TotalBoat Seal Elastomeric Marine Sealant

TotalBoat Seal is a fast-curing elastomeric marine sealant that adheres tenaciously to fiberglass, wood, metal, glass, Starboard & vinyl. It creates a highly elastic waterproof seal ideal for bedding hardware, windshields, and portholes, as well as flush & overlapping joints. Once cured, Seal is paintable and sandable.

Seal is highly UV stable and will not sag on vertical surfaces. It boasts superior properties over most leading sealants including strength, adhesion, elongation, and shelf life. For use above and below the waterline. Do not use on wood deck seams.

Available in White only. Choose from a 3 oz. tube, 10 oz. cartridge, or 6-pack of 10 oz. cartridges. Cartridges fit standard 290ml caulk guns.

Important: TotalBoat Seal is designed for bedding and sealing, and does not have the strength properties of bonding adhesives.

TotalBoat sealant is my sealant caulking of choice.


I use this product almost as much as epoxy resins on a variety of applications from joints to porthole. It applies well but don't let it get away from you on a cosmetic required piece of work. You make have elastomeric strings where you don't want them. I find it a very versatile product. As a matter of fact, I need to order another couple of tubes!


Montross, Va.




I just used it so its long term efficacy is unknown. One oddity I noted is the tube is oversize for my caulking gun. I had to bend the front outward to squeeze the tube into the gun.




Good Solution


I used TotalBoat Seal on a Bevins skiff that I'm restoring. It applies easily and cleans up well. The seal seems good and it filled the frame to plank gaps easily, cleaning up the interior of the boat.


Portland, OR


Just OK


Sets up very fast, almost too fast. One of the cardboard tubes punctured when stressed unlike what a metal or plastic tube would do.

Ask me next year


The products skins very fast, nothing will work for clean up other than the recommended mineral spirits. I replaced the chainplates and recored the area around it, I layed down a medium to large bead of the sealer arround the chainplates to temp seal them until I installed the closeout covers the next weekend. The sealer received one week of hot Florida sun before the next weekend when I installed the close outs. The sealer was still soft and peeled of rather easy, very strange. I am not sure about this product yet, ask me next year.

I started using Totalboat sealant last year on my clapboards on my 225 year old cape house.. I just finished using it as the sealant on two neo angle shower frames.

A good product for the price


I was using this for various tasks repairing a Chris Craft Constellation. The caulk comes out smooth, it doesn't seem to magically get all over you like 5200 seems to do at least when I use it. It takes longer to cure. My biggest complaint is that the nozzle is not attached well to the cartridge. I've had two of them break off at the base causing me to waste about a tube of caulk total. I have not addressed this with Jamestown yet but I plan to. Don't put too much pressure on the nozzle when you are running down the seam or you might have the same problem.

Paintable water tight seal on vinyl


I needed a water tight seal around vinyl windows on my house. Weather here ranges from subzero to 100+ so I needed a sealant that would not crack or pull away with expansion and contraction of siding. The Total boat elastomeric was easy to apply, cleanup was simple, and I had no problem with caulk setting up in the nozzle when left for a couple of days (used a simple nozzle seal). After a couple hours the caulk was nicely cured.

Good product


I used this sealant between our cockpit coming and our teak seats. It applied easily, dried quickly and seems to provide an excellent seal
