TDS Teak Decking Systems caulk is a one-part, paste-like oxime cure system that forms a tough, flexible solid rubber compound when exposed to the air.
Used primarily for caulking teak boat decks, Teak Decking caulk is a thixotropic material that does not sag during cure, and has excellent temperature stability and chemical resistance once fully cured.
Because the sealant is neutral cure, it is non-corrosive to all substrates. Available in black, white, and gray.

Looking to bring some caulk during some extended cruising to fix teak seams as needed... Is there any product expiration date? Thanks.
I would cat TDS as I have in the past. They would be best to comment on their product. It only hardens up when it is exposed to air. I have used this over several days and keep the tube closed when not in use with a long screw.
Yes there is an expiration date, but if you dont open the cartridge it will last a long time. Opened up cartridges are getting hard 3_6 months. It is an excellent product, we redid all the teak seams with it. Easy to clean up as well but you need to tape off everything around the seams. Recommended.
None listed, but there is a manufacturing date. I bought mine 2 years ago.Last time I used it this past fall without issue. Keep away from heat orcold and you should be fine would be my guess.
what is the coverage rate?

I have a teak hatch cover and am going to apply a piece of 1/2" acrylic over the top of it. Would the teak deck seam calk work to glue them together and seal the water out? And would it cure properly? Thanks,Peter
Sikaflex 295UV would have better adhesive qualities.

I need to re-caulk my deck, the weather right now is over 100 degrees, should I wait until cooler weather maybe this fall or can I apply the caulk during evening hours and let it cure over night? During the day I still expect it to be somewhere between 90 and 100 degrees.
I would wait until the temperature of the deck is below 90 deg F. The product label says temperature needs to be between 40 and 90 deg F. If the deck temperature is above 90, especially in the tropics, it may cause the caulk to bubble out of the seam as you lay it down.
seams need to be clean and dry. after i caulk the seam i run my finger down the seam, use latex gloves. after the caulk cures a bit i run a putty knife down the seami like to tape both sides of the seams, makes clean up easier.

