Its been a week of putting a 1x2x3 board on it with weights and it still wants to curl up. I don’t want to use duct tape. I have to move it to mop so fastening it the floor is out. It is commercial grade and idk why it wont relax on the ends.

Hopefully it doesn’t understand this yet.
It’s just a stupid piece of carpet after all.
You show it some big & nasty looking screws and say: either you stay down NOW or I will have to fix you, and this is going to HURT!
