When gilding outdoors, it’s best to use 24k Pure Gold Triple Strong Leaf or 23.5k Ducate Double Polish. These options are more durable and brighter, ensuring they last much longer in extreme weather than other gold leaves.

The ideal adhesive for outdoor gilding is Instacoll Base Size, available in both yellow and clear varieties. You’ll also need the Instacoll Activator to reactivate the base. For detailed instructions, refer to the guide titled “How to Use Instacoll Gilding Size.”

Additionally, consider sealing the gilded surface with a varnish, such as Leaf Protect, to help protect the gold leaf.
