Narrative:
I accomplished a repair of the sound deadening material on the #2 engine in accordance with srm 54-00-01-2. When I applied the patch material, I applied the heat gun in accordance with srm due to below minimum outside air temperature. The patch had set up but was tacky. I proceeded to accomplish work on our other overnight aircraft. I then returned to the job and the patch was still tacky to touch. I again applied heat gun which did not help patch get any harder. Before going to other aircraft/workload, I will fill out a write-up made by technician for rechk to check repair at least 1 hour before shift change to check if patch has set up properly.
