Cover the floor

If you only want to spray one wall: also stick a strip of 2-in-1 masking tape / plastic foil on the side walls and against the ceiling. Press the tape carefully in the corner to prevent cracks. With the ceiling, it is advisable to secure down-hanging film tot the back with pieces of tape. Also stick the frame wood with masking tape and strips of 2-in-1 foil.
