(1)  Maintain the temperature of the repair at 20 to 25 °C (68 to 77 °F) for at least 24 hours to pre-cure the repair.  If you do not have an oven or a warming room you can make a temporary enclosure around the repair to trap the heat from a flame proof air heater. 
CAUTION: DO NOT ALLOW A TOO HIGH TEMPERATURE DURING THE CURE. A TOO HIGH TEMPERATURE CAN DAMAGE THE COMPOSITE STRUCTURE. 
(2)  After 24 hours raise the temperature of the repair to at least 65 °C (149 °F) for a minimum of 6 hours to complete the first stage of the post-cure.  Monitor the temperature every 15 minutes for the first hour and then hourly. 
(3)  After a minimum of 6 hours raise the temperature of the repair to at least 80 °C (176 °F). Maintain this temperature for a minimum of 14 hours to complete the final post-cure.  The final stage post-cure time can be divided into sections but you must make sure that the repair has a minimum total of 14 hours at post-cure temperature.
