3.2 PREPARATION
A.Comply with manufacturer's written instructions and recommendations in "MPI
Architectural Painting Specification Manual" applicable to substrates 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 reprime substrate with compatible
primers as required to produce paint systems indicated.
D.Steel Substrates: Remove rust and loose mill scale. Clean using methods
recommended in writing by paint manufacturer.
E.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.

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.
G.Gypsum Board Substrates: Do not begin paint application until finishing
compound is dry and sanded smooth.
H.Plaster Substrates: Do not begin paint application until plaster is fully cured
and dry.
3.3 APPLICATION
A.Apply paints according to manufacturer's written instructions.
1.Use applicators and techniques suited for paint and substrate indicated.

exposed surfaces. Before final installation, paint surfaces behind
permanently fixed equipment or furniture with prime coat only.
3.Paint front and backsides of access panels, removable or hinged covers,
and similar hinged items to match exposed surfaces.
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.
D.Apply paints to produce surface films without cloudiness, spotting, holidays,
laps, brush marks, roller tracking, runs, sags, ropiness, or other surface
imperfections. Cut in sharp lines and color breaks.
E.Painting Mechanical and Electrical Work: Paint items exposed in equipment
rooms and occupied spaces including, but not limited to, the following:
