Gold leaf is typically attached using an adhesive, a process central to gilding.
Using Adhesive for Gold Leaf Application
The primary method for attaching gold leaf involves applying a suitable adhesive to the surface where the leaf is to be placed. This adhesive, often referred to as "size," creates a tacky surface that the delicate gold leaf adheres to.
Application Based on Surface Type
The type of surface you are gilding over can influence the specific adhesive used and the preparation required.
Gilding Over Acrylic
When gilding over acrylic surfaces, a common approach is to brush on a water-based adhesive. This type of adhesive provides the necessary tackiness for the gold leaf to bond with the acrylic paint.
Gilding Over Oil Paints
Gilding over oil paints requires careful preparation, particularly regarding the paint's drying time.
- If you are gilding over oil paints, it is crucial to make sure the paint is dry through.
- This drying process for oil paints can take several months.
- Attempting to gild over oil paints that are not thoroughly dry can result in the leaf adhering to areas where you do not want it to be, making the application uneven and potentially ruining the finish.
In summary, the attachment of gold leaf relies on the careful application of an adhesive to a prepared surface, with specific considerations needed depending on whether the underlying layer is acrylic or oil paint.
