TotalBoat Seal is a fast-curing elastomeric marine sealant that adheres tenaciously to fiberglass, wood, metal, glass, Starboard & vinyl. It provides a highly elastic waterproof seal ideal for bedding hardware, windshields, and portholes as well as flush & overlapping joints.
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. Paintable and sandable. Easy cleanup with mineral spirits. Not for 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,
Can this sealant be used on a coachroof window (port light)? My water leaks are probably due to flexing over the years. How long can I work with the sealant before putting the window back in place? My boat is a Beneteau 423. The edge 23-24 linear feet. Would take some time to get a good bead down.Bob D. s/v Ruach Richmond, VA
Very good product but was very slow curing for me. Took about 4 days to completely dry.Easy going on and I used a pop stick to smooth out the joint.I used it to seal the deck on my 25' columbia northsider. Help this helps.
We have used this in places where several tubes were required before joining. I would comfortably say you have 5 - 10 minutes open time, longer depending on temperature. Storing the tubes in a cool place before application may give a bit more open time.
Probably olay but this stuff is geared toward sticking to plastics and such and most people use 5200 on portlights - i would probably use 4200 which isnt as sticky- you might want to remove it someday.The problem with all these curing type sealants is that if the bond gives up - then they will leak. I use dolphonite for my own portlights - lots of it - and let it squish out all around. Dolphonite doesn't ever harden and it flexes and moves with the boat and portlight or other hardware that is being bedded. And don't tighten the screws too much - just until it is snug and dolphonite is squishing out all around- apply lots of it. Wait overnight for the excess to skin over a little and then use a plastic caulking blade to remove it - you can tape around the portlight of course but the dolphnite wont stick to the areas around the portlight- it will clean up easily- use a little solvent in a rag to do the last big of clean up. Much friendlier stuff than a curing caulk adhesive.The portlight is held in place by the screws all around the frame - ao you don't need an adhesive - you need something that will keep water from penetrating past the frame- with dolphonite you can tighten the screws again a week later and a little more will likely squidh out but you dont want to tighten down the screws and push all the dolphonite out. Also two years from now if it leaks you can tighten the screws again and the dolphonite will squish out With the cured caulk - despite what some guys say- if you let the caulk harden and then crank down the screws the caulk can pull away from the boat or the metal frame and create a path for h2oAny of this caulk will work somewhat - but Personally I like dolphonite - for this type of installation - it is a true mositure caulk and not an adhesive which is not necessary to hold the port light in place.Just my two cents - I installed three bronze portlights on my wood 71' 32' grand banks eight years ago and no leaks yet!
Hi Bob,Yes it can be used on a port light I installed four and is working well, this stuff sticks like crazy.1. it skims up in VERY short time, work fast! I used the little cabinet door stop buttons, you know those rubber/silicone things they put on kitchen cabinet doors that keep them from banging shut, placing a couple them around the rim/flange. That way you can just snug the fasteners and not squeeze out all the sealant. in a few days give them another little turn. You can slow down the curing/skimming time by keeping the sealant cool, work early in the morning, it really skims fast.
Dear StaffJamestown's ad Says above and below waterline, However tube says only Above! Which is it?????
I used it to caulk windows. I only use 5200 below the waterline.
CAPT. HANK JACKSON
No better than it adheres, I'll only use it above the waterline. After a week curing, it was more like a silcone than an adhesive.
I have only used it above waterline and happy with it. I would go with a product made for below waterline only. But that is just me.
I bought a tube to rebed some ports but haven't used it yet. However, I would be cautious about using anything questionable below the waterline, stick with 5200 or something made for underwater use.
depends on what you are using it for- if you fill holes and then cover it probablu y fine. Mostly no company wants to say it is good to use underwater- too much liability if it fails. For gluing stuff underwster I think 52000 says it is okay- but read their literature and call the manufacturer direct.This stuff is likely okay for sealing hardwsre underwater but all the yards seem to use 5200 as it cures underwater - even though you dont need an adhesive around a seacock that is sttached to the hull by threads -- so 5200 is really overkill.Making sure rhe surfaces are very clean - slighlty abraded and wiped with alcohol to remove any oils or the like - is important to successful sticking of any caulk ot adhesive.Making
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.
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.
Seaside Heights NJ
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 .
Rochester New York
Will continue to use.
I used this for bedding various deck fittings. Therefore have used it in small amounts. It has not hardened in the tube as some sealants do after you open them. This is good for my use as I can use small amts. repeatedly at different times. As above, it would be nice to have a cap for the end of the tube.
