How to Seal Diamond Painting with Glue?

Diamond painting has become a widely popular craft and art form that allows enthusiasts to create stunning and shimmering masterpieces using tiny resin diamonds. These paintings, once completed, are cherished for their intricate designs and sparkling beauty. 

To ensure that your diamond painting remains intact and beautiful for years to come, it is essential to seal it properly. In this guide, we will explore how to seal diamond painting with glue, a reliable and effective method that preserves the brilliance of the diamonds while securing them in place.

Why Seal Diamond Painting with Glue?

Sealing diamond paintings with glue serves multiple purposes, making it an attractive choice for preserving the artwork. Firstly, it provides a protective layer that prevents the diamonds from dislodging or falling off the canvas. 

Additionally, the glue acts as a sealant, locking the diamonds in place and reducing the risk of dust and dirt accumulation. Unlike some spray sealers, glue penetrates the gaps between diamonds, ensuring a more secure and durable bond.

Choosing the Right Glue

Selecting the appropriate glue is crucial to achieve the best results when sealing diamond paintings. It is essential to choose a glue that dries clear and does not leave any visible residue on the canvas. 

A popular choice among diamond painting enthusiasts is DecoArt’s Triple Thick Glaze, known for its transparency and strong adhesive properties. Other craft glues, such as Mod Podge, can also be used, but it is essential to ensure they are compatible with the canvas material and diamonds.

Preparation and Setup

Before beginning the sealing process, it is essential to prepare the diamond painting and the work area. Start by gently cleaning the canvas surface with a soft cloth to remove any dust or debris. 

It is advisable to work on a clean and flat surface to avoid accidental spills or damage during the sealing process. Gather all the necessary materials, including the selected glue, a brush or applicator, and a clean cloth for any spills.

Step-by-Step Guide: How to Seal Diamond Painting with Glue

  • Setting Up Your Work Area Begin by finding a clean and flat surface to work on. This could be a table or a large board covered with a soft cloth to prevent scratching the canvas. Organize your diamond painting kit and glue within reach for easy access.
  • Applying the Glue Dip the brush or applicator into the glue and start applying it evenly over the entire diamond painting surface. Ensure that each diamond is coated with a thin layer of glue, ensuring they are securely adhered to the canvas.
  • Drying Process Allow the glue to dry thoroughly before moving or framing the diamond painting. 
  • The drying time may vary depending on the type of glue used, but it is generally recommended to let it dry overnight for optimal results.
  • Evaluating the Results Once the glue has dried, carefully examine the diamond painting for any missed areas or uneven application. If you find any spots that need additional sealing, apply a small amount of glue and let it dry again.
  • Alternative Glue Sealers While DecoArt’s Triple Thick Glaze and Mod Podge are popular choices, there are other glue sealers available that can provide different effects. Some crafters prefer using glitter-infused glue for added sparkle, while others opt for matte sealers to reduce shine.

Tips and Tricks for a Perfect Seal

  • Use a soft brush or applicator to avoid damaging the diamonds or canvas.
  • Apply the glue in a well-ventilated area to avoid inhaling fumes.
  • Practice on a small section before sealing the entire painting to get comfortable with the process.
  • Avoid excessive glue application to prevent smudging or clumping.


Sealing a diamond painting with glue is a simple yet effective way to preserve its beauty and ensure it lasts for years to come. The process requires careful preparation, even application, and patience during the drying phase. With the right glue and proper technique, you can confidently seal your diamond painting, allowing it to shine brightly and become a cherished piece of art. So, gather your materials, follow the steps outlined in this guide, and seal your diamond painting to enjoy its brilliance and charm for a lifetime. Happy crafting!
