| Substrates
& Surface Preparation |
| General
|
Surfaces
must be clean and dry. Employ adequate methods
to remove dirt, dust, oil and all other contaminants
that could interfere with adhesion of the
coating. |
| Steel
|
Immersion:
SSPC-SP10 Non-Immersion: SSPC-SP6 for maximum
protection. SSPC-SP2 or SP3 as minimum requirement.
Surface Profile: 2.0-3.0 mils (50-75 micron) |
| Galvanized
Steel |
Non-Immersion:
Sweep blast to roughen surface and produce
a 1.0-2.0 (25-50 micron) profile. |
| Concrete
|
Concrete
must be cured 28 days at 75° F (24° C) and
50% relative humidity or equivalent. Prepare
surfaces in accordance with ASTM D4258 Surface
Cleaning of Concrete and ASTM D4259 Abrading
Concrete. Voids in concrete may require surfacing. |

| Application
Equipment |
| Spray
Application (General) |
This
is a high solids coating and may require adjustments
in spray techniques. Wet film thickness is
easily and quickly achieved. The following
spray equipment has been found suitable and
is available from manufacturers such as Binks,
DeVilbiss and Graco. |
| Conventional
Spray |

manufacturer. |
| Brush
& Roller (General) |
Recommended
for touch up and striping of weld seams and
hard-to-coat areas. Avoid excessive rebrushing
or re-rolling. |
| Brush |
Use
a medium bristle brush. |
| Roller
|
Use
a short-nap synthetic roller cover with phenolic
core. |
|
| Mixing
& Thinning |
| Mixing
|
Power
mix until uniform in consistency. |
| Thinning
|
May
be thinned up to 12 oz/gal (10%) with Thinner
#10 if needed. When used directly to concrete,
thinning is required on the first coat to
provide adequate “soak-in”. Use of thinners
other than those supplied or recommended by
Carboline may adversely affect product performance
and void product warranty, whether expressed
or implied. |
|
| Cleanup
& Safety |
| Safety
|
Read
and follow all caution statements on this
product data sheet and on the MSDS for this
product. Employ normal workmanlike safety
precautions. Hypersensitive persons should
wear protective clothing, gloves and use protective
cream on face, hands and all exposed areas. |
| Ventilation |
Warning: Vapors may cause explosion. When
used in enclosed areas, thorough air circulation
must be used during and after application
until the coating is cured. The ventilation
system should be capable of preventing the
solvent vapor concentration from reaching
the lower explosion limit for the solvents
used. User should test and monitor exposure
levels to insure all personnel are below guidelines.
If not sure or if not able to monitor levels,
use MSHA/NIOSH approved respirator. |
| Caution
|
This
product contains flammable solvents. Keep
away from sparks and open flames. All electrical
equipment and installations should be made
and grounded in accordance with the National
Electric Code. In areas where explosion hazards
exist, workmen should be required to use non-ferrous
tools and wear conductive and non-sparking
shoes. |

| Industry standards are
for substrate temperatures to be above the dew point.
This product simply requires the substrate temperature
to be above the dew point. Condensation due to substrate
temperatures below the dew point can cause flash
rusting on prepared steel and interfere with proper
adhesion to the substrate. Special application techniques
may be required above or below normal application
conditions. |
