How to Attach a Green Screen to a Wall
Green screens allow graphics to be added to a filmed broadcast, either in post-production or in the case of newscasts in real time. Green screens, so named because quite literally they're a blank field of green, are anchored to the walls of professional or makeshift television studios much like cinema screens.
However, if you're a budding filmmaker who needs to put up a screen without much fuss, there are alternatives.
Lay the screen out flat. If you've purchased a less expensive "sheet" style of screen, smooth out all the wrinkles with your hands. In either case, whether it's a sheet or pre-framed screen, spray the backside of the screen with fabric adhesive.
Place the screen against the wall and press all over the sheet to ensure firm contact is made between the adhesive side and the wall. Depending on the size of the screen, you may need a stepladder to help you reach the top of the wall. If the wall is brick, or the screen will be used for longer than a few hours, proceed to Step 3.
Spread a bed sheet flat on the floor and lay the dowel rod that measures the same length as the sheet across one edge of the sheet. Roll about an inch of sheet over the rod and sew the gap in the sheet together to weigh down the edge. Hammer the right and left corners of the sheet opposite the dowel rod end into the wall using floor tacks. Use masonry nails nailed into a joint between two bricks if the wall is brick or block.
Smooth the wrinkles from the hanging sheet and spray the backside of the green screen as you did in Step 1. Lay the screen over the hanging bed sheet and press down to ensure a tight seal. The adhesive will last considerably longer when used between two fabric types versus using it between fabric and a wall surface.
