PART 3 EXECUTION
3.1PREPARATION
A.Apply only to surfaces that have been sealed with a penetrating concrete
sealer or concrete coating.
B.Remove fence, signs, reflectors, railings, and similar items already in
place that are not to be coated.
1.Protect items in place before surface preparation and coating if
removal is impractical because of the size or weight of item.
2.Reinstall removed items after completing anti-graffiti coating
installation.
C.Clean substrates of substances that could impair the coating bond before
applying coating.
1.Schedule cleaning and coating application so dust and other
contaminates from cleaning process will not fall on wet, newly coated surfaces.
2.Clean and prepare surfaces to be coated according to the
manufacturer’s written instructions for substrate condition.
a.Remove efflorescence, chalk, dust, dirt, grease, oils, release
agents, and curing compounds. Anti-Graffiti Concrete Coating
D.Remove existing coatings or apply a barrier coat as recommended by the
manufacturer when applying an anti-graffiti coating to an existing surface with an unknown or incompatible sealer or coating.
1.Apply penetrating concrete sealer or concrete coating that is
compatible with anti-graffiti coating when existing coating is removed.
3.2GRAFFITI TEST
A.Apply graffiti to two 3 ft by 3 ft test areas selected by the Engineer.
1.Make treated areas sufficiently larger than test areas to prevent
graffiti from marking uncoated surfaces.
2.First test area.
a.Apply solvent based spray paint.
1) Paint using colors black, blue, and red until the test area is completely covered.
3.Second test area.
a.Apply solvent based ink markers.
1) Mark the surface using black, blue, and red colors.
b.Provide marker coverage sufficient to demonstrate the
performance of the anti-graffiti coating.
4.Do not apply anti-graffiti coating to entire surface until the Graffiti
Test has been completed and the Engineer is satisfied with the results.
B.Remove the graffiti in the presence of the Engineer at least five days after
the graffiti application.
C.Consult the manufacturer to determine corrective measures or select
another product if the graffiti is not completely removed.
3.3APPLICATION
A.Do not apply anti-graffiti coating until the penetrating concrete sealer or
concrete coating has properly dried.
B.Apply anti-graffiti coating only when the surface to be coated and outside
air temperature will remain above 45 degrees F for 24 hours.
C.Apply anti-graffiti coating according to manufacturer’s recommended
installation instructions.
