At 20 deg. C, DRY FLEX® 16 will cure in 16 hours, DRY FLEX® 4 will cure in 4 hours and DRY FLEX® 1 will cure in 1 hour. The products will then be ready for sanding and painting. At lower temperatures the curing time will be extended. The repair will fully through cure after approximately 7 days. At higher temperatures the pot-life (the time in which you have to use the product after mixing) will be reduced. In extreme conditions (working at above 30 deg. C in full sun with DRY FLEX® 4 or 16), there is a risk of the product not performing as well once cured.
