APPLICATION:
SPRAY
- Seal the wood using Cardinal’s 2059-CLE18773 vinyl nitro sealer.
- Scuff sealer lightly with scotch brite or 400 grit sandpaper.
- Apply finish with a fine finish spray gun setup using the necessary amount of atomizing air pressure to form a fine spray.
- Recommended spray gun settings would be 6” fan approximately 9”-12” from the substrate.
- Apply the finish with an overlapping spray technique two times for one coat. Avoid getting the gun to close to substrate to prevent air entrapment (bubbles)
- Apply approximately 0.5-1.0 dry mils (5-10 wet mils) each coat.
- Five to seven coats recommended. Allow seven days air dry under standard conditions to fully harden.
FINAL FINISH
- Once the coat has been air dried for seven days the surface needs to be prepped for buffing.
- Sand the finish with a variety of different fine grit sand papers removing any blemish or contaminant. Start with 600, then work up the final wet sand of 1000-2000.
- Buff the finish using a variety of fine finish wheels with the Mezerna 16-18 buffing compound. The speed on the wheel should be between 750-1000 rpm.
- For final finish use a fine polishing cloth with a water based polish compound.
