So you just purchased a carpet and noticed it has creases...
Don't fret! Due to the organic nature of your carpet's pile, there's a good chance these creases will come out through your use and enjoyment. If a carpet has a crease or "lumpiness" give the carpet several weeks to settle. Often a good steaming or application of heavy weighted objects will help release any stress or creases the rug has.
Here are 4 Great, Easy and Quick Ways to get the Creases and Fold Marks out of your rug! Use any single one, or a combination of several!
1. Back-roll or reverse roll the carpet. This is the easiest way to deal with a carpet that does not sit flat. Fold the rug in the opposite direction it curls or creases. Be careful as you do it because you'll want to listen for cracking noises: if you hear them, stop immediately
2. Place heavy furniture or weight on the carpet. This should accelerate the settling time at least two fold.
3. Wait for the rug to settle on it's own: allow the rug to sit open for several weeks and it should naturally release tension from a hard roll or fold.
4. Place the rug outdoors under the sun in temperatures between 70-85 degrees fahrenheit. Direct sunlight for several hours should help the rug release tension naturally and at the very least make it more supple for reverse-rolling as noted in suggestion 1.
As a last resort...
Plan B. Have the carpet steamed. Have this done at your local rug retail store by a professional, not with in home services. A rug expert will be able to quickly assess the severity of the problem such as simply having been folded too long (no big deal) to an inconsistent tension within the structure of the rug (very rare) which will not be easily remedied.
The rug below had just recently been opened from an extended period of time in storage (approximately ten years.) The rug is showing classic symptoms of having been barrel rolled: a method of folding and rolling to make them more compact for easier handling. These folds will release over time, however as you will see, there are ways to accelerate this process.
As seen below, we placed these rolled rugs on top of some plywood to distribute the weight and accelerate the settling process. If you give the rug some time, it should rest flat on its own, however adding weight may reduce the settling time in half. In the case of this rug, it took about 10 days of added weight as opposed to an estimated 3 weeks of regular use and vacuuming.
In general, if you have allowed the carpet good time to settle, there may be a more serious problem. If problems with creases, buckles or lumps persist, there may be serious structural issues with too much or not enough tension within the skeleton of the rug which can be seen below. Tension within the rug in some cases be released by a professional. This process is done by creating a small bed of nails approximately the size of the rug. The rug is then made damp, stretched onto the bed, and left to dry. If there is a significant amount of squaring needed, starch may be added to the back of the rug to reinforce rigidity in the rug.
