(2) Application of Paint
Note: Paint can be applied over the sealer if applied within the time frame set by the
manufacturer.
If set time of the sealer is unknown, beyond the manufacturer allowed limit, or if
the surface required rework, the surface must be sanded with 400-grit wet/dry
sandpaper and solvent cleaned with DX 330 prior to top coating.
As an alternative to wet-sanding, the entire surface may be abraded with a fine
grade of Scotchbrite. Scotchbrite will not flatten the surface, only remove gloss.
Wet sand if the surface requires flattening.
Over large areas, the top coat should not exceed 4-mil. No more than 5% of the
total surface area shall have top coat thicker than 4-mil. Top Coat thickness is ver-
ified by multiplying the average dried thickness by the number of coats applied.
See manufacturer's information for average dried thickness.
(a) Acquire necessary tools, equipment, and supplies.
(b) If required, wet-sand entire surface to be top coated with 400-grit wet/dry sandpaper. Dry
thoroughly after wet sanding.
(c) Mask off all surfaces that do not require top coat or where top coat is not permitted. (Refer
to 51-30)
(d) Solvent clean the application area with DX 330. (Refer to 20-30)
Note: Wipe surface in one direction only to prevent smearing contaminates. For
maximum results, wipe dry with clean white cloths in one direction only,
while the surface is still wet.
(e) Visually inspect prepared surface for imperfections prior to application of top coat. Rework
and solvent clean any damaged or defective areas prior to further operations. (Refer to 20-
30)
(f) Wipe the entire area to be painted with a tack cloth.
