth that adheres to the duct tape. Check the picture below. The pretaped drop cloth enables you to work right over the apron.
