1 Prepare for safe work
Photograph the object, check stability and value, and test the procedure on a hidden area first. Work with ventilation, gloves, and eye and respiratory protection.
⚠ Warning: Old coatings may contain lead, and a valuable antique can lose value with inexpert cleaning. Assess unknown coatings and serious structural damage with a conservator first.
2 Determine the condition and cause
Save the chipped piece if it exists and clean the area with a soft brush. Determine if the substrate is dry and stable.
3 Perform the key check
For a missing part, cut a veneer patch of the same species with the fibers in the same direction, slightly larger than the damage.
4 Do the repair or maintenance
Fit the edges precisely, glue with even pressure between protective blocks, and retouch only after drying.
? Tip: Photograph the initial state and change only one thing at a time. This makes it easier to determine what really solved the problem.
5 Test the result
Let the glue, coating, or finish dry completely according to the manufacturer, then gradually load the item and inspect the joints in good light.
