Tools You Need:
- Paper paint suits
- Disposable gloves
- Eye protection
- Dust sanding mask
- Dual action sander
- Wet and dry 80 grit sandpaper
- Plenty of rags
- Disposable plastic trays
- Plastic containers
- Disposable rollers for Etching Primer
- Disposable brushes for Clear Coat
* Metal Preparation - Reapplication
If your underwater metals are already coated with Propspeed, or if you have other coatings applied, you will need to remove all other coatings before starting the new application. The easiest, fastest and recommended way to do this is with Stripspeed, a solvent-based paint stripper that has been specifically developed to remove foul-release coatings in less than 30 minutes. The thick consistency hangs on vertical and overhead surfaces and is easy to use. Just crack the bottle open to let some air in, shake well for 90 seconds until the consistency is thick and start using. Read the detailed application instructions on how to use Stripspeed here.
- As the last resort, old coatings can be removed using a dual-action or air-driven sander
- You must wear a dust sanding mask when removing old Propspeed - inhaling any residue could be harmful
* Metal Preparation - 80-grit Profile
Once you have successfully removed the previous coating, sand the metal to achieve an 80-grit profile to prepare the surface for a mechanical bond with the first coat of Etching Primer. This applies to all first-time Propspeed applications as well and can be done using a dual-action sander, or by hand using wet and dry 80-grit sandpaper.
With any surface coating, proper surface preparation is essential.
- High-pressure clean to remove marine foul from the surface, then allow sufficient time to dry
- Old coatings need to be removed completely before a fresh Propspeed coating can be applied
- Ensure the surface is thoroughly dry before sanding, and you can wet sand difficult areas
1 Initial Clean
- All surfaces must be wiped down with Propclean
- Ensure there is no residue remaining
2 Metal Conditioning
You are now ready to start painting.
- Use Propprep liberally
- All surfaces must be wiped down
- Product flash time
- 3-5 min @ 27°C / 80°F
- Optimal application temperature range
- 16°C / 60°F - 32°C / 90°F
- Curing time
- 8 hours @ 27°C / 80°F
3a&b Etching Primer
Note: Failure to thoroughly mix the Etching Primer Base, as described above, may lead to premature hardening, inconsistencies and short life expectancy of the final coating system.
Once there are no solids left in the can, add the Etching Primer Hardener to the can and mix again. Any product not being used immediately can be re-sealed in the can and left in the shade for up to 6 hours.
- Ambient temperatures influence the application process
- Check weather conditions beforehand
- Consider using a thermometer for exact ambient temperatures
4 Clear Coat
- Do not use a foam roller
- Apply much like conventional varnish
- Touch up runs or sags within 5 to 10 minutes
