Pinhole defects in various materials, such as coatings or films, can be caused by several factors, including poor surface preparation, contamination, or air entrapment during application. Additionally, improper curing or drying conditions can lead to the formation of small voids. In coatings, pinholes may also occur due to the migration of gases or solvents trapped beneath the surface. Environmental factors, such as humidity and temperature fluctuations, can further exacerbate these issues.

How do you avoid pin holes when applying gesso on wood as I can not have any pin holes as I use the aqueous paint egg tempera?
To minimize pinholes start with a fine grained wood. Let the gesso cool and apply it when it becomes thick but not solid. Brush it out in alternating directions with decreasing pressure. Any pinholes that do appear can be filled by dampening the surface and rubbing gently with a fingertip, a cloth or very fine sandpaper. Keep on top of this as you build layers of gesso to avoid pinholes popping through from below.
