Curing Time

Temperature Maximum Recoat Time To Place in Service
75°F (24°C) 24 hours 24 hours

Curing time varies with surface temperature, air movement, humidity and film thickness.
Ventilation: When spray-applied, provide adequate ventilation during application and cure. Reference ventilation guidelines contained in the latest edition of AWWA D 102. Note: If Series 201 is used as the primer for a mortar system, the mortar application should take place while the Series 201 is still tacky, typically up to four hours, otherwise, aggregate should be lightly broadcast into the primer so to provide tooth to hold the mortar in place when spread. When the Series 201 is used as a vertical or horizontal primer for a thin film system, the 201 should be allowed to dry hard without exceeding the 24 hour recoat window. If Series 201 is used as the primer for the Series 270 Stranlok system, the Series 201 should be allowed to tack up for approximately one to four hours depending upon temperature but not allowed to dry hard.
