PRODUCT APPLICATION
SURFACE PREPARATION
ALL SURFACES: Remove all dirt, grease, oil, salt, and
chemical contaminants by washing the surface with
Krud Kutter
®
PRO Cleaner Degreaser. Mold and mildew must
be cleaned with Krud Kutter PRO One Step Cleaner &
Disinfectant. Rinse thoroughly with fresh water and allow to fully
dry. All surfaces must be dry at time of application.
STEEL: Hand tool (SSPC-SP-2) or power tool (SSPC-SP-3)
clean to remove loose rust, mill scale, and deteriorated previous
coatings. Abrasive blasting to a minimum Commercial Grade
(SSPC-SP-6, NACE 3) with a 1-2 mils (25-50µ) surface profile
is recommended for optimal performance. Abrasive blast
cleaned steel requires two coats of primer.
GALVANIZED STEEL: New galvanized steel should be
cleaned with Krud Kutter PRO Cleaner Degreaser to remove
all post galvanizing treatments such oil, grease, or wax. Old
or existing galvanized steel should be thoroughly washed to
remove all surface contaminants.
CONCRETE AND MASONRY: Hand or power tool clean to
remove all loose or unsound concrete, masonry, or previous
coating. Very dense, non-porous concrete should be acid
etched or abrasive blasted to remove the laitance layer and
create a surface profile. Allow new concrete to cure for 30
days before coating. Not for horizontal surfaces.
PREVIOUSLY COATED: Previously coated surfaces must
be sound and in good condition. Smooth, hard, or glossy
finishes should be scarified by sanding to create a surface
profile. The ROCAcrylic Direct-to-Metal Acrylic Enamel
3800 is compatible with most coatings, but a test patch is
suggested.
WARNING! If you scrape, sand, or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO
LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN.
PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE.
Wear a NIOSH-Approved respirator to control lead
exposure. Clean up carefully with a HEPA vacuum and a
wet mop. Before you start, find out how to protect yourself
and your family by contacting the National Lead Information
Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
PRODUCT APPLICATION (cont.)
APPLICATION
Apply only when the air, surface, and material temperatures
are between 40-100°F (4-38°C) and the surface temperature
is at least 5°F (3°C) above the dew point. Air temperature
must remain above 40ºF during curing process. The relative
humidity should not be greater than 85%.
The dry times published on page 4 are under conditions of
70-80°F (21-27°C) and a relative humidity of 50%. At lower
temperatures, the dry times will be increased, and the full
development of the coating’s physical properties will take
longer. Improved air flow will aid the curing process when
temperatures are below 50°F or the relative humidity is
greater than 80%.
EQUIPMENT RECOMMENDATIONS
(Comparable equipment also suitable)
BRUSH: Use a good quality synthetic bristle brush.
ROLLER: Use a good quality lamb’s wool or synthetic fiber.

Caution: Protect surrounding surfaces from over spray.
Over spray can be wet or dry depending on height of work,
weather, environmental conditions, and application
equipment. Wet over spray can adhere to unwanted
surfaces. Dry over spray may be removed by wiping or
washing. Always clean dry over spray from hot surfaces
before fusing occurs as surface temperatures can be higher
than the air temperature.
THINNING
BRUSH/ROLLER: Normally not required. When necessary,
thin with fresh water.
AIR ATOMIZED SPRAY: Up to 1 pint per gallon.
AIRLESS SPRAY: Up to ½ pint per gallon.
CLEAN-UP
Soap and water.
