Applying gold leaf can be a delicate process that requires the right adhesive to ensure a smooth and long-lasting finish. The most commonly used adhesive for gold leaf application is gilding adhesive, also known as size. This specialized glue is designed to hold the thin sheets of gold leaf securely in place on various surfaces.
What is the Best Glue for Gold Leaf?
When it comes to adhering gold leaf, the preferred choice is water-based or oil-based gilding size. Each type has its specific applications and drying times:
- Water-Based Size: Quick-drying and easy to clean up with water, making it ideal for indoor projects and beginners.
- Oil-Based Size: Offers a longer open time, allowing for more precise application, and is suitable for outdoor use due to its durability.
Both types of size are designed to remain tacky after drying, providing the perfect surface for the delicate gold leaf to adhere to.
How to Choose Between Water-Based and Oil-Based Size?
Choosing the right size depends on your project requirements:
| Feature | Water-Based Size | Oil-Based Size |
|---|---|---|
| Drying Time | 15-30 minutes | 1-3 hours |
| Cleanup | Soap and water | Mineral spirits |
| Durability | Indoor use | Suitable for outdoor use |
| Working Time | Short (ideal for quick work) | Longer (more time to adjust) |
When to Use Water-Based Size?
Water-based size is perfect for projects where a quick setup is beneficial. It is especially useful for beginners due to its ease of use and cleanup. Common applications include:
- Indoor Decorative Items: Picture frames, sculptures, and small furniture pieces.
- Craft Projects: Ideal for DIY enthusiasts wanting to experiment with gold leaf.
When to Use Oil-Based Size?
Oil-based size is better suited for projects requiring more time and durability. It is often used by professionals for:
- Outdoor Applications: Signs, architectural details, and garden ornaments.
- Larger Projects: Murals or extensive gilding work that requires a longer working time.
How to Apply Gold Leaf with Size?
Applying gold leaf involves several steps to ensure a smooth and professional finish:
- Prepare the Surface: Clean and smooth the surface to remove dust and imperfections.
- Apply the Size: Use a brush to apply an even coat of size. For water-based size, wait until it becomes tacky (about 15-30 minutes). For oil-based size, wait 1-3 hours.
- Lay the Gold Leaf: Carefully place the gold leaf onto the tacky surface. Use a soft brush to gently press it down and smooth out any wrinkles.
- Seal the Gold Leaf: Once applied, seal the gold leaf with a protective varnish to enhance durability and shine.
What are Common Mistakes to Avoid?
When working with gold leaf, there are a few common pitfalls to watch out for:
- Applying Size Too Thickly: This can lead to uneven drying and a poor finish.
- Rushing the Process: Ensure the size is appropriately tacky before applying the leaf.
- Skipping Sealing: Failing to seal can result in tarnishing or damage to the gold leaf.

How Do You Remove Excess Gold Leaf?
Excess gold leaf can be gently brushed away with a soft brush. Ensure the adhesive is dry to avoid disturbing the adhered leaf.
Can You Use Regular Glue for Gold Leaf?
Regular glue is not recommended as it lacks the tacky quality needed for proper adhesion. Gilding size is specifically formulated for this purpose.
How Long Does Gold Leaf Last?
With proper application and sealing, gold leaf can last for many years, especially when protected from environmental factors.
Is Gold Leaf Waterproof?
Gold leaf itself is not waterproof, but applying a sealant can protect it from moisture and tarnishing.
Can You Apply Gold Leaf to Any Surface?
Gold leaf can be applied to a variety of surfaces, including wood, metal, glass, and even some fabrics, as long as the surface is properly prepared.
