This kept my constantly curling rug straight and it has not curled against since! Just straighten out your rug and apply the product--its as simple as that
Just peal the backing of and stick to the rug
I did use the furniture grippers n I'm puttin a future purchase for the rug gripper
My corners are not lifting up & it also gives a little weight to keep the runner in place
It will make your rug last longer and keep you from going crazy
Works like a charm, easy to install and does the job
