Step 4 if your rug still won t lie flat apply some heat to it.
How to get a kink out of a rug.
Put a clean dry towel or two over the wrinkled rug then put the hot moist towel on top of that then lay something flat and fairly heavy over the whole shebang i usually pile on a few more.
If you pull it taught while you do this it will get rid of any kinks and makes them a lot easier to hoover.
If the corners of the rug are curling curl them backward flatten them back out and place weights in just the corners of the rug.
This should fix your problem immediately.
Once we put the rug on top of the pad we walked over it a few times to make sure the two surfaces made a connection and that the rug was flat.
Place a piece of furniture or a stack of heavy books on the creases for a few days to flatten them out using weight.
I used to always trip over the rugs in my front room i have a runner over the carpet to the kitchen and one as you walk in.
I cured this by using a staple gun the pile is so deep you cant see i have stapled the rugs down.
