Subject: Stringer Repair: Polyurethane foam used to block holes prior to the application of L&L Resin
Date: May 21, 2006
I have completed the stringer repair and it went quite well. I would like to thank you for the fine
product and the advice as I went along. I do have a little procedure trick I tried, as the limber holes
kept seeping, and I was getting tired of losing the layup into the bilge. I tried several things to stop
the weeping, but was losing the battle. I finally took a can of spray foam, and sprayed it under the holes
and went home. The next day the holes were completely sealed, and I was able to continue right to the end.
Just took a drywall saw and reopened the limber area. I am attaching a couple more pictures of the caps back
on. I will have some more clean-up and painting, then out to sea!
Pictures (right) show the foam blockage of the limber holes along with drilled holes in top of stringers where CPES, Layup & Laminating Resin, and L&L Resin mixed with sawdust were pumped in.
