Seal Your Diamond Painting, Keep The Sparkle Forever

how to seal a diamond painting without losing sparkle

Diamond painting is a unique and delightful craft that requires careful care to maintain its original brilliance and atmosphere. Sealing is an important step to protect diamond paintings from the external environment, improve their overall quality and longevity, and prevent the loss of sparkle. This process involves applying a clear, protective coating to the surface of the diamond painting to protect it from dust, moisture, and other external factors. The sealing material should be chosen carefully to ensure the diamond painting retains its brilliance, and it should be applied in a thin, even layer using a soft-bristled brush or a spray sealer.

Sealing materials: Minwax, Mod Podge, Deco Art Triple Thick, and more

Sealing a diamond painting is necessary for lower-quality kits or non-Diamond Art Club products. This is due to poor quality, popping drills, loss of stickiness, or if you choose not to frame your piece. Sealing materials include Minwax, Mod Podge, and Deco Art Triple Thick, among others.

Minwax

Minwax Polycrylic Clear Gloss is a top-notch sealing choice that outperforms alternatives like Mod Podge, which tend to yellow over time. Unlike other products that can alter the artwork's appearance, Minwax maintains the original beauty without yellowing or cracking. It is not too stiff to roll up for storage. The brush-on version is preferable for diamond art as it reaches between the drills, unlike the spray version. Before sealing, ensure that the drills are firmly set using heat and a soft rubber brayer. Use a medium-stiff brush to apply Minwax in light, short strokes, covering the canvas with a thin coat.

Mod Podge

Mod Podge is a popular choice for sealing diamond paintings, but it can dull the sparkle of the diamonds. It is recommended to water it down a bit and clean the top of the diamonds afterward. Some users have experienced a loss of sparkle after using Mod Podge, but it is still a viable option for sealing diamond paintings.

Deco Art Triple Thick

Deco Art Triple Thick Gloss is a high-gloss varnish that delivers a diamond-clear finish in just one coat. It is a non-toxic, water-based varnish that creates a glass-like protective finish, intensifying the depth of colors. It dries quickly, does not crack or yellow, and is weather-resistant and heat-resistant. It is a popular choice among diamond painters as it seals the diamonds with a brilliant finish while maintaining the shine from the gems.

Application: brush-on vs spray-on sealers

Brush-on sealers are applied with a brush and can reach between the drills, unlike spray-on sealers. They are an all-in-one solution, acting as a glue, sealer, and finish. They are water-resistant, which is ideal if you plan to mount your diamond painting on a foam board or frame it without glass. However, one drawback is that some shine will be lost after sealing, and you won't be able to roll up your paintings. DecoArt's Triple Thick Glaze is a popular choice, as it has the perfect consistency, makes the canvas firm, and retains as much sparkle as possible. Another option is the classic Mod Podge, which is a cheaper alternative. It is important to note that Mod Podge Glitter reduces the shininess of the diamonds and replaces it with micro-fine glitter.

On the other hand, spray-on sealers coat the finished diamond painting in a crystal-clear finish. They are easy to apply, non-toxic, and come in different finishes and formulas. For example, Mod Podge offers a Super Gloss variety to preserve the shininess and a Matte Gloss variety for a less shiny finish. Spray-on sealers are waterproof, non-yellowing, and quick-drying. Additionally, you can still roll up your canvas after applying a spray-on sealer. However, they do not function as a glue, so they won't fill the gaps between the diamonds.

Both brush-on and spray-on sealers have their advantages and disadvantages. When choosing between the two, consider factors such as ease of application, the level of shine desired, the need for water resistance, and whether you want to roll up your painting afterward.

Some popular brush-on sealers include:

  • DecoArt Triple Thick
  • Mod Podge (classic, Super Gloss, and Matte Gloss)
  • Minwax Polycrylic Clear Gloss
  • Aquamono glue from Tombow

Some popular spray-on sealers include:

  • Mod Podge Spray Acrylic Sealer
  • Aleene's Super Gloss Finish Acrylic Sealer

Pros and cons of brush-on sealers

Brush-on sealers offer a more precise and controlled application compared to spray-on sealants, making them ideal for targeting specific diamonds or areas of the painting. They dry clear, preserving the colours and sparkle of the diamonds. However, brush-on sealers may require careful application to avoid excess sealant or brush strokes, and they typically have longer drying times than spray-on alternatives.

