PAINTING INSTRUCTIONS (Contd)
WARNING
Wear neoprene gloves and eye protection when mixing or coating
KS 55. Skin irritation or eye damage may occur if procedure is
performed without neoprene gloves or eye protection.
Ensure proper ventilation and wear a respirator apparatus when
working with KS 55. Injury to personnel may occur if used in a
confined area.
Wash hands and wrists with skin protectant and rub with skin
protectant ointment before and after performing task. Skin
irritation may occur if hands and wrists are not properly cleaned
and protected.
NOTE
Ensure area to be coated is dry.
Coat bridge in a temperature range of 6475F (1824C).
Coat roadway within eight hours of cleaning. If roadway coating
shows any contamination, perform a follow-up treatment in
compliance with E 02 005 0803.
Pre-heat the area to be coated to a temperature range of 6877F
(2025C).
2.
With a 7 in. (18 cm) lamb-wool roller, apply a 0.04 in. (1 mm) layer of non-skid surface compound to
roadway. Let compound dry for one hour at 72F (22C) or two hours at 64F (18C).
3.
Apply a special corundum mixture (aluminum oxide) with granulation 0.020.04 in. (0.51 mm).
4.
Let corundum mixture dry for twelve hours at temperatures of 59F (15C) or above.
5.
Sweep off non-adhering corundum granulation and use for further application. Sieve out potential
CAUTION
Stack parts with sufficient ventilation to allow coating to complete
the setting process. Coating may be damaged if parts are stacked
directly on top of one another before coating has set.
6.
If stacking coated parts, use wooden blocks as spacers to assure sufficient space between parts.
CAUTION
Coatings can stand full chemical and mechanical stress after seven
days of normal temperatures. Coating may be damaged if exposed
to stress before it is completely dry.
NOTE
Once KS 55 has hardened, it cannot be removed and used for
further application.
7.
Store parts in the open after 48 hours of temperatures 6475F (1824C).
CAUTION
Scrub tools and equipment after each use. Dipping equipment and
tools in solution does not constitute sufficient cleaning. Insufficient
cleaning may cause damage to equipment.
8.
Clean equipment and tools after each use with methychloroform (non-combustible).
b. Repair of Damaged Roadway Cover.
CAUTION
Repair damage to coating as quickly as possible. Damage to coating
may cause further damage to metal surface.
1.
Removing coating from damaged area with scrapers and steel brushes until coating around
damaged area becomes adhesive.
2.
Clean damaged area until all coating is removed from metal.
