Boat Bottom Rot Repair Old Time World - Howard Johnson Jr Blogs 0 This lovely Whirlwind was restored ten years ago but was accidently left with water sitting inside for a long period of time. Rot developed in the keel and hull on both sides. I decided to do a simple repair. First I sanded the finish off and down to solid wood.It’s a 1955 14 ft model. I saturated the rot areas with West System Epoxy.Then I made reinforcement marine plywood for both sides and bedded them in epoxy putty. I added fillets of PL500 Construction Adhesive.With the boat turned over the outer keel was removed and all the soft areas were sanded on the outsideThis is what it looked like before sanding. At this point Cheryl washed the bottom of the boatSanding back to good wood with an 8 inch 40 grit disc exposed the penetrations from the other side, now this side was penetrated with the thin West System EpoxyNext a blob of 2 part of epoxy putty is mixed. I clamp the mixing board to table because it is so thickPutting the putty in placeNeatly spreading to fill all the holes and cavities. Several applications were requiredThe belt sander helped to produce a smooth flat finish.After sanding with the disc, I sanded with a belt sander. The outer keel was fitted and screw holes drilled. Then the keel was installed using the same putty adhesive Rot Repair