Brush-on sealers come in a variety of finishes and consistencies, allowing users to choose based on their personal preferences. Some products function as an all-in-one glue, sealer, and finish, and are water-resistant, making them suitable for mounting on foam boards or framing without glass. However, a potential drawback of brush-on sealers is that they may cause a slight loss of shine in the diamonds. Additionally, paintings sealed with brush-on sealers cannot be rolled up, limiting storage and display options.

When selecting a brush for brush-on sealers, a brush with medium-stiff "Black China boar" bristles is recommended. Before application, dip the brush about 2 inches into the sealant, allowing any excess to drip off. Apply the sealant in light, short strokes, covering the canvas with a thin coat. Ensure that the sealant reaches between the drills, especially for round drilled canvases.

While brush-on sealers offer precision and protection, they may not be suitable for all diamond painting projects due to the potential for shine reduction and the inability to roll up the final product. It is essential to test the sealant on a small area first to ensure it dries clear and does not affect the colours or sparkle of the diamonds.

Pros and cons of spray-on sealers

Sealing a diamond painting is an important step to protect the diamonds from falling out and making the colours pop. Spray-on sealers are an option for sealing diamond paintings, and they have both advantages and disadvantages.

Pros of Spray-On Sealers

  • Spray-on sealers are a quick and easy way to seal a diamond painting. They can be applied by shaking the can well and then spraying the canvas in a side-to-side motion until it is covered in a glossy finish.
  • Spray-on sealers can provide a thin, even layer of protection, which is ideal for diamond paintings as it reaches between the drills.
  • Spray-on sealers can protect the diamond painting from dust, moisture, and other external factors, extending its life.
  • Spray-on sealers can enhance the colour and contrast of diamond paintings, making them more vivid and attractive.
  • Spray-on sealers can improve the details of the diamond painting, making the sparkle of each diamond more obvious.

Cons of Spray-On Sealers

  • Some spray-on sealers may not be suitable for certain types of drills. For example, some sealers may melt the facets off crystal drills, turning them into smooth domes of plastic.
  • Spray-on sealers may not always provide a strong enough seal, as some users have reported that their diamond paintings still felt tacky after using a spray-on sealer.
  • Spray-on sealers may not be as precise as brush-on sealers, and may require multiple coats to achieve the desired level of protection.
  • Spray-on sealers may not be suitable for all working environments, as they require a well-ventilated and moderate temperature space to dry and cure properly.

Overall, spray-on sealers can be a convenient and effective way to seal a diamond painting, but it is important to consider the potential drawbacks and choose a sealer that is suitable for the specific type of drills and working conditions.

Step-by-step sealing process

Sealing a diamond painting is an important step to ensure its longevity and protect it from dust, moisture, and other external factors. Here is a step-by-step guide to sealing your diamond painting without losing its sparkle:

Step 1: Prepare the Materials

Gather all the tools and materials you need, such as the sealing product, a paintbrush, a soft-bristled brush or toothbrush, tweezers, and a damp microfiber cloth if needed.

Step 2: Clean the Diamond Painting

Use a soft-bristled brush or toothbrush to gently remove any residual wax, glue, or debris between the diamonds. If the canvas has been exposed to dust, use a damp microfiber cloth to carefully clean the tops of the drills. Ensure that all diamonds are firmly in place and use tweezers to adjust any loose diamonds.

Step 3: Choose a Sealing Material

Select a sealing material that will retain the sparkle of your diamond painting. Popular options include Minwax Polycrylic Clear Gloss, Deco Art Triple Thick, and Mod Podge. Avoid sealants with glitter if you want to maintain the original sparkle of your diamonds.

Step 4: Apply the Sealing Material

Follow the instructions on the sealing product you have chosen. If using a brush-on sealer, dip the brush into the sealant, allowing any excess to drip off. Apply the sealant in light, short strokes, covering the canvas with a thin, even coat. Ensure you get the sealant between the drills, especially for round-drilled canvases. If using a spray-on sealer, shake the can well and spray the canvas in a side-to-side motion until it is evenly coated.

Step 5: Allow the Sealing Material to Dry

Place your painting on a flat surface in a well-ventilated, dust-free environment. Allow the sealant to dry completely, following the instructions on the specific product you have chosen. Typically, it is recommended to let the painting dry overnight or for at least 24 hours, and up to 48 hours for the best results.

By following these steps, you can effectively seal your diamond painting, protecting it from external factors and ensuring that it retains its sparkle and shine.
