The water-based release primer works perfectly for ceramic slumping and casting moulds.
Key features:
- Easy-release spray-on 12oz bottle
- The best release available for texture moulds and Colour de Verre casting moulds
- Can go to temperatures as high as 1800F
Working notes:
- Once Boron Nitride has been used on your mould, you cannot put traditional primers such as primo on top. Use only Boron Nitride for all future firings.
- This spray Boron Nitride is not suitable for stainless steel or metal moulds.
Instructions (included on the bottle):
- Shake vigorously until the marble is heard and there is no sediment
- Uncap and save the cap. Always start with a clean sprayer/tube and screw it onto the bottle
- Test the sprayer on cardboard. Spray lightly (using side-to-side motion) on the mould and allow time to soak in and dry. Please note: This will take longer to dry than solvent based aerosols
- Once the coating is dry to touch, reapply a second coat if desired or if there are bare spots
- Wet coating can be smoothed with a small brush
- Allow time to dry before using. Can be dried at room temperature or with a dryer
- After use, remove sprayer and flush with water. Recap bottle with original cap
For stainless steel moulds, use our Premium or Economy Boron Nitride sprays.
