5.3.1. Paint.

5.3.1.1. Fully Cured Pavement. Apply paint at a wet film thickness of 0.305 millimeter to 0.356 millimeter (12 mils to 14 mils) for a desired dry film thickness of approximately 0.203 millimeter (8 mils). This thickness is needed to properly bind retroreflective beads in the paint. At this rate, coverage will be approximately 3 square meters per liter (121 square feet per gallon).

5.3.1.2. New Pavement. If new pavement surfaces must be opened to operations before being allowed to fully cure, apply temporary markings on new pavement at an application rate that will result in a dry film thickness of

0.102 millimeter to 0.152 millimeter (4 mils to 6 mils); this will produce a marking of sufficient prominence to allow operations. Touch up the marking in the event of bleeding, and remark the pavement at the normal application rate after the pavement is thirty days old.

5.3.2. Apply thermoplastics and preformed reflective tape in accordance with the manufacturer's instructions.

5.3.3. Apply retro reflective media (glass beads) at approximately 3.6 kilograms to

3.9 kilograms per 11.2 square meters (8 pounds to 9 pounds per gallon of paint or 121 square feet) of marked surface area.

5.3.4. Painted markings should not be allowed to build up beyond a total thickness of approximately 1.02 millimeters (40 mils). This will occur after about five marking cycles unless surface abrasion (such as can be caused by snow- removal equipment) reduces this buildup. Over-painting will cause the marking to eventually crack and peel.

5.3.5. To minimize hook-skip potential, ensure paint buildup does not exceed 3.1 millimeters (0.125 inch) within 61 meters (200 feet) on either side of the aircraft arresting system pendant.
