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.

Can this be used for a teak to teak or a teak to gel oat seal? What type of prep need for teak? Assume unsealed and unvarnished teak the best? The reason I ask because on the package it says not for use on teak deck seams. Thanks
It can be used as a sealer, just be sure to clean well with acetone first.

Is this as good as 5200 fir below the water line thru hull's?
5200 setup up hard. This sealer stays flexable when cured. Haven't had any problems above the water line. Have used it below water line and it didn't seem to affect it one way or the other. Think' silicon sealer a little more flexable'. Be used it for everything.
AS far as I know, the total boat seal is holding up. I applied 5 tubes on my deck replacement. I certainly hope it is as good as 3m 5200.
No I would still use 5200 below the waterline. I like the Total Boat sealant for hatch mounting and general caulking outside as it doesn't yellow like 5200 and is much easier to work with and remove parts when needed.Brett S/V Seismic Wave
Hello - Can this product be used as a light adhesive? I'm mounting some gear hammocks inside my boat and want something that has adhesive properties, but can be removed later, if I decide to move things around.Thanks in advance!
Hi Michelle, I think this product would work, it's pretty tenacious after it dries. A word of warning it can be messy, I would tape around the area and be diligent. Read the label it takes a day or so for complete cure. I would take a couple of those little silicone bumpers (like for the back of cabinet doors)cut them if you need to make them smaller and put them between the parts that you are gluing at act as space to make sure you have enough caulk between the parts. it keeps the caulk from squishing out... Good luck,
This is for gluing plastics and such - there are better stuff - like 4200 - not the 5200 too strong.
Very versatile product. I have not used it for that purpose.Seems like you might have a problem with clamping until setup.
what is the prep for using as a seal on fiberglass. There is old caulk in the joint. After I dig it out will Acetone be a good choice?
Use a scrapper or knive blade to remove the old caulk. Any number of solvents may work to remove caulk residue. Can't say for sure not know the typed of caulk.
Thanks for your feedback
Is this good for deck joints on fiberglass or is silicone better?
This is a good product on fiberglass deck joints. Do not use silicone, it will fail.
Can this be used to bed lexan port lights?
Use Lexel Sealant for Lexan. Brand name: LEXEL
What type of sealant is this? Polyurathane, polysulfide, Polyether, silicone, something else? It should specify in the product description since no product is appropriate for all situations or all substrates.
Elastomer refers to the group of rubber like polymers. Polysulfide is an elastomer but all elastomers are not polysulfides. Look for the registered trade name Thiokol.
This is an Elastomeric (Synthetic Rubber), not a Polyurathane, polysulfide, Polyether or Silicone.
anyone use this product to seal starboard? Does it work?All the literature I saw about starboard is that no common adhesives stick to it.
I used this product to attach neoprene rubber to the bottom of my new Moeller fuel tanks. I hear that not much will make a bond with starboard.
Thanks Dennis, I asked the question because the description says it adheres to starboard. I guess that's not accurate.
Yes I have used if to seal starboard - it will stick only as a sealant not as an adhesive. And it can make a compression seal between two pieces screwed together. I also use dolphonite to install starboard as a backing plate for mefal hardware. I use the nonskid starboard to make backing plates. Use 1/2" starboard with the nonskid facing the surface which gives the sealant or the dolphonite a place to reside between the surfaces when the antenna mount of horn or whatever is tightened down.I only use the sealant on fiberglass boats or on Triumph extruded plastic type boats and dolphonite on wood painted boats. Dolphonite won't rip the painted surface if the hardware and starboard plate are removed someday.
Does this get hard in the tube quickly after opening? Can it be capped remain usable for at least 3 months? What is the tack free time?
I use a caulking tube insert from home depot and i keep the opened tube in my freezer -- if you docthis it will still be useable six months later.
Sorry, but I have not used the product yet. Tube is still unopened.
This is a quality durable sealer
I sealed two access ports In a 470
Very misleading. Picture is wrong for the default size.
What arrived was a squeeze tube. What is pictured is a cartridge for a caulking gun. Bait and switch.
Love this sealer!
I have used many tubes off SEAL and will keep using all over the boat and in the bathroom at home! Great stuff!
Torres del Paine, Chile.
would buy again,in fact i did
good sealant,dries really fast
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!
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.
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.
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.
