3. Initially patch holes in metal or wood signs with an adhesive backed metal foil over a dry face to provide backing for reflectorized sheeting.

4. Cover all metal foil backing with a patch of Class 1 sheeting sized at least 1 inch larger, but not more than 2 inches larger than the backing material. The patched area shall be free of air bubbles and be oriented to the pattern, if any, of the reflective sign face.

5. Where patching overlaps the existing legend or there is other damage to the legend, restore the affected letter/numerals to full legibility with Type L-3 direct applied characters of the color, size, type, and series used on the sign. The applied characters shall be free of air bubbles.

6. Check for missing items on signs such as bolts, washers, nuts, and lag screws. If such items are missing replace them with fittings provided by the Government.

C. Apply New Sign Faces

1. When listed in the Schedule of Items, the Government will furnish 3M Series 9800 Reflective Sheeting or equivalent, mounted on a 5-10 inches aluminum substrate and bearing the appropriate legend for the installation(s).

2. Straighten bent signs. Pound out holes and dents in metal-backed signs to provide a smooth face. Clean and degrease the existing sign face and remove any loose reflective sheeting.

3. Apply the new sign face over the prepared surface by peeling the protective backing, orienting the material and pressing it in place with a roller, working from the center to the edges. Mounting bolt holes may be pre-punched or formed after application by cutting or punching with a suitable tool; use of mounting bolts to form the holes will not be considered acceptable.
