Gilded Interior Dome and Exterior Dome Application
The process of gilding an interior or exterior dome is not as complicated as one might think. However, care, skill, and the right tools are needed to cause the finished product to run out correctly. Of course, most gilded domes are completed by professionals, and as such, tools and application methods will change depending on the project and the technologies available. The following is a snapshot of what the process of a dome guild might look like, but remember, the method used to apply layers of gold leaf will vary from project to project.
The following is often needed for gilding domes in churches, government buildings, and other important architectural structures:
- Genuine gold leaf- Using gold leaf that is genuine is important, especially if you are gilding outdoors. Pure gold is known for longevity and does not require sealant.
- Lifting machinery (or ladder)- You’ll need to utilize some kind of machinery or ladder to suspend yourself high enough to complete the gilding process. As always, use proper safety measures (LINK) when applying gold leaf while in suspension.
- Proper primer- There are several types of primer that can be used that vary depending on the project. Always use the proper primer for the location and project, and do your best to stick to yellow or red toned primers for the best enhancement of the color of the gold itself.
- Oil or water based primer- If the dome is exterior, you must lay any gold leaf using oil primer. This is the only primer resistant to weather elements. You can utilize either oil or water based primer for interior application.
- Brushes- Squirrel hair brushes are common for the application of gold leaf. Depending on the process and intended outcomes, other brush or tool types may be used.
Gilded Dome Process
There is a general process for applying gold leaf to domes. Please note that the following process will vary greatly depending on the project at hand. Know that dome building will take a long while to complete, and therefore, it is important to pay close attention to your oil or water based tack times to ensure you are able to lay your gold leaf while the glue is still tacky and wet.
The following is the general process for laying gold leaf over a dome:
- First, prep and smooth the surface of the object. This may require sanding, repainting, or removing paint from a previously painted surface prior to application.
- Once the surface is prepared, it is ready to receive primer. There are several types of primer to use with zinc chromate being one of the more popular options. Allow the primer to fully dry before moving onto the next step.
- Apply your oil or water based size. Remember that oil size is most important if the dome is stationed outdoors. Indoor domes can receive fresh gold leaf, re gilding, or gold leafing repairs using water or oil size.
- Allow your size to achieve the proper tack .The size should feel tacky but should not be too wet nor too dry.
- Apply your gold leaf using a squirrel haired soft brush or other forms of equipment. Some gliders use gold leafing rolls to make this process easier.
- Leave the gold leaf to dry. Restore any knicks, gaps, or imperfections in your gold leaf by adding more gold leaf on top of it.
- Finally, remember that the use of genuine gold leaf does not require sealant. Pure gold is resistant to tarnishing. If you do opt to use varnish, doing so may lead to corrosion or a milky white haze over your gold paper over time. Consequently, attempting to protect your genuine gold may end up causing you more headache in the long run.
