Fix a chipped corner or rebuild a small missing piece with putty you can shape. Starbond White Epoxy Putty is a two-part epoxy putty stick for small repairs on suitable ceramic, wood, metal and PVC. This white repair putty is moldable and suits light-colored decorations, small sculpture repairs and craft projects. The putty uses a 1:1 mix ratio. Cut off what you need, then knead the two parts until the color is even. Press the putty onto the clean, prepared surface and shape the repair. It starts setting quickly, so have your tools ready and mix small amounts. After full cure, sand and paint to match the shape and finish around it. Test unfamiliar surfaces first.
For fossil restoration on a display, use the putty to replace a small missing edge when the repair is right for the specimen. Record what you add. On a fossil replica or model, it can be considered for small seam fills and details you can shape quickly. Test the casting material first and remove any mold-release residue that could prevent a bond. Bigger sculpting jobs need a putty with more working time. Before adding permanent filler to a scientifically important fossil, ask a conservator or qualified preparator to assess the repair. Choose White Putty when you need to add missing material and want a light finish.
