Our Oakum caulking is made with bentonite, an inorganic compound that expands over 10 times its volume when wet. It is clean from knots and yarns, is long stranded and has no lumps or ends of sacking. Twisted jute packing. Further improved with golden oils. Does not split.
Oakum is the best choice for caulking wide gaps in planking. For varied planking, keep some Caulk Wicking on hand for tight spots, and Caulking Cotton for medium-space gaps. Typically, on boat seams Oakum caulking is next covered by a marine paint. Once dry, the remaining space is filled with seam compound (one for above waterline, another for below) before applying final topcoat.
Available in boxes of 5 lbs.

Equine Farrier Industry likes to use Oakum to pack into the hoof or sole while the animal is recovering from an injury. The idea is considered "old school" but works very well. All farrier supply stores should offer Oakum. We sell it by the pound.

I bought this product to caulk the deck seams on an Historic wooden Schooner, as we were running low on the traditional oakum we had and wanted to make sure we would have enough to finish the job. This product, although probably perfectly fine for plumbing applications is not useful in traditional wooden boat building/restoration because it comes in such short 2 1/2 foot lengths. If you're looking for traditional oakum for caulking seams on a wooden boat, spend the extra money and get the real stuff.

I had a 4 inch pipe in my basement wall that carried the electrical wiring into my house. The plug that the contractor used to plug the hole failed. Being familiar with plumbing used the old cast iron I searched for Oakum as I was sure it would plug the hole. I filled the hole with oakum, packing in it tightly and then put a 1" layer of quickset expanding concrete to hold the oakum in place.

We use Oakum as a sealant for our hydro turbines. Seals dissimilar materials like cast iron, steel and concrete. It sets up and becomes a permanent repair.
