Can I ask whether you removed the bitumen strips before laying the marmot. I am about to be faced with the same challenge and wanted to know how you got on. I am about to lay marmot onto a floor which had parquet flooring. There is currently remains of bitumen. What adhesive did you use? Did you also screw the marmot?
