Pro Industrial DTM Wash Primer is not intended for use
over chemical treatments on steel, galvanized steel, or
aluminum. Using this over these chemical treatments
may result in loss of adhesion.
Sanding or light mechanical abrading of hard, smooth
metallic surfaces, such as stainless steel or chrome,
improves adhesion.
Due to the wide variety of substrates, substrate
properties, surface preparation methods, equipment and
tools, application methods, and environments, the
customer should test the complete system for adhesion,
compatibility, and performance prior to full scale
application.

scraped and sanded to a sound surface. Glossy
surfaces should be sanded dull. Stains from water,
smoke, ink, pencil, grease, etc. should be sealed
with the appropriate primer-sealer. Recognize that
any surface preparation short of total removal of the
old coating may compromise the service length of
the system.

Aluminum:
Remove all oil, grease, dirt, oxides, and other
contaminants from the surface by cleaning per
SSPC-SP1.

Galvanizing:

Zinc Rich Coatings:

Remove all oil, dust, grease, dirt, loose rust, and
other foreign material from the surface by cleaning
per SSPC-SP1 or water blast per NACE Standard
RP-01-72. For weathered zinc coatings, remove
zinc salts by either high pressure water washing
and scrubbing with a stiff bristle brush or sweep
blast followed by a water flush. Allow to dry
