How Much Sealer Do You Need?
Based on supplier recommendations, one bottle of sealer covers approximately a 40x50 cm (16x20 inches) canvas. Ensure you have enough sealer to cover your entire artwork adequately.
Steps to Apply Sealer to Your Diamond Painting
Prepare the Area
- As a safety precaution, keep pets and children away from the workspace during the sealing process.
Secure the Diamonds
- Ensure all diamonds are properly set by applying gentle pressure using a rolling pin or a similar tool.
- Place a clean cloth or an old t-shirt over the canvas to prevent scratching or damaging the diamonds while rolling.

Shake the Sealer
- Before application, shake the bottle of sealer thoroughly to ensure an even consistency.
Apply a Thin Layer of Sealer
- Using a soft-bristled brush, apply a very thin layer of sealer evenly over the entire painting.
- Avoid applying too much sealer, as this can cause stickiness and dull the sparkle of the diamonds.
Allow the Sealer to Dry
- Let the sealer dry completely for at least 72 hours in a dust-free environment.
- Ensure the painting remains flat and undisturbed during the drying process.
Troubleshooting Common Issues
Sticky Surface After Drying
- If the painting feels sticky after drying, it may be due to applying too much sealer or insufficient drying time.
- To remedy this, gently wipe the surface with a damp cloth or baby wipe to remove any tackiness.
Additional Tips
Framing Without Sealing
- If you plan to frame your diamond painting under glass, sealing is not necessary. The glass will protect the diamonds and keep them in place.
