PACKAGING (cont.)
TINT BASES (cont.)
Yellow Base – The yellow tint base can accept up to 16 ounces of
colorant per gallon. Not available in fives or in Satin.
Masstone Base – The clear tint base can accept up to 16 ounces of
colorant per gallon.
Deep Base – The deep tint base contains 0.8 pounds of titanium
dioxide per gallon. It can accept up to 12 ounces of colorant per gallon.
Light Base – The white tint base contains 1.8 pounds of titanium
dioxide per gallon. It can accept up to 8 ounces of colorant per gallon.
The entire container of activator must be added to the tinted base
component, regardless of the amount of colorant used. Colors which
don’t use the maximum load of colorant will yield less than a full
container of activated material.

RECOMMENDED PRIMERS
9800 System DTM Urethane Mastic is self-priming and can be used
without a primer in mild to moderate exposures. The use of a primer
is required in severe exposures and on heavily rusted surfaces. Also,
aluminum should be primed.
The following primers are recommended for conditions indicated:
• 9100: Severe conditions; (9115 should not be used as a primer)
• 9360 or 9370: Severe conditions; these primers can be
topcoated within 30 days, enhanced adhesion over aluminum.
• 5369, 5381: Moderate conditions; enhanced adhesion over
aluminum.
• 2068, 2082: Mild to moderate conditions; where a single-coat,
fast dry primer is needed.
PRODUCT APPLICATION
SURFACE PREPARATION
ALL SURFACES: (SSPC-SP-1) Remove all dirt, grease, oil, salt and
chemical contaminants by washing the surface with Krud Kutter
®
Original Cleaner Degreaser or other suitable cleaner. Mold and
mildew areas must be cleaned with a chlorinated cleaner or bleach
solution. Rinse with fresh water and allow to dry.
STEEL: Hand tool (SSPC-SP-2) or power tool (SSPC-SP-3) clean to
remove loose rust, scale, and deteriorated previous coatings to obtain
a sound rusted surface. For optimum corrosion resistance, abrasive
blast to commercial grade SSPC-SP-6, with a blast profile of 1-2 mils
(25-50µ). All weld spatter should be removed along weld seams,
rough welds should be ground smooth, and all sharp edges should be
ground to a smooth radius.
PREVIOUSLY COATED: Previously coated surfaces must be sound
and in good condition. Smooth, hard, glossy or aged two-component
epoxy coatings should be scarified by sanding or sweep blasting to
create a surface profile. The 9800 System DTM Urethane Mastic is
compatible with most coatings, but a test patch is suggested.
GALVANIZED METAL: Remove oil, dirt, grease and other chemical
deposits with Krud Kutter
®
Original Cleaner Degreaser or other
suitable cleaner. Remove loose rust, white rust or deteriorated old
coatings by hand or power tool cleaning or brush off blasting. Rinse
thoroughly with fresh water and allow to fully dry.

SURFACE PREPARATION (cont.)
CONCRETE OR MASONRY: New concrete or masonry must cure 30
days before coating. Any concrete surface must be protected from
moisture transmission from uncoated areas. Remove all loose,
unsound concrete. Remove laitance and create a surface profile by
acid etching with Rust-Oleum 108402 Cleaning and Etch Solution or
by grinding. Surface sealers and curing agents must be removed by
grinding.
MIXING
Thoroughly mix the base component to ensure any settled pigment is
re-dispersed before combining the components together. Combine at
a 5:1 ratio (base to activator) by volume and mix thoroughly for 2-3
minutes. Power mixing is preferred. Do not mix more material than
you plan to use with the listed pot life.
APPLICATION
Apply only when air and surface temperatures are between 40-100°F
(5-38°C) and surface is at least 5°F (3°C) above the dew point. Can
be applied by brush, roller or spray. For proper performance, a dry
film thickness of 3 to 5 mils (75 to 125µ) per coat is required.
Excessive brushing or rolling may reduce film thickness. Apply two
coats to an abrasive blast cleaned surface. The 9800 System DTM
Urethane Mastic can accommodate wet-on-wet recoat after 2 hours
of dry time. However this process should be conducted by
experienced painters only. Application must be done by spray, and
since a wet film thickness gauge is impractical during the application
of the second coat, care must be used to avoid excessive film build.
Excessive film thickness or application of the second coat before the
recommended dry time (2 hours) can result with micro-wrinkling or
pinholes; either of which will lower the gloss of the finish. Wet-on-wet
application of the 9800 System Urethane Mastic finish can also be
done over a first coat of 9100 System DTM Epoxy Mastic (except
9115) or one of the Rust-Oleum
®
Epoxy Primers: 9360 or 9370.
EQUIPMENT RECOMMENDATIONS
(Comparable equipment also suitable.)
BRUSH
: Use a good quality natural or synthetic bristle brush.
