TECHNICAL DATA
9800 SYSTEM DTM URETHANE MASTIC
.PRODUCT APPLICATION (cont.) .
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. WARNING! If you scrape, sand or remove old
paint from any surface, you may release lead paint 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. Carefully clean up with a wet mop or HEPA vacuum.
For additional information contact the U.S.EPA/Lead Information
Hotline at 1-800-424-LEAD or log onto www.epa.gov/lead.
GALVANIZED METAL: Remove oil, dirt, grease and other chemical
deposits with Pure Strength
®
Cleaner/Degreaser item #3599402 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.
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.
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

Industrial Primers: 9360 or 9370.
EQUIPMENT RECOMMENDATIONS
BRUSH: Good quality natural or synthetic bristle recommended.
