5.3.1.1 Follow the manufacturer's application instructions for<br />
corrosion removal. Repeat the process until all corrosion is<br />
removed. Allow to air dry prior to the application of a protective<br />
coating.<br />

5.4.1 Organic Zinc-Rich Primers. The primer will be one<br />
of the previously described zinc-rich primers as identified in<br />
Chapter 3.<br />
5.4.1.2 This primer requires top coating when used on exterior<br />
surfaces (refer to Table 5-1).<br />
5.4.2 Inorganic Zinc-Rich Primers. MIL-PRF-23236, Type<br />
I, Class 3 is an inorganic zinc/rich primer that is usually furnished<br />
as two or three components.<br />
5.4.2.1 Follow the manufacturer's instructions for mixing,<br />
thinning, and application.<br />
5.4.2.2 Only those products listed on QPD-23236 are authorized.<br />
5.4.2.3 During application of the MIL-PRF-23236 primer,<br />
the product should be constantly agitated to prevent the zinc<br />
dust from settling.<br />
5.4.1.1 Dry film thickness should be 3.0 mils and approximately<br />
5.0 mils wet.<br />

5.5 PAINTING.<br />
5.6 INORGANIC ZINC PRIMED SURFACES.<br />
NOTE<br />
Prior to total repaint of Hush House, accomplish corrosion<br />
repair procedures in accordance with Paragraph<br />
5.2.<br />
5.5.1 Structural Corrosion Protection. Corrosion protection<br />
for the Hush House consists of MIL-PRF-23236 inorganic<br />
zinc primed steel (door frame beams, support beams, exhaust<br />
tube) and ASTM A446, Grade G210 galvanized panels (roof,<br />
walls, door). This corrosion protection system should be adequate<br />
in all but extremely severe corrosion environments.<br />
5.5.2 Camouflage Requirements. The selection of colors<br />
for an exterior camouflage pattern should be restricted to those<br />
readily available for MIL-PRF-85285. MAJCOM will determine<br />
the need and color requirements for the operating locations<br />
requesting the application of a camouflage pattern to the<br />
Hush House.<br />
NOTE<br />
• To prevent streaking and other problems, it is necessary<br />
to work from the bottom to the top and not<br />
allow previously worked surfaces to dry.<br />
• The amount of surface area to be worked at any<br />
time should not exceed the surface area that can be<br />
epoxy primed and polyurethane topcoated in one<br />
day.<br />
5.6.1 Primer Requirements on the Door Frame Beams,<br />
Support Beams, and Exhaust Tube. Primer requirements<br />
are as follows:<br />
NOTE<br />
Examine the primed surface prior to cleaning. If the<br />
surface appears to be dirty (not oily), then MIL-PRF-<br />
87937, Type IV soap should be sufficient to clean the<br />
surface. If the surface is oily, it will be necessary to<br />
use one of the soaps (MIL-C-43616 or MIL-PRF-<br />
