When applying gold leaf, choosing the right adhesive is crucial for a flawless finish. Gilding adhesive—also known as gold leaf size—is specifically designed for this purpose, ensuring the leaf adheres smoothly and securely to various surfaces. Here’s a guide to selecting the best adhesive for gold leaf application.
What is the Best Adhesive for Gold Leaf?
For gold leaf application, the best adhesive is water-based or oil-based gilding size. These adhesives are formulated to create a tacky surface that holds the delicate gold leaf in place. Water-based size is ideal for interior projects and offers a quicker drying time, while oil-based size is suitable for both indoor and outdoor use, providing a longer open time for application.
How to Choose Between Water-Based and Oil-Based Gilding Size?
| Feature | Water-Based Size | Oil-Based Size |
|---|---|---|
| Drying Time | 30 minutes to 1 hour | 12 to 24 hours |
| Durability | Best for interiors | Suitable for exteriors |
| Clean-Up | Easy with soap and water | Requires solvents |
| Finish | Matte to satin | Glossy |
| Application | Quick projects | Detailed work |
When to Use Water-Based Gilding Size?
- Quick Projects: Water-based size dries faster, making it perfect for small or urgent projects.
- Easy Clean-Up: It can be cleaned with soap and water, making it user-friendly.
- Interior Use: Ideal for indoor applications where environmental conditions are stable.
When to Use Oil-Based Gilding Size?
- Extended Working Time: Oil-based size offers a longer open time, allowing for meticulous placement of gold leaf.
- Outdoor Durability: It’s more durable for exterior projects, resisting environmental factors better.
- Rich Finish: Provides a glossy finish that enhances the appearance of gold leaf.
How to Apply Gold Leaf Using Gilding Size?
- Prepare the Surface: Ensure the surface is clean, dry, and smooth.
- Apply the Size: Use a brush to apply a thin, even coat of the gilding size.
- Wait for Tackiness: Allow the size to become tacky. This varies by type—usually 30 minutes for water-based and up to 24 hours for oil-based.
- Apply Gold Leaf: Carefully lay the gold leaf over the tacky size, gently pressing it down.
- Smooth Out: Use a soft brush to smooth the leaf and remove any excess.
Tips for Successful Gold Leaf Application
- Avoid Drafts: Work in a draft-free area to prevent the delicate gold leaf from tearing.
- Use a Soft Brush: A soft, natural bristle brush helps in smoothing the leaf without damage.
- Practice Patience: Allow the gilding size to reach the perfect tackiness for optimal adhesion.
