Blunt Tool
So leave to dry? As I did with Mapei wp200 matThe trick I found with the TM mat is to get the first roll down straight. I cut to length and then roll back up as tightly as possible, get the addy down (3-4mm notched) and then slowly lay down next roll. I use a weighted roller similar to what Karndean floor layers use. I try to butt the rolls as they are laid.
I get what you mean about it moving so I always try to work back out of a room so you have neither tools, tubs or indeed yourself on the mat at any point if possible.
