(8) Cleaning/Painting - Propeller Blades
Propeller blades are painted with a durable specialized coating that is resistant to abrasion. If
this coating becomes eroded, it is necessary to re-paint the blades to provide proper corrosion
and erosion protection. Painting should be performed by an authorized propeller repair station in
accordance with Hartzell Propeller Owner’s Manual and Handbook. It is permissible to perform a
blade touch-up with aerosol paint in accordance with the procedure below.
(a) Acquire necessary tools, equipment, and supplies
WARNING:
Cleaning agents are flammable and toxic to the skin, eyes, and respiratory
tract. Skin and eye protection is required. Avoid prolonged contact. Use in
well ventilated area.
(b) Using acetone, wipe surface of blade to remove contaminates.
CAUTION: Erosion damage is typically very similar on all blades in a propeller assem-
bly. If one blade has more damage, i.e. in the tip area, all blades should be
sanded in the tip area to replicate the repair of the most severely damaged
blade tip. This practice is essential in maintaining balance after refinishing.
(c) Feather existing paint coatings away from eroded or repaired area with sandpaper.
(d) Using acetone, wipe surface of blade to remove contaminates.
(e) Apply corrosion preventative such as Oakite 31 in accordance with directions provided by
manufacturer.
(f) Mask off blades as needed.
