Curing Time

Without 44-710

| Temperature †|| To Touch || To Handle || To Topcoat |
| 75°F (24°C) || ¼ hour || 1 ½ hours || 16 hours |
| 65°F (18°C) || ¼ hour || 2 ¾ hours || 16 hours |
| 55°F (13°C) || ¼ hour || 5 hours || 20 hours |
---† 50% Relative Humidity. Note: Refer to product listings on for specific potable water return to service information. Curing time will vary with surface temperature, humidity, and film thickness. Note: When recoating Series 1 with itself, the minimum recoat time is 2 hours at 70°F (21°C).
Ventilation: When used in enclosed areas, provide adequate ventilation during application and cure.

With 44-710: The use of 44-710 can greatly reduce dry to handle cure times. Note: Series 44-710 Accelerator must be used when the surface temperature falls below 50°F (10°C).
