Spirit primer standard, colorless
JOHA® Spirit varnish Standard has similar properties to our proven Spirit varnish Ia. By replacing relatively expensive resins and oils with more affordable resins of comparable quality, a high-quality and economical spirit varnish was created. It dries quickly, remains elastic, and produces a smooth, silky gloss. Thanks to its balanced formulation, it offers good acoustic properties and is versatile for use in instrument making.
Properties
- Spirit varnish based on traditional recipe
- Fast drying
- Elastic coating film
- Silky to glossy surface effect
- Good acoustic properties due to premium natural resins
- Cost-effective alternative to Spirit varnish Ia
Application Notes
JOHA® Spirit varnish Standard is especially suited for experienced users. Because it dries quickly, it requires swift and careful handling. Achieving a uniform coating surface is only possible with appropriate skill and practice, as with all fast-drying spirit varnishes.
Recommended Use
Ideal for coating string instruments such as violin, viola, cello, or double bass as part of a multi-layer spirit varnish build-up. Also suitable for repairs and touch-ups.
Spirit Varnish Build-up
For optimal results, we recommend the classic three-layer build-up:
- Primer: Applied directly to the prepared wood. Provides excellent adhesion and forms the hardest layer in the build-up.
- Color coat: Middle layer, either clear or tinted. Softer than the primer, used to create the desired color effect.
- Coating: Final layer. Technically the softest, creating a rich, deep gloss and protecting the layers beneath.
Drying Times
Drying depends on ambient temperature and humidity. Ideal conditions are about 18 °C (64 °F) and 55% relative humidity.
- Thin spirit varnish layers dry initially (1–3 coats) in about 24 hours.
- Thicker or multiple coats require correspondingly more time.
- Practical test: Press your thumb firmly onto the varnish surface — if no impression remains, the coating is dry.
