The following procedures should be followed for applying SAFETY COATINGS,
INC. marking paints.
-
All surfaces to be painted
should be completely dry and free of loose dirt, rocks, etc. (Sweeping
before application is recommended.)
-
All new asphalt surfaces should be properly cured before striping. Most asphalt surfaces require a
minimum of 2 weeks curing; however, this may vary on the blend of asphalt
to aggregate. Improperly
blended or cured asphalt will not withstand the stress exerted by the
curing of the paint film
and, therefore, the areas striped may pull the asphalt loose. If there
is any doubt regarding this,
apply a small stripe of paint to an area and allow to cure. Observe the
results before striping the
entire area.
-
Fresh asphalt surfaces
have a tendency to bleed very badly when solvent based paint is applied.
If solvent based paint must be used, we recommend a thin coat (approximately
5 mils) be applied
on the surface, allowed to cure about a week, and then a regular coat
(15 mils) be applied as a final
stripe. Each individual user must decide the type of surface being coated
and the method to be
used. However, if possible, the user should consider waterborne coatings
for new or rich
asphalt surfaces and sealcoated surfaces, since they have less tendency
to bleed and will expand
better on new surfaces.
-
New concrete surfaces
are very difficult to adhere to due to their curing compounds. Most
curing compounds take 8 to 12 weeks to dissipate. Therefore, painting a
concrete
surface less than 3
months old is NOT RECOMMENDED. If painting must be done sooner, please
contact SAFETY
COATINGS, INC. for our recommended paint and application procedures.
-
All paint should be
stirred thoroughly before use. Thinning is not recommended; however,
if necessary,
no more than 2 quarts of solvent (as recommended by SAFETY COATINGS,
INC.) per 5 gallons
of paint (5 gallons per 55 gallon drum) should be added. Gasoline is
not recommended as a
thinner.
-
All paint should be
applied at 15 mils + 1 mil wet. The spreading rate is 350 linear feet
per gallon of
4-inch line.
-
For reflectorization,
drop-on glass beads should be applied immediately after the paint with
the
optimum amount being 6 lbs. per gallon of paint uniformly spread over
the entire line.
-
All paint lines should
be adequately protected until they are track free before traffic is
allowed over the line.
-
Since most traffic paint
dries rapidly, all equipment, tools, etc. should be cleaned as soon
as possible
after application is complete.
-
When applying alkyd
paints, the air temperature should be 40 degrees F minimum, and the
surface temperature 40 degrees F minimum. The application temperature of
heated
paints
should not exceed
150 degrees F.
