Listed below are general equipment guidelines for the application of this product. Job site conditions may require modifications
to these guidelines to achieve the desired results.
Multiple coats may be required to obtain desired appearance, recommended dry film thickness and
Brush & Roller adequate hiding. Avoid excessive re-brushing or re-rolling. For best results, tie-in within 10 minutes
(General) at 75°F (24°C). Typical thinner addition rate is 12% but allows up to 20% with Thinner 33 by volume
per gallon. Use a short-nap synthetic roller cover with phenolic solvent resistant core.

CURING SCHEDULE
Dry to Topcoat w/
Surface Temp. Dry to Handle Maximum Topcoat Time
Other Finishes
20°F (-7°C) 16 Hours 24 Hours 1 Year
68°F (20°C) 4 Hours 5 Hours 1 Year
These times are base on 50% relative humidity. Higher film thickness, insufficient ventilation or cooler temperatures will require
longer cure times and could result in solvent entrapment and premature failure. Excessive humidity or condensation on the surface
during curing can interfere with the cure, can cause discoloration and may result in a surface haze. Any haze or blush must be
removed by water washing before recoating. During high humidity conditions, it is recommended that the application be done while
temperatures are increasing. If the maximum recoat times have been exceeded, the surface must be abraded by sweep blasting
or sanding prior to the application of additional coats. Note that exposure to direct sunlight will drastically shorten the maximum
topcoat time.
CLEANUP & SAFETY
Use Thinner #2 or Acetone. In case of spillage, absorb and dispose of in accordance with local
Cleanup
applicable regulations.
Read and follow all caution statements on this product data sheet and on the SDS for this product.
Safety Employ normal safety precautions. Use adequate ventilation. Keep container closed when not in
use.
When used as in enclosed areas, thorough air circulation must be used during and after application
until the coating is cured. The ventilation system should be capable of preventing the solvent vapor
Ventilation concentration from reaching the lower explosion limit for the solvents used. User should test and
monitor exposure levels to insure all personnel are below guidelines. If not sure or if not able to
monitor levels, use MSHA/NIOSH approved supplied air respirator.
This product contains flammable solvents. Keep away from sparks and open flames. All electrical
equipment and installations should be made and grounded in accordance with the National Electric
Caution
Code. In areas where explosion hazards exist, workers should be required to use non-ferrous tools
and wear conductive and non-sparking shoes.
