PAINTING, REFINISHING, AND MARKING

TM 11-5820-489-20

TO 31R4-2GRA6-32

Only use a cleaning solvent when absolutely necessary. Make sure that the cleaning compound

is approved and that the following warning is followed:

Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE.

Prolonged breathing of vapor should be avoided. The solvent should not be used near

heat or open flame; the products of decomposition are toxic and irritating. Since

TRICHLOROTRIFLUOROETHANE dissolves natural oils, prolonged contact with skin

should be avoided. When necessary, use gloves which the solvent cannot penetrate. If

the solvent is taken internally, consult a physician immediately.

2-14. PAINTING, REFINISHING, AND MARKING

Refinishing procedures should restore equipment surfaces to original appearance and as-new

standards. Minor damage to finishes, such as small scratches, require touch-up painting of the af-

fected areas only. Major surface damage requires complete repainting. Inspect the equipment to

determine the extent of painting and refinishing that is required. Refer to MIL-F-14072 for deter-

mination of paints, finishing processes, and quality assurance provisions. Instructions for major

surface repainting are given in TM 43-0139.

A. Touch-up Procedures.

q Remove all rust and corrosion by lightly sanding the affected

area with fine sandpaper

(NSN 5350-00-264-3465). Clean with solvent and allow to dry.

q Apply zinc chromate primer 0.0004 and 0.0006-inch thick per

Federal Specification TT-

P-1757 over the chemical film using small camel's hair brush.

Allow to dry.

q Apply one coat of lusterless enamel paint. Refer to SB 11-573

for available paint and

preservation supplies. Allow to dry.

B. Major Repainting Procedures.

q Complete repainting procedures should be performed only as required. Paint the

equipment in accordance with the requirement of MIL-F-14072 and current established

painting practices.
