as follows:
1. Concrete: 12 percent.
2. Masonry (Clay and CMUs): 12 percent.
3. Wood: 15 percent.
4. Gypsum Board: 12 percent.
C. Exterior Gypsum Board Substrates: Verify that finishing compound is sanded smooth.
D. Verify suitability of substrates, including surface conditions and compatibility, with existing
finishes and primers.
E. 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 and recommendations in "MPI Architectural
Painting Specification Manual" applicable to substrates and paint systems indicated.
B. Remove plates, machined surfaces, and similar items already in place that 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 if any.
2. Do not paint over labels of independent testing agencies or equipment name,
identification, performance rating, or nomenclature plates.
C. Clean substrates of substances that could impair bond of paints, including dirt, oil, grease, and
incompatible paints and encapsulants.
1. Remove incompatible primers and re-prime substrate with compatible primers as required
to produce paint systems indicated.
D. Surface preparation, when noted on painting schedule or on drawings, shall comply with
Surface Preparation Standards by SSPC as follows:

paint manufacturer.
F. Concrete Masonry Substrates: Remove 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.
G. Steel Substrates: Remove rust and loose mill scale. Clean using methods recommended in
writing by paint manufacturer. Refer to Specification Sections 05 12 00 for additional
information.
H. Galvanized-Metal Substrates: Remove grease and oil residue from galvanized sheet metal
fabricated from coil stock by mechanical methods to produce clean, lightly etched surfaces that
promote adhesion of subsequently applied paints. Refer to Specification Sections 05 12 00 for
additional information.
I. Shop-Primed Steel Substrates: Clean field welds, bolted connections, and areas where shop
paint is abraded. Paint exposed areas with the same material as used for shop priming to
comply with SSPC-PA 1 for touching up shop-primed surfaces.
J. Aluminum Substrates: Remove loose surface oxidation.
K. Wood Substrates:
1. Scrape and clean knots. Before applying primer, apply coat of knot sealer recommended
in writing by topcoat manufacturer for exterior use in paint system indicated.
2. Sand surfaces that will be exposed to view, and dust off.
3. Prime edges, ends, faces, undersides, and backsides of wood.
4. After priming, fill holes and imperfections in the finish surfaces with putty or plastic wood
filler. Sand smooth when dried.
L. Plastic Trim Fabrication Substrates: Remove dust, dirt, and other foreign material that might
impair bond of paints to substrates.

B. Tint each undercoat a lighter shade to facilitate identification of each coat if multiple coats of
same material are to be applied. Tint undercoats to match color of topcoat, but provide
sufficient difference in shade of undercoats to distinguish each separate coat.
C. If undercoats or other conditions show through topcoat, apply additional coats until cured film
has a uniform paint finish, color, and appearance.
3.4 CLEANING AND PROTECTION
A. At end of each workday, remove rubbish, empty cans, rags, and other discarded materials from
Project site.
B. After completing coating application, clean spattered surfaces. Remove spattered coatings by
washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces.
C. Protect work of other trades against damage from coating operation. Correct damage to work of
other trades by cleaning, repairing, replacing, and recoating, as approved by Architect, and
leave in an undamaged condition.
D. At completion of construction activities of other trades, touch up and restore damaged or
defaced coated surfaces.
