For the production, we built a wall prop using a sturdy wooden frame with plywood, measuring 2.5 x 1.25 meters. During filming, we used the wall three times, adapting it each time to fit the specific purpose. For the application of Mammut adhesive, we used a plywood wall painted white. For the application of acrylic sealant, we attached drywall to the plywood. For PU foam, we flipped the wooden support frame and inserted a plastic window. One wall has multiple uses and can be reused repeatedly, making it both economical and environmentally friendly.
