How to Flatten a Rug and Get Creases Out

After you’ve found your dream rug, it can be disheartening to unroll it and discover wrinkles, ripples or curled edges. Whether it’s a new rug that’s been rolled or folded for delivery, a recently washed rug that won’t settle, or an older rug starting to lift at the corners, creasing is a common issue. Rugs can also struggle to settle when placed on new carpet, which is why learning how to get a rug to lay flat on new carpet is just as important.

Aside from affecting how your space looks, a buckled rug can become a trip hazard if left unresolved. At Rugs Direct, we know how important proper rug care is, so here’s how to help your rug lie flat.

How to Get Creases Out of a Rug

If your rug has ripples or dents, moisture and gentle heat are often enough to relax the fibres. This is one of the most effective ways to get creases out of a rug without causing damage.

Steam works particularly well, but it needs to be used carefully:

1. Place a damp tea towel over the creased area.
2. Press an iron on top in short bursts, never directly onto the rug.
3. Lift and repeat, allowing the steam to penetrate the fibres evenly.

This method helps soften the fibres so they can settle back into place. For synthetic rugs, always use a low heat setting to avoid damage.

If you’d prefer not to use heat, water alone can also help. Lightly mist the area with a spray bottle (avoiding soaking), then gently lift and separate the fibres with your fingers or a wide-tooth comb. As the rug dries naturally, the wrinkles should ease.

How to Get Wrinkles Out of a Rug After Cleaning

It’s common for a rug to look buckled after washing, especially while it’s still damp. In many cases, the wrinkles will disappear once the rug has fully dried.

To help the rug dry flat:

• Lay it on a clean, hard surface rather than carpet.
• Allow it to air dry naturally for at least 24 hours.
• Avoid heaters or hair dryers, which can cause uneven drying.

If wrinkles remain once dry, leftover cleaning product may be preventing the rug from settling. Rewashing until the water runs clear, followed by careful drying, can help restore its shape.

How to Stop Rug Corners and Edges From Curling

Curling corners and edges are some of the most common issues when learning how to flatten a rug. This can happen with both new and older rugs.

Lightly dampen the curled area, gently bend it in the opposite direction and leave it to dry fully over a day or so. For stubborn areas, placing a heavy object such as books or furniture on top can help encourage the rug to settle.

If your rug continues to lift, an anti-slip rug underlay is particularly helpful, especially if you’re trying to work out how to get a rug to lay flat on new carpet. An underlay adds grip, reduces movement and helps the rug sit more smoothly.

How to Straighten a Rug or Runner

Runner rugs can sometimes appear kinked or slightly uneven, particularly longer or handmade styles. This is often due to the weaving process or fibres stretching over time.

In some cases, washing the rug (if the care label allows) can help the fibres reset. Always let the rug dry fully before reassessing, as damp rugs often appear more distorted than they are.

How to Flatten a New Rug

If you’ve just unpacked a rug and it won’t lie flat, you’re not alone. Knowing how to flatten a new rug often comes down to patience.

To help a new rug settle:

• Roll it tightly in the opposite direction for up to two days, then lay it flat.
• Leave it flat on a hard surface for 48 hours to allow fibres to relax.
• Use gentle steam or light misting if creases remain.
• Place it on top of a rug underlay mat.

Most new rugs will flatten naturally with time as the fibres adjust.

How to Make a Rug Lay Flat on Carpet

Getting a rug to lie flat on carpet can be more challenging than on hard flooring. The softness of carpet can cause rugs to shift, ripple or lift at the edges, especially if the rug is lightweight or has recently been rolled.

One of the most effective ways to make a rug lay flat on carpet is by using a rug underlay. A carpet-to-carpet underlay is designed to grip both surfaces, helping to reduce movement and encouraging the rug to sit more evenly. It can also improve comfort and help prevent trips by keeping edges in place.

There are a few additional tips that can help your rug settle:

• Give the rug time to relax after unrolling, as fibres often flatten naturally
• Place furniture partially on the rug to add gentle weight and hold it in position
• Reverse-roll the rug for a short period if it keeps curling back on itself
• Use light steam or misting on raised areas to help relax stubborn fibres

If your carpet is particularly thick or plush, it may take a little longer for the rug to fully settle. With the right underlay and a bit of patience, most rugs will begin to lie flatter and feel more secure on carpeted floors.

How to Flatten an Outdoor Rug That’s Curling

Outdoor rugs are often made from synthetic fibres such as polypropylene, chosen for durability and weather resistance. These rugs can curl more easily and are sensitive to heat.

Start with reverse-rolling or placing weight on curled areas. If you use steam, keep settings low and always protect the rug with a damp cloth to avoid damage.
