How to Seal Diamond Painting Like a Pro?

We know that completing a painting is a little bit long task and can take up to a month. By the way, it depends on your speed and the size of the painting. After the completion of your painting, you must be thinking about how to seal diamond painting?

Don’t worry we are here to help you with a step-by-step guide to sealing a diamond painting.

Our Canvas is made with high-quality materials and has super adhesive glue on it but still, we recommend you use a diamond painting sealer. Because sealing will make an extra protection layer on your artwork.

Watch the below video to look at the sealing process, or if you want to read a step-by-step process, please continue reading this post.

We want you to invest in diamond paintings, not in the sealing process. So to make the sealing process as cheapest as possible we are using an old paintbrush to apply the mod podge on the canvas.

You just need to invest less than $10 and your diamond painting sealing will be done.

Types of diamond Painting Sealers

There are two types of sealant

  1. Brush on sealers
  2. Sprays sealers

Let’s have a look at the sealers that can be applied through brushes

Brush-On Sealer

Brush-on sealers are the best sealant to prevent your diamond painting from any type of damage and this will definitely increase the life span of your diamond painting. You can choose a shiny or matt finish brush on the sealer.


  • Water-resistant
  • Can be used for other things like wood sealing as well
  • Dust Proof
  • You can mount your Painting without the Glass Frame


  • Your diamonds will lose some shine after sealing
  • You won’t be able to roll up your painting

Spray Sealers

A spray sealer is totally different from a Brush-on sealer. These are used to give a crystal clear and shiny finish to the diamond painting. But it didn’t fill the space between the diamonds like the brush-on sealers.


  • This helps you to make your diamond sparkle for a long time.
  • Waterproof
  • Dries Quickly
  • You can roll up the finished canvas


  • Gaps between the Diamonds will not be filled
  • Less dust resistant

What type of sealer should you choose?

This is totally a personal choice. But if you want to know our opinion, we would highly recommend you to get a spray-on sealer.

We love diamond painting because it shimmers, if we apply a thick layer of mod podge on the diamond painting it will lose its shining. So we suggest you always use a spray-on sealer.
