Wunda Gilding Size

Wunda Water-Based Size is a synthetic, water-based gilding adhesive designed for interior applications requiring extended working time and reliable performance. This clear, non-toxic, archival adhesive is ideal for use with genuine and composition metal leaf, as well as mica powders, offering flexibility across a wide range of decorative and fine art projects.

Formulated to reach gilding tack in approximately 15–20 minutes, Wunda Size remains open for over 36 hours, making it especially well suited for complex or large-scale applications where extended working time is essential. In many cases, it will remain tacky for an extended period, allowing for precise placement and adjustments during gilding.

Wunda Size is ideal for use on: • Wood, plaster, fabric, walls, ceilings, frames • Fine art and decorative finishes • General interior surfaces

The adhesive applies smoothly and dries clear, allowing the brilliance of the leaf to remain unaffected. It is easy to use and clean up with water, making it suitable for both professional studios and educational environments.

Key characteristics include:

• Clear, non-toxic, and water-based

• Archival quality

• Tack in 15–20 minutes / open time over 36 hours

• Easy clean-up with water

• Interior use only

For surfaces that will be handled or exposed to contact, it is recommended to apply a protective sealer after 48 hours to ensure durability and longevity.

Important: This product is sensitive to temperature and should not be exposed to freezing conditions. Water-based size cannot be shipped if temperatures are below 40°F, as freezing will compromise performance. Contact for shipping availability in colder conditions.

With its extended open time, ease of use, and dependable adhesion, Wunda Water-Based Size is an excellent choice for gilders seeking flexibility and control in interior gilding applications.
