G. Proceed with coating application only after unsatisfactory conditions have been corrected.
1. Application of coating indicates acceptance of surfaces and conditions.
3.2 PREPARATION
A. Comply with manufacturer's written instructions applicable to substrates and paint systems indicated.
B. Scraping or sanding surfaces of older buildings (especially pre-1978) may release dust containing lead or
asbestos. EXPOSURE TO LEAD OR ASBESTOS CAN BE VERY HAZARDOUS TO YOUR HEALTH. Always
wear appropriate personal protective equipment during surface preparation, and finish cleanup of any residues
by water- washing all surfaces. For more information, see Dunn-Edwards brochure on "Surface Preparation
Safety" or call EPA's National Lead Information Hotline at 1-800-424-LEAD, or visit www.epa.gov/lead
or/asbestos, or contact your state or local Health Department.
C. Remove hardware, covers, plates, and similar items already in place that are removable and are not to be
painted. If removal is impractical or impossible because of size or weight of item, provide surface-applied
protection before surface preparation and painting.
1. After completing painting operations, use workers skilled in the trades involved to reinstall items that
were removed. Remove surface-applied protection.
D. Clean substrates of substances that could impair bond of paints, including dust, dirt, oil, grease, and
incompatible paints and encapsulants.

1. Pressure wash or water blast to remove oil, grease, dirt, loose mill scale, and loose paint at pressures
of 2500-3500 p.s.i. at a flow of 3.0-3.5 gallons per minute. This is the recommended standard for
optimal efficiency.
H. Prior to application of prime/finish interior and/or exterior coat systems, provide a clean, sound surface free of
dust, dirt contaminants, mildew and efflorescence by use of a power wash and hand scraping or use of
mechanical grinders where necessary. Additionally, areas are to be scrubbed with a bristle brush to insure
complete removal of any residual salts. Remove all labels, stickers, price tags, etc. from surfaces before
priming. Wood areas stamped with ink codes must be spot primed with blocking primers. Power wash areas to
be coated to ensure that new salt deposits do not occur. Failure to do so may cause adhesion issues or result
in delamination and invalidate any manufacturer warranty given or implied. After cleaning if there is still chalk
evident, this condition must be brought to the owner's attention in writing before any further work is done.
I. Cementitious Substrates: (concrete, stucco, masonry) Remove release agents, curing compounds,
efflorescence, and chalk. Do not paint surfaces if moisture content or alkalinity of surfaces to be painted
exceeds that permitted in manufacturer's written instructions.
1. Wire brush all loose and peeling paint and dust all surfaces before spot priming or applying finish coats.
Industry standards apply to applications of cracks, voids, and repairs. Any areas of repair shall be
patched and dried before coatings are applied. Cracks should be repaired as follows: 1. Cracks less
than 14" wide should be filled using Dunn-Edwards Brush Grade Elastomeric Patch. 2. Cracks wider
than 14" should be cut and scraped to a "V" shape and filled with Dunn-Edwards Trowel Grade
Elastomeric Patch. Large cracks and holes may require repeated applications of patching materials to
bring flush with adjacent substrate. Feather-in all repairs and caulking to blend with adjacent substrate.
2. Large holes in stucco / plaster/ concrete will be patched with Rapid Set Premium Stucco Patch or
Rapid Set Wunderfixx Concrete Patching Compound in appropriate texture to blend with existing
texture. Allow stucco patch to cure to acceptable pH level (10) prior to application of prime/finish coat
systems. Caulk large cracks in stucco / plaster/ cement with GE-Life Time 920.
3. Spot prime over all patched areas, cracks, and holes then use appropriate topping material to match
existing surface level and texure.
J. All Steel Substrates: Remove rust, loose mill scale, and shop primer if any. Clean using methods
recommended in writing.
a. SSPC-SP 1, "Solvent Cleaning."
b. SSPC-SP 2, "Hand Tool Cleaning."
c. SSPC-SP 3, "Power Tool Cleaning."
1. All ferrous metals should be thoroughly cleaned and all loose rust or mill scale be removed by wire
brush, scraper and/or power tool, such as an electric drill with a wire brush attachment. Any rust spots
or bare metal should receive the appropriate prime coat. Rust inhibited primer to be applied on all
properly prepared surfaces where rust is evident. Any hard, glossy surfaces should be dulled.
