MAINTENANCE MANUAL
G. Resurfacing
P/N 74-451-L resurfacing kit provides an oil resistant urethane coating. The "L" Kit can be used to
refurbish weathered deicers to extend service life, or to provide oil resistance to newly installed
deicers. Apply the kit as follows:
CAUTION: AFTER KIT NO. 74-451-L IS APPLIED TO A NEOPRENE DEICER, THE DEICER
SHOULD BE TREATED AS AN ESTANE® DEICER FOR MAINTENANCE
PURPOSES.
CAUTION: DO NOT USE AGEMASTER® NO. 1 AFTER 74-451-L KIT APPLICATION.
NOTE: Deicers coated with 74-451-L kit may be repaired with 74-451-AA patch kit or 74-451-AE
pinhole repair kit.
(1) 74-451-L kit covers 40-50 square feet of deicer surface.
(2) Wash deicer surface with mild soap and warm water to remove contamination.
(3) Remove ShineMaster® cosmetic treatment with ShineMaster® Prep cleaner.
(4) Lightly sand surface with Scotch Brite TM fine grade abrasive material or equivalent.
(5) Clean surface with clear water and dry with lint free cloths to remove soap residue and loose
particles raised from sanding.
CAUTION: DO NOT USE MEK ON ESTANE® SURFACE DEICERS AS MEK WILL ATTACK
ESTANE®.
(6) Wipe surface twice with cleaning solvent. Use MEK or Toluene on neoprene deicers; use only
Toluene on Estane® deicers.
(7) Apply masking tape to leading edge against edges of deicer.
(8) Apply primer:
(a) For Estane® deicers, skip to step (9).
(b) For neoprene deicers only:
1 Mix primer coat with two (2) ounces of accelerator.
2 Apply one even coat of primer mixture to deicer surface. Brush perpendicular to
deicer tubes using short strokes in one direction for smooth finish.
3 Let dry 30 minutes.
(9) Apply protective coat:
(a) For Estane® deicers, use protective coat alone.
(b) For neoprene deicers, mix protective coat with two (2) ounces accelerator.
(c) Apply one even coat of protective coat. If desired, a second coat of protective coat may be
applied within fifteen (15) minutes to one (1) hour of first coat.
(10) Remove masking tape as application is made, about every three (3) feet.
(11) Aircraft may be flown and deicer inflated after 4 hours dry time.
(12) Do not use AgeMaster® No. 1 after 74-451-L kit application.
(13) Deicers coated with 74-451-L kit may be repaired with 74-451 AA patch kit or 74-451-AE
inhole repair kit.
