How to Get Wrinkles Out of a Diamond Painting Canvas: A Complete Guide


Diamond painting is a popular DIY craft that combines the art of painting by numbers with the sparkle and shine of mosaic art. It's a therapeutic and enjoyable activity that allows you to create stunning works of art using tiny resin diamonds. However, when your diamond painting kit arrives, you may find that the canvas is wrinkled and not laying flat. In this guide, we will explore various methods to get rid of wrinkles and creases on your diamond painting canvas, ensuring a smooth and flawless surface for your masterpiece.


Understanding the Causes of Wrinkles in Diamond Painting Canvases

Before we delve into the techniques to remove wrinkles, let's understand why diamond painting canvases often arrive with creases. Diamond painting canvases are typically rolled up for shipping purposes, which can lead to the formation of wrinkles and creases on the surface. Additionally, the adhesive used on the canvas, whether it's double-sided tape or poured glue, can also contribute to the development of wrinkles. It's important to note that these wrinkles do not affect the final result of your diamond painting and can be easily smoothed out.

Method 1: Unrolling and Re-rolling the Canvas

The simplest and most effective method to remove wrinkles from a diamond painting canvas is to unroll it and re-roll it in the opposite direction. Start by carefully unrolling the canvas and laying it on a flat surface. Then, roll it back up, but this time, roll it in the opposite direction. Repeat this process a few times, alternating between rolling with the printed side out and the blank side out. This method helps to reduce the curling of the canvas and smooth out any wrinkles.

Method 2: Using Heavy Objects to Flatten the Canvas

Another effective method to flatten a diamond painting canvas is by using heavy objects to apply pressure. Start by placing the canvas on a flat surface and ensuring it is smooth and straight. Then, place heavy objects such as books or a heavy board on all four sides of the canvas to hold it down. Make sure the objects are evenly distributed to apply even pressure throughout the canvas. Leave the canvas under the heavy objects for a few hours or overnight. This method helps to flatten the canvas and eliminate wrinkles.

Method 3: Using Heat to Remove Wrinkles

Heat can be a useful tool in removing wrinkles from a diamond painting canvas, but it must be used with caution to avoid damaging the canvas or the adhesive. Here are two methods that utilize heat:

Method 3.1: Ironing the Canvas

Ironing is a common method used to remove wrinkles from fabric, including diamond painting canvases. However, it's important to set the iron to a low heat setting to avoid melting the adhesive or damaging the canvas. Here's how to do it:

  1. Lay the diamond painting canvas on a flat surface.
  2. Cover the canvas with a thin cloth or towel to protect it from direct heat.
  3. Set the iron to a low heat setting and gently iron the cloth-covered canvas, focusing on the areas with wrinkles.
  4. Keep the iron moving to prevent overheating any particular spot.
  5. Check the canvas frequently to ensure it is not getting too hot or damaged.
  6. Repeat the process as needed until the wrinkles are smoothed out.

Method 3.2: Using a Heating Pad

If you're concerned about using an iron, a heating pad can be a safer alternative. Here's how to use a heating pad to remove wrinkles from a diamond painting canvas:

  1. Lay a towel on a flat surface.
  2. Place the heating pad on a low to medium heat setting on top of the towel.
  3. Lay the diamond painting canvas on top of the towel, with the wrinkled side facing up.
  4. Cover the canvas with another towel or cloth.
  5. Leave the canvas on the heating pad for 10-15 minutes, periodically checking to ensure it is not getting too hot.
  6. Remove the canvas from the heating pad and gently smooth out any remaining wrinkles with your hands.

Method 4: Using a Wrinkle Release Spray

Wrinkle release sprays are designed to remove wrinkles from fabric, and they can also be used on diamond painting canvases. Before using a wrinkle release spray, perform a patch test on a small, inconspicuous area of the canvas to ensure it does not cause any damage or bleeding of the ink. Here's how to use a wrinkle release spray:

  1. Lay the diamond painting canvas on a flat surface.
  2. Hold the wrinkle release spray bottle 6-8 inches away from the canvas.
  3. Spray a light, even mist of the wrinkle release spray on the backside of the canvas, focusing on the areas with wrinkles.
  4. Avoid saturating the canvas with the spray.
  5. Use a tissue or cloth to gently dab any excess spray and smooth out the canvas with your hands.
  6. Allow the canvas to air dry completely before starting your diamond painting.


Wrinkles on a diamond painting canvas may be an initial frustration, but they can be easily remedied with the right techniques. Whether you choose to unroll and re-roll the canvas, use heavy objects, apply heat, or utilize a wrinkle release spray, these methods will help you achieve a smooth and wrinkle-free surface for your diamond painting masterpiece. Remember to always handle the canvas with care to avoid damaging the adhesive or the printed design. Now, you can confidently embark on your diamond painting journey and enjoy the process of creating beautiful, sparkling artwork. Happy painting!
