If they still curl upward place heavy books at each corner for another day.
How to lay a rug flat.
If corners still curl upward flip the rug over and let it sit that way.
First try taking a steam cleaner or a wet sponge and moistening the areas where the curling is at its worst.
The rubber backing keeps the edge of the rug from being pushed up and causing a fall.
Lay the rug back down and press the edges into the floor.
If not there are still other methods that can be tried.
The water will help loosen the fibers and enable it to lay flat.
Roll the edge of the rug up and place the backing on it.
Sometimes the corners won t lie flat even after the rest of the rug relaxes in place.
To flatten corners that are curling upward fold them slightly under so the curve points down leaving them.
You won t have to leave your furniture this way forever but 2 to 3 weeks should be sufficient.
Step 2 fold corners under if they want to curl or roll.
Set the corners back in their natural position.
Ensure that you place at least one piece of furniture on each corner of the rug.
Leaving the rug flat on the floor for between 24 and 48 hours should be enough to train it to stay flat.
Once the water dries there should be some improvement.
Lay the rug where you would like it to go and then rearrange your furniture.
