Refer to the MSDS sheet before use.
Published technical data and instructions are subject to change
without notice. Contact your Sherwin-Williams representative
for additional technical data and instructions.
Surface preparation must be completed as indicated.
Mix contents of each component thoroughly with power agita-
tion. Make certain no pigment remains on the bottom of the
can. Then combine one part by volume of Part A with one part
by volume of Part B. Thoroughly agitate the mixture with power
agitation. Allow the material to sweat-in as indicated prior to
application. Re-stir before using.
If reducer solvent is used, add only after both components
have been thoroughly mixed, after sweat-in.
Apply paint to the recommended film thickness and spreading
rate as indicated below:
Recommended Spreading Rate per coat:
Wet mils: 7.0 - 13.5
Dry mils: 5.0 - 10.0*
Coverage: 116 - 232 sq ft/gal approximate
NOTE: Brush or roll application may require multiple coats to achieve
maximum film thickness and uniformity of appearance.
* See Recommended Systems
Drying Schedule @ 7.0 mils wet and 50% RH:
@ 40°F @ 77°F @ 100°F
To touch: 4-5 hours 2 hours 1½ hours
To handle: 48 hours 8 hours 4½ hours
To recoat:
minimum: 48 hours 8 hours 4½ hours
maximum: 1 year 1 year 1 year
Cure for
service: 10 days 7 days 4 days
immersion: 14 days 7 days 4 days
If maximum recoat time is exceeded, abrade surface before recoating.
Drying time is temperature, humidity and film thickness dependent.
Pot Life: 10 hours 4 hours 2 hours
Sweat-in-time: 30 minutes 30 minutes 15 minutes
Application of coating above maximum or below minimum rec-
ommended spreading rate may adversely affect coating per-
formance.
Stripe coat all crevices, welds, and sharp angles to prevent
early failure in these areas.
When using spray application, use a 50% overlap with each
pass of the gun to avoid holidays, bare areas, and pinholes. If
necessary, cross spray at a right angle
Spreading rates are calculated on volume solids and do not
include an application loss factor due to surface profile, rough-
ness or porosity of the surface, skill and technique of the ap-
plicator, method of application, various surface irregularities,
material lost during mixing, spillage, overthinning, climatic con-
ditions, and excessive film build.
Excessive reduction of material can affect film build, appear-
ance, and adhesion.
Do not mix previously catalyzed material with new.
Do not apply the material beyond recommended pot life.
In order to avoid blockage of spray equipment, clean equip-
ment before use or before periods of extended downtime with
Reducer R7K15. In California use Reducer R7K111.
Tinting is not recommended for immersion service.
Use only Mil White and Black for immersion service.
Quik-Kick Epoxy Accelerator is acceptable for use. See data
page 4.99 for details.
Refer to Product Information sheet for additional performance
characteristics and properties.

Clean spills and spatters immediately with Reducer R7K15.
Clean tools immediately after use with Reducer R7K15. In
California use Reducer R7K111. Follow manufacturer's safety
recommendations when using any solvent.
