Quick answer
To stop a rug from curling up, flatten it by rolling it the opposite way and weighing the corners down for a day or two. Rugs curl because they were shipped rolled, the backing is stiff or damp, or feet keep catching the edge. Corner grippers hold each corner to the floor so the curl does not return. Fix it soon, since a curled corner is easy to trip on.
Free fix vs. permanent fix
Reverse-roll it and weigh it down
- Roll the rug the opposite way of the curl
- Leave it rolled for a day or two
- Unroll it and weigh each corner down
- Warm a stubborn corner with a hair dryer on low
How long it lasts: Works well on a new or stored rug. A lightweight rug, or one on carpet, can curl again within weeks.
Rug corner grippers
A corner curls because the rug remembers its old shape and because feet drag the edge up. A gripper pins each corner to the floor, so it cannot lift. The reverse roll flattens the rug and the grippers keep it that way.
How long it lasts: Months to years, until you take them off. They keep foot traffic from lifting the corner.

Why it happens
It was shipped or stored rolled
A new rug that spent weeks rolled in a box remembers that curve. The corners lift because the backing is trying to return to its old shape.
A stiff or dry backing
Thin, stiff latex or jute backing does not lie flat by itself. Cheap lightweight rugs are the worst for this.
Feet, doors and vacuums
Feet catch corners and pull them up. A door that brushes the edge or a vacuum that tugs it adds a little more curl each week.
A rug that creeps on carpet
On carpet, a rug slowly walks and bunches up, and the edge folds over. Nothing holds it still, so it curls again and again.
Damp air or a damp floor
Humidity or a wet floor can make the backing swell and curl the edges.

Do these in order, starting with the simplest.
-
1. Reverse-roll the rug
Roll the rug tightly the opposite way of the curl, with the pile side facing out. Tie it loosely with string and leave it for 24 to 48 hours.
-
2. Flatten it and weigh the corners
Tool used: Heavy books or furnitureUnroll the rug on a clean, dry floor. Set a heavy book, or a leg of a sofa or table, on each curled corner. Leave it a day or two.
-
3. Warm a stubborn corner
Tool used: Hair dryerOn a fabric- or jute-backed rug, hold a hair dryer on low about 6 inches away for a minute, then press the corner flat and weigh it down while it cools. Skip heat on rubber backings.
-
4. Pin the corners down for good
Tool used: Rug corner grippersFit a gripper under each corner, or run a strip of double-sided rug tape along the curled edge. Press for 30 seconds. On carpet, use a product made for carpet.

When free fixes aren't enough
If the rug lies flat for a day and curls again, nothing is holding the edge down, so grippers are the fix. If the whole rug slides or bunches on carpet, a pad made for rugs on carpet does more than corner grippers. Do not use tape on a finished wood floor unless the label says it is floor-safe, since adhesive can pull up the finish. A rug with a cracked, crumbling backing is worth replacing.

How to stop a rug from curling up for good

- A whole edge lifts: double-sided rug tape along the edge.
- The rug slides and bunches on carpet: a rug pad made for carpet.

What to skip
Tucking things under the curl
Cardboard or a folded towel under the corner makes a bump you can trip on, and the rug still curls. Skip a hot iron or steam too. Heat can melt synthetic fibers and backing.
