surface remains wet. Rinse with water applied by clean rags or sponges.
C. Solvent Cleaning: Use solvent cleaning to remove oil, grease, smoke, and other contaminants
from painted or unpainted surfaces before other preparation work. Wipe surfaces with solvent
using clean rags and sponges. If necessary, spot-solvent cleaning may be employed just prior to
commencement of paint application, provided enough time is allowed for complete
evaporation. Use clean solvent and clean rags for the final wash to ensure that all foreign
materials have been removed. Do not use solvents, including primer thinner and turpentine, that
leave residue.
D. Mildew: Clean off existing mildew by scrubbing with bristle brush or sponge and detergent
solution. Scrub mildewed areas with mildewcide. Rinse with water applied by clean rags or
sponges.
E. Chemical Rust Removal:
1. Remove loose rust scale with specified abrasives for ferrous-metal cleaning.
2. Apply rust remover with brushes or as recommended in writing by manufacturer.
3. Allow rust remover to remain on surface for period recommended in writing by
manufacturer or as determined by preconstruction testing. Do not allow extended dwell
time.
4. Wipe off residue with mineral spirits and either steel wool or soft rags, or clean with
method recommended in writing by manufacturer to remove residue.
5. Dry immediately with clean, soft cloths. Follow direction of grain in metal.
6. Prime immediately to prevent rust. Do not touch cleaned metal surface until primed.
F. Mechanical Rust Removal:
1. Remove rust with specified abrasives for ferrous-metal cleaning. Clean to bright metal.
2. Wipe off residue with mineral spirits and either steel wool or soft rags.
3. Dry immediately with clean, soft cloths. Follow direction of grain in metal.

uniform final appearance without streaks.
b. After work is complete, remove protection no longer required. Remove tape and
adhesive marks.
2. Brushes: Use brushes that are resistant to chemicals being used.
a. Metal Substrates: If using wire brushes on metal, use brushes of same metal
composition as metal being treated.
B. Paint Removal with Hand Tools: Remove paint manually using hand-held scrapers, wire
brushes, sandpaper, and metallic wool as appropriate for the substrate material.
C. Paint Removal with Alkaline Paste Paint Remover:
1. Remove loose and peeling paint using water, scrapers, stiff brushes, or a combination of
these. Let surface dry thoroughly.
2. Apply paint remover to dry, painted surface with brushes.

b. Use mechanical removal methods.
5. Repeat process if necessary to remove all paint.
3.6 SUBSTRATE REPAIR
A. General: Repair substrate surface defects that are inconsistent with the surface appearance of
adjacent materials and finishes.
B. Gypsum-Plaster and Gypsum-Board Substrates:

seams cannot be blended.
3.7 PAINT APPLICATION, GENERAL
A. Comply with manufacturers' written instructions for application methods unless otherwise
indicated in this Section.
B. Prepare surfaces to be painted according to the Surface-Preparation Schedule and with
manufacturer's written instructions for each substrate condition.
C. Apply a transition coat over incompatible existing coatings.
