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.

will white total seal stick to a varnished plywood floor for waterproofing above waterline?
Yes, be sure to clean and sand with 220 grit first.

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?
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
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.
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.
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!
Very versatile product. I have not used it for that purpose.Seems like you might have a problem with clamping until setup.
This is for gluing plastics and such - there are better stuff - like 4200 - not the 5200 too strong.
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,
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?
Thanks for your feedback
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.
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.
This is an Elastomeric (Synthetic Rubber), not a Polyurathane, polysulfide, Polyether or Silicone.
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.
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.
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.
Thanks Dennis, I asked the question because the description says it adheres to starboard. I guess that's not accurate.
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.
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?
Sorry, but I have not used the product yet. Tube is still unopened.
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.
Ease of application
The ideal sealant to keep on hand. Used topside on varnished teak, stanchions, chainplates, and fiberglass. Applies easily, tools well, forms a nice bead... and one year after purchase, what's left in the tube is still usable with absolutely no special precautions taken. Shorter cure time than traditional polysulfides. 3M 4000UV (competitor) cures in the tube once opened, and is viscous enough that it works best with a caulking gun. If you don't need a specialty product, keep a 3oz tube of this on hand for all general use.
I have used several tubes of this
It applies more easily than some other products I have used. It seems a little thinner. It seems to also takes a lot longer to cure completely. Mine stayed tacky for several days. It made a good seal but was pretty easy to peel off the excess from teak leaving me wondering if it is going to maintain a seal or have the tensile strength it states on the tube.
Seems to work very well as a sealant
Needed to replace some old sealant that was letting rain water in. Cleaned out the old stuff well before applying this material and this stuff bonded well to the fiberglass and PVC material I needed to seal around. So far so good, no more leaks..
Installed 16 new portholes using this product and it was perfect for the job. I'll be using it to bed and waterproof all the stanchions, thru hulls and other hardware as needed. Great intermediate caulking if you don't want the absolute permanence of a 5200 caulk.
Very good Adhesive Sealant
We have been very successful using Total Boat Sealant wherever 3M 5200 would be used.

Seal for starboard ice box
Use to create watertight joints on custom made starboard ice chest for a restaurant. Joinery was done with 3M 2part adhesive and SS screws. This made it watertight. I did let it cure for 7 days and seemed to get more strength each day
TotalBoat on a Citroen
Squirted sealant between rubber seal and roof. Will also squirt it between rubber seal and roof rail to completely protect roof and roof rail.
Saint David AZ
Fast drying time.
I used this to seal a leaky rub rail. It seem to dry very fast. Not sure how it will hold up longevity wise but time will tell. The price was much better then 3M product and seem to be very comparable.
Barry Ping "PingMarineCanvas"
very happy with TotalBoat products
makes a nicer bead than other manufacturers products. Doesn't harden in the tube so less waste.
description doesn't match the packaging
I have not used this product yet . The technical specs indicate it can be used below the waterline. however it's clearly printed on the tube that it's for above the waterline only. so I guess I'm saving it to use above the waterline when I get to that point .
