Glue for Gold Leaf: What You Need to Know

We know choosing the right glue is essential when it comes to gilding. Whether you’re working on fine art, antique restoration, or decorative interior design, the adhesive—often referred to as “gilding size”—is what allows your gold leaf to adhere properly and achieve that iconic radiant finish.

In this article, we’ll walk you through the key types of glue used for gold leaf, what makes them suitable (or not), and what to consider before you begin your gilding project.

Glue for Gold Leaf: Understanding Your Options

Gold leaf is an extremely delicate material, and unlike other metallic finishes, it must be applied using purpose-made glues that are formulated to work with fine sheets of metal. We supply a carefully curated range of glue for gold leaf that have stood the test of time among traditional gilders and professional restorers alike.

Let’s explore some of the most popular glue for gold leaf options and their specific uses.

Isinglass – A Traditional Choice for Restoration

Isinglass is a natural glue for gold leaf made from the dried swim bladders of sturgeon fish. Once prepared, it becomes a clear, flexible glue for gold leaf—especially on delicate surfaces such as paper, vellum, or old wooden substrates.

We stock high-quality Isinglass because of its reliability in fine art and conservation settings. Its gentle nature makes it perfect for intricate or antique work where minimal interference with the original surface is key. Many conservators choose Isinglass when precision and minimal colour shift are essential.

Rabbit Skin Glue – Ideal for Gesso and Base Preparation

Rabbit Skin Glue is one of the oldest and most reliable adhesives used in traditional gilding. While it is not typically used as the primary glue for gold leaf, it plays a vital role in surface preparation.

This glue is commonly used in the making of gesso—a mixture of glue and chalk that forms the base layer on wood panels and frames. A well-prepared gesso base helps ensure that gold leaf adheres smoothly and durably. Rabbit Skin Glue offers strong adhesion to porous surfaces and is easy to work with when mixed and heated correctly. We offer both granulated and ready-prepared options to suit different workshop setups.

Chipping Glue

Chipping Glue is available in our store, however it’s important to clarify this adhesive is not typically a glue for gold leaf. Instead, Chipping Glue is used in a decorative process called glue-chipping, which creates frosted or “chipped” effects on glass. The glue causes the surface of the glass to contract and flake in a decorative pattern. While gold leaf may be added to the glass after this process for visual enhancement, Chipping Glue itself is not designed to be a glue for gold leaf and should not be used as a replacement for traditional gilding size.

How to Choose the Right Glue for Gold Leaf for Your Project

Choosing the right glue for gold leaf depends on several key factors:

• Surface Material: For wood, plaster, or canvas, traditional glues like Isinglass or Rabbit Skin Glue (as part of a gesso base) are ideal.
• Type of Gold Leaf: Genuine gold leaf tends to be more forgiving, whereas imitation leaf (like Dutch metal) often requires specific glue for gold leaf due to its weight and tendency to tarnish. If you’re unsure, our team can advise you on compatible adhesives for each leaf type.
• Environmental Considerations: Humidity and temperature can affect glue drying times. Traditional glues like Isinglass are sensitive to environmental changes, while some modern gilding sizes offer longer open times and increased stability.
• Application Method: Brush application is the most common, but some glue for gold leaf can be thinned for spray use. Always test your method on a sample board before committing to a large surface.

The Importance of Surface Preparation

Before applying any glue for gold leaf, surface preparation is essential. A poorly prepared surface can cause the leaf to lift or flake over time. For traditional water gilding, begin with a smooth base layer of gesso (made from Rabbit Skin Glue and whiting). This base should be applied in multiple thin coats and sanded to a smooth, glass-like finish.

For paper, bookbinding, or conservation work, surfaces may require a size that is both flexible and non-reactive—this is where Isinglass really excels.

Clean, dry surfaces free from oils or dust are always a must. Once your glue for gold leaf has reached the appropriate level of tack—whether it’s a water size or a more modern solution—you’re ready to apply the leaf.
