Diamond Painting – How to Seal with Resin?

Diamond painting has become a widely popular craft and hobby, offering a meditative and creative outlet for enthusiasts. As you invest time and effort into completing a diamond painting, it’s essential to protect and preserve your masterpiece for years to come. One effective method of sealing and safeguarding your finished diamond painting is through resin sealing. In this article, we’ll guide you through the process of resin sealing, ensuring your artwork remains intact and stunning.

Understanding Resin Sealing

Resin sealing involves applying a protective layer of resin over the completed diamond painting. Resin, once cured, creates a clear and glossy surface that enhances the sparkle of the diamonds and adds a professional touch to the artwork. The benefits of resin sealing include increased durability, protection against dust and moisture, and the elimination of the need for framing.


Before you begin the resin sealing process, gather all the necessary materials, including a high-quality epoxy resin, mixing cups, stirring sticks, a heat gun or torch, and a clean, flat workspace. Ensure the diamond painting is free from dust and debris before proceeding.

Step-by-Step Guide

  • Properly laying out the completed diamond painting: Carefully place the diamond painting on a flat surface, ensuring it’s free from wrinkles or creases.
  • Mixing and preparing the resin: Follow the instructions on the resin packaging to mix the epoxy resin thoroughly. Be sure to wear appropriate protective gear, such as gloves and a mask, when handling the resin.
  • Applying the resin to the diamond painting: Using a brush or spatula, apply an even layer of resin over the entire surface of the diamond painting. Work in small sections to ensure uniform coverage.
  • Ensuring even distribution and coverage: Use the brush or spatula to spread the resin evenly, ensuring that it reaches all corners and crevices of the artwork.
  • Removing air bubbles and smoothening the surface: To eliminate air bubbles, gently run a heat gun or torch over the resin-coated surface. 
  • This process will also help in smoothening out any imperfections.

Drying and Curing

Allow the resin-sealed diamond painting to dry and cure for the recommended time as specified on the resin product’s packaging. Avoid moving or touching the artwork during this time to prevent any disturbances.

Finishing Touches

Once the resin is fully cured, trim any excess resin from the edges using a sharp knife or blade. Wipe the surface clean to achieve a polished finish that showcases the brilliance of the diamonds.

Precautions and Tips

  • Always work in a well-ventilated area when using resin.
  • Avoid direct contact with the resin, as it can cause skin irritation.
  • Mix the resin thoroughly and avoid over-mixing to minimize the formation of air bubbles.
  • Use a heat gun or torch carefully to prevent overheating or scorching the resin.

Comparing Resin Sealing to Other Methods

Resin sealing offers several advantages over traditional framing or other sealants. It provides a seamless and clear protective layer that allows the diamonds to sparkle brightly without the hindrance of a frame. Additionally, resin sealing is more durable, ensuring your diamond painting stays intact for an extended period.

Long-Term Maintenance

To ensure the longevity of your resin-sealed diamond painting, avoid exposing it to direct sunlight for extended periods. Clean the surface gently with a soft, lint-free cloth to remove any dust or fingerprints.


Resin sealing is an excellent method to preserve and protect your completed diamond painting, enhancing its beauty and longevity. By following the step-by-step guide and taking necessary precautions, you can achieve a stunning and durable resin-sealed artwork that will be cherished for years to come. So, unleash your creativity and enjoy the process of sealing your diamond paintings with resin.
