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.
(This is a stock picture of the same mat.)
You can’t attach it to the floor, but can you use some good double-sided tape or super glue to attach some steel weights to the underside of the corners?
Any home improvement store should have some flat bar. 1/8" or about 3mm should be flat enough to avoid a tripping hazard, but check local regs for commercial properties.
