COATING DATA
DESCRIPTION:
A two-component, high solids, chemically cured epoxy coating. Ruff Stuff 3300 is a unique and
outstanding barrier coating for the protection of steel, iron, or concrete exposed to potable water or
aggressive chemical environments. Ruff Stuff 3300 has an extensive history of proven successful use in
lining steel, ductile iron, concrete tanks and pipe subjected to potable water or other aggressive chemical
agents. Ruff Stuff 3300 meets the requirements of American Water Works Association Standard C-210
and the requirements of ANSI/AWWA D102-03 ICS-1. Approved under ANSI/NSF International Standard
61 for potable water immersion service in tanks of 1000 gallons and greater capacity and potable water
pipe 20 inches and greater.
USE:
A protective barrier coating for tanks, pipe, and structural elements exposed to potable water or
aggressive chemical agents. It also is ideal for protecting steel and concrete immersed in fresh, sea, and
chemically contaminated water. The very high film build capabilities of Ruff Stuff 3300 makes it ideal for
use over pitted steel or in very corrosive environments as a primer, intermediate or finish coat.

LIMITATIONS:
Do not use for immersion service above 120°F (49°C) or dry heat above 200°F (93°C). Not recommended
for immersion in concentrated solutions of mineral acids or organic acids.
SURFACE PREPARATION:
Steel (Immersion)—SSPC-SP 10 Near White Blast. Steel (Non-Immersion)—SSPC-SP 6 Commercial
Blast. Ductile Iron—Remove all surface contaminants by abrasive blasting. Do not coat surfaces
previously coated with asphalt.
Concrete—SSPC-SP 7 Brush Off Blast. New concrete must cure at least 28 days and contain less than
14% moisture prior to painting. Recoating—Multicoat systems require this product to be recoated. This
product does not require scarifying the surface prior to being recoated with any product listed under
recommended PRIMERS/TOPCOATS. Prior to recoating, remove all chalk and/or other surface contaminants.

Ruff Stuff 3300, PE-54 Epoxy, PE-54 RC Epoxy.
NSF/ANSI Standard 61 potable water immersion topcoats:
Ruff Stuff 3300 Epoxy, PE-54 Epoxy, PE-54 RC Epoxy.
Non-Potable water applications:
Perma-Clean II Epoxy, Armorguard Epoxy, Indurethane 5500 Enamel.
COVERAGE:
Theoretical—962 ft2 per gallon at 1.0 mil dry film thickness.
DRY FILM THICKNESS:
6.0 to 9.0 mils per coat.
WET FILM THICKNESS:
10.0 to 15.0 mils.
APPLICATION DATA
BLEND RATIO:
One part Ruff Stuff 3300 Activator to 9 parts Ruff Stuff 3300 Base by volume. Power agitate until
components are thoroughly mixed. Allow mixed components to stand fifteen minutes prior to application.
POT LIFE:
Eight hours at 80°F decreasing with higher temperature.
APPLICATION:
Airless Spray—Use .029 tip; 30 mesh filter; 30:1 Pump ratio at 80-100 psi operating air pressure. Roll—
Use lambswool cover. Additional coats may be required to achieve desired film thickness. Brush—Use
natural bristle brush. Additional coats may be required to achieve desired film thickness.
THINNING:
If required, thin up to 10% with K-1066 Reducer. Clean equipment with K-1066 Reducer.
CLIMATE:
Use this product only if the substrate temperature and ambient air temperature is above 40°F and is
expected not to decrease for at least two hours after application. Also, the substrate temperature must be
5°F above the dewpoint for a period of at least two hours after application to avoid condensation
occurring on wet paint.
DRY TIME:
TO HANDLE—9 hours at 80°F.
TO RECOAT—50°F or higher, overnight; 40°F-50°F, second day.
IMMERSION SERVICE—50°F or higher, seven days with proper ventilation; 40°F-50°F, 14 days with
proper ventilation. Ventilation during application and after must be in accordance with AWWA D102-03
Section 4.6.5. Due to varying tank designs, interior circulation may be necessary to avoid dead air
spaces.
Note: High film thickness, low temperature and/or poor ventilation will retard dry time.
