17.4. Painting
After composite structure repairing, repaired place should be grinded dry with
sand
paper „120”, next it should be filled with epoxy resin with addition of talc and
titanium white. After filler is hardened, grind it dry with sand
paper “120” and then
“220”.
Repaired area deviations should not exceed 0,01
2”. Wings control can be
done with rigid (along the span) or flexible (along the chord) straight edge. Fuselage
control can be made by soft straight edge.
After grinding with sand
paper „220” spray two times crosswise polyurethane or
acrylic enamel. Sailplane outer surfaces should be painted with white paint, not
getting yellow (apart from wing tips and tailplane tips).
After enamel hardening grind it with sandpaper
„220”, „320”, „400”, „600”, and
then polish it with buffing paste.
Ailerons, rudder and elevator after repair and painting must be balanced in
accordance with guidelines specified in Section 9. of this Manual.
NOTE:
Sailplane upper surfaces (both wings, tailplane and fuselage) can be
painted only in white (except for plane wingtips and long wingtips
area outside aileron span). It is not allowed to place on them any
additional markings or patterns in different colours.
It is acceptable to place competition starting markings on vertical
stabilizer.
