Built to Last — Indoors and Outdoors
One of the key advantages of genuine gold leaf is its longevity.
- Does not oxidize
- Withstands weather conditions
- Maintains color and brilliance over time
This makes it suitable for both interior restoration and exterior architectural work, including domes, statues, and signage.
Exterior
- Must use 23k–23.5k genuine gold leaf minimum
- Oil-based sizing system
- No burnishing
- Substrate stability critical
- Designed for UV and moisture exposure
Lower karat gold increases risk of tarnish.
Interior
- 22k–24k genuine gold leaf depending on specification
- Oil gilding or water gilding possible
- Burnishing achievable with water gilding

Oil Gilding vs Water Gilding
Karat Selection Guide
Choosing the Right Gold Leaf for Your Project
Karat Selection
- 22k–24k gold leaf → ideal for exterior and high-exposure areas
- 18k–22k gold leaf → suitable for interior restoration
Higher karat gold contains fewer alloy metals, making it more resistant to tarnish and environmental impact.
Loose vs Transfer leaf
- Loose leaf → preferred for detailed, traditional restoration work
- Transfer leaf → easier handling for larger or vertical surfaces
The choice depends on your technique, surface, and level of precision required.
FAQs on Genuine Gold Leaf
Why 23k minimum for exterior work?
Because higher karat gold (23k–24k) contains fewer alloy metals, making it highly resistant to tarnish and environmental damage. Lower karat gold can oxidize over time when exposed to weather.
What causes gilding failure?
Poor surface preparation, incorrect adhesive timing, moisture exposure, and using the wrong type of leaf (e.g. imitation instead of genuine) are the most common causes.
Oil size open time explained
Open time is the period when the adhesive is tacky and ready for leaf application. This can range from a few hours to over 12 hours depending on the size used. Applying too early or too late leads to poor adhesion.
Burnishing vs non-burnished finish
Burnishing creates a high-gloss, mirror-like finish using water gilding. Non-burnished (oil gilding) results in a softer, satin or matte finish and is more durable for exterior use.
Heritage compliance considerations
Restoration projects often require materials and techniques that match the original work. This includes using genuine gold leaf, traditional methods, and following conservation guidelines or local heritage regulations.
