Imitor, for antiquing varnished instruments
JOHA® Imitor
Targeted Etching for Authentic Antique Effects
JOHA® Imitor is a professional specialty product for artificially aging the varnish on string instruments. It allows violin makers and restorers to realistically replicate decades of natural wear – precisely, effectively, and under full manual control.
The Imitor is applied using a fine brush or an open-pored natural sponge. While the brush enables exact lines and worn edges, the sponge creates irregular, point-like etching patterns across surfaces – ideal for authentic, naturally aged appearances.
The product begins working immediately: It etches the varnish as long as it remains on the surface, and stops only when wiped off with water. The depth and intensity of the effect can be precisely controlled through the exposure time. The resulting changes are irreversible – the effect is permanent and cannot be undone. Professional experience and precision are therefore essential.
After etching, the affected areas are traditionally filled with dark color, nut stain, or antique patina. These substances settle into the etched recesses and enhance the structure, depth, and classic antique look of the instrument. A final layer of varnish can then be applied to blend the effect into the surface and visually tone down the aged areas, creating a harmonized and elegant finish.
Key Benefits:
- Targeted or surface-wide etching of varnish layers
- Application with fine brush or natural sponge
- Effect stops once wiped off with water
- Permanent, irreversible visual changes to the varnish
- Subsequent filling with dark color, nut stain, or patina
- Optional final varnish layer for optical refinement
- Ideal for antique finishes, touch-ups, and restorations
Application Notes:
- Use only on fully cured varnish surfaces
- Do not apply to bare wood
- Always test on a sample surface before full application
⚠️ Important Notice:
JOHA® Imitor is intended for use by experienced professionals only.
Incorrect or careless application can lead to permanent varnish damage. The product chemically etches the varnish and causes irreversible surface alterations. Always test thoroughly on a sample area before use.
