The Instacoll Gilding System consists of two components: Component 1 is the Base, and Component 2 is the Activator. Instacoll serves as a gilding size (adhesive) for all types of genuine leaf, suitable for both indoor and outdoor use. The size is applied using a fine synthetic brush.
After applying the base layer, it needs to become sticky, which can take up to one hour. Once dried, you can gild for up to one hour without using the Activator. If you’re working on a larger project and need a longer-lasting gild, wait until the size is completely dried out and then reactivate the surface with the Instacoll Activator.
The Instacoll HA is ideal for larger gilding projects. You can apply Instacoll to any surface, let it sit for a few hours until it becomes sticky, and then start gilding. You don’t have to worry about the size drying too quickly, as you have at least 2 to 3 days to complete your gilding before the stickiness begins to fade.
Instacoll color variation
You can use any colour for gilding; however, the colour variation will result in different finish effects.
Instacoll Yellow Size: This works well with gold leaf, providing a bright and shiny finish.
Instacoll Clear Size: This is ideal for gilding on glass, as it allows the gold to be visible from both sides. It’s also a good option if you prefer a less intense gold finish.
- Gilding on Wood: For untreated wood, it is essential to apply a suitable wood primer or Sealer P first.
- Gilding on Metal: This is a delicate process for gilding metal. Before applying Instacoll, ensure that the surface is well-prepared to protect the metal leaf and prevent corrosion. Begin by using a suitable metal primer, followed by two coats of Instacoll. If the metal will be exposed to outdoor conditions, apply two coats of high-gloss paint ideal for outdoor use. Never apply Instacoll Base on powder-coated surfaces; always use a primer.
- Gilding on Glass: You can use Instacoll Base Size (clear) on glass, but this should only be done for interior projects.
Preparing the Surface for Gilding
The surface must be dry and free from dust and grease. It should be treated to ensure weather resistance without a gilding finish.
- Apply one or two layers of Instacoll size to cover the surface thoroughly.
- If you are using Transfer Gold Leaf, allow the Instacoll to dry completely for at least one hour. This technique is preferred for gilding without the use of gesso. However, if you are using Loose Gold Leaf, apply the gold leaf while the Instacoll is still wet.
- Once the Instacoll is dry, use a Gilder’s Brush to apply the Activator. Allow it to dry for 5-10 minutes.
- Place the gold leaf face down and press it down with the Instacoll Tissue.
- Gently peel off the transfer paper. Press the gold leaf with the Instacoll Tissue one more time, and then brush off any excess gold using the Gilder’s Mob/Duster. Carefully polish the gold with the Instacoll Tissue.
Note that gilding time is unlimited. If you’re working on a large project, you can re-use the Activator to reactivate the Instacoll adhesive and continue gilding, even months later. Once completed, the gilded product can be exposed to moderate weather conditions immediately.
Important: The Activator (component 2 of 2) is made for Instacoll Base (component 1), while the Activator HA (component 2 of 2) is intended for Instacoll HA (component 1).
