We've got similar problems at our club but with the heavy canvas sheets that we put down to save the town hall staging area, we were temporarily reopened after the first lock-down for about 3 weeks but in that time between we first locked up and then, the canvas has gone all mildewy and smells of what I can only describe as baby sick. Fortunately not as wet to handle as baby sick but I'm not looking forward to dragging out the smelly sheets this Monday even though it will mean the club is back open.