Great product. Have installed it in 90 to 100 degree summer heat. Flows nice and sets up just fine. Need to work fast or it glazes over quickly. Have had some installed for 5 years and it is holding up well.
I would refer to mfg. for answer
Hi I have recalled the teak decks on 2 yachts in summer in Georgia using this product. It went off too quick in the middle of the day so that time was used for preparation. ..it was in the 70's and early 80's so 100 degrees F will definitely be too hot. Early morning and late evening is best but you need a large fan pointing at you to keep the no-see-ums at bay!
I have a Grand Banks 46 classic .How much product will I require to complete this project?
Rod,That is a great question and the answer depends on how much caulking you plan on replacing. If you are only doing a small area, like I was, I used very little. If you are recaulking your the entire teak deck I would not venture a guess. I recommend that you call Teak Decking Systems in Florida and ask them the same question.Have a great holiday.tom little
I have a CHB 34 and I used 45 tubes I would think that you would be looking at around twice as much. A LOT Depends on how how thick the Teek on the deck is. Its a big job but worth the effort. Gary
This is a great product ! Obviously, you'll need several tubes, BUT, consider buying 1 tube, time the project's consumption of that tube, and then order a number of Teakdecking caulks to complete the next phase of work. It is time that limits your purchase. Some people will restore the deck in sections over a long period, BUT the Teakdecking caulk does not have a long shelf life. Open a tube, use it within two or three days. I have heard reports of Unopened tubes being wrapped in aluminum foil, refrigerated, or kept in a cool, dark space in order to extend shelf life. Knowing your work schedule will allow you to order fresh tubes and not be caught with a hardened un-opened caulk that has been sitting around neglected for a few months. This is the only teak deck caulk I use. It is great stuff!
Without more info impossible to answer your question. I did a Hudson 50 sailboat and used a lot, probably around 25 tubes. After two years of work and still more leaks than when I started I got rid of the teak. I tore up about $40,000 worth of tesk and put down a nice fiberglass deck. Painted it, striped it and No leaks!!! Looks great. I now have a functional boat where I can spend time cruising rather than working on teak decking.Hudson 50 Seute Deern Sailboat & crew.
Will this adhere to itself if doing spot repairs?
Yes, I believe it will. Provided that the original caulk is still in good condition that should be no problem.
Yes, just make sure to prep surrounding areas.
Yes. Great stuff.
Yes indeed, but its best if you slice away a bit of the original so that there is a fresh clean surface for bonding with the new TDS caulk. I use this technique when repairing caulk 'tear outs' and separations from thinned out teak deck strakes.
We had our deck done with this product 3 years ago, now in the high heat sun 100+ out, the seams are soft and tar like. tracks on your shoes, what is going on, the decks are cleaned with salt or fresh water only?
I am sorry I cannot. I am just redoing my deck now and have been happy with it thus far. I am in the San Francisco Bay Area so I don't see those kinds of temperatures. I have spoken with many people that are happy with it. If that is the case it raises real concerns since I am headed for the tropics. If you find an answer I'd be interested.
I don't know the answer. I had orignally redone my seams with the 2 part boat life caulk. I used this to do some touch ups only due to the reviews. I have a boat on fresh water. I coat with only a teak sealer -- but I have read that some of the materials used to coat the teak may react with the caulk and soften it. Are you using any coating materials on the caulk? I had problem with Sikkens, went to a different material; just to seal; but need to put on couple times a year.
We've had no such problem. We're at altitude of 6500 feet. Average temp. is 70 - 80 degrees in summer 60 at night. 10% humidity. Teak decking is sealed with Semco.
OK... so i see this is for teak decking... however, i have mahogany on the exterior of the bridge, and Cap rails on my 46' 1965 Chris Craft Constellation.. which will receive stain and varnish.....would this be a better product to use on the seams rather than the boat-life product for this application..??
TDS caulking is compounded to be sandable a few days after application. If you are sanding seams to get them nice and flush then TDS would be the way to go. I use it for gluing in polycarbonate windows to grp frames and polycarbonate renewal in aluminum hatch frames with good results. I still use 5200 or boatlife for deck fittings and of course silicone for plastic deck fittings. TDS works well for glueing down woods as well as caulking seams.
This is a great product, as it does not require a primer in the caulk joint. My concern would be the sequence you plan to install it. If you apply after varnish is there a bonding issue to any varnish that gets into the joint? or if applied prior to finish, what is the effect of the varnish that will come in contact with the sealant? This would be a concern no matter what product was being used. I would contact the Manufacture direct for some tech assistance on this one. Good luck.
Bob I have used both on my 1978 CHB but prefer tds. It dries quicker and is easier to spread I am not sure about adhesion of varnish my decks are all natural Dennis
Is teak decking system appropriate for topside hull seams in a wooden boat? Seams will be traditionally caulked with cotton then topped with 'rubber" and then painted with Interlux enamal. Thanks you
My gut tells me it may not be the best idea. To putty hull seams you should use a compound that is formulated for that purpose. This stuff is for teak deck seams. Also, I'm not sure this product will hold paint very well but you may want to contact the manufacturer about that. Plus there are less expensive compounds. No matter what you do, always prime the seams before you putty.
Don't know. Only used on tradition teak deck seams over fiberglass. Call TDS they are very helpful.
Great Stuff. Used to do deck on my 50' sailboat. Very easy to work with. Teak has to be sanded and clean to get good adhesion. I didn't used anything other than teak oil to do deck after sealing. Lasts about 2 years max. I don't think any enamal will stick to the rubber surface. If you paint it I think you will end up with a mess!!!
I have never tried to paint the caulk with enamel. I used the caulk with teak wood only without paint. Rest assured the caulk is really a good quality product. It doesn't get soft over time.
Don't know if appropriate for planking
I have a similar situation. I have a 37' wooden ketch with yellow cedar planking.I redid the seams last November, traditional cotton with the teak decking material on top. The hull is bright finished with Cetol Marine over the caulking. The boat has been in the water since, and I have not seen anything untoward happening. I do wonder about the Cetols retention over the teak for the long term, but so far it is working. I also did the deck, which is fir, and the cetol does come away in some of the heavy use areas such as in front of the companionway. I will post some results as time goes by. The boat is located in the west coast of BC so is exposed to the weather all winter.
Teak decking system caulk has been a great product to use over the last 7 years. I have only used it to rework seams in my teak decks which have held up well when applied correctly. Not sure you can paint over it but it does adhere well to the oily teak deck and seems to stand up well to temperature changes, -10 in Rhode Island winter to 110+ California Delta summers. I always keep a few tubes around to touch up my 30 year old teak deck. The product shelf life seems to be greater than stated.
Can this be used with Star Brite Tropical Teak oil? Also do you recommend taping the teak before applying the caulk? Over spill can be sanded off correct?
Hi Tabbetha,I'm pleased with the product. I don't use any finish on my teak decks. I think that defeats the purpose of teak, low maintenance non-skid. I taped off each seam. Most decks are 1 7/8" wide so two layers off 1" tape make it easy. I used the cheapest tape as it's going to need to be taken off almost immediately. If you wait too long the edges of the caulk lift. The caulk is pretty tenacious and if you don't mask, you'll have a lot of sanding to do and if the deck's not perfectly flat, and none of them are, you'll have to sand for more hours than it takes to do the masking.I suggest reefing a 2'X2' section. Masking it, caulking and smoothing it and then immediately lift the tape. I found I could peel the tape in towards the center from both ends and the sides and not make a mess.Good luck,Dennis
DR DENNIS WILCOXON
Yes, be sure to remove tape when caulk is still very pliable.
JUDITH LYNN MEISSEN
Can't answer the question about that particular teak oil. I used Semco after I calked my deck.I have tried taping and not taping. I tape small runs but do not tape long runs. Need to evaluate whether or not you think taping time is effective.Sanding the produce works fairly well. Use 80 grit as suggested and make sure it is fully dry.Cptned
Hi Tabbetha, I can't answer your question about Star Brite having never used it. I recommend masking the teak to minimize the black dust when sanding, just be sure to remove the tape before the caulking has dried completely or you may pull the caulk out of the grooves. Also you should put pin striping tape on the bottom of the groove so the caulk sticks to the sides and not the bottom causing it to separate from the sides during shrinkage. Hope this helps and good luck.
I dont oil Teak. For teak decks I seal with Semco.For filling teak deck, etc. grooves I carefully mask & tape before caulking and let the TDS rest for several hours and the pull the tape and allow the caulk to fully cure. I then use a very sharp chisel to 'plane' down the caulk to be flush with the teak, followed with a hand hand belt sander to clean any TDS that has embedded in the surface grain of the teak. The reason that level the caulk is to prevent any foot traffic from tearing the caulk loose from the sides of the grooves of teak deck strakes. I then bleach the deck with oxalic acid, rinse well and let dry. (After full drying, I then apply Semco (natural) ... just before nightfall so that the Semco has a longer penetration time into the teak for better and longer service life of the sealing. )
I can't answer the question about the teak oil as I never use oil on teak decks. I see no reason it wouldn't be compatible but I don't use oil on the decks as it just attracts dirt.I do not tape off the teak when using SIS440. I use a hooked scraper first and then sand. Works quite well.Jon DavisDavis Boat Works

Teak oil is not advised. Just attracts dirt. Don't use it. Absolutely yes to taping before caulking. If you don't you will have a huge mess. After it's dry(48 hours) you can sand it evenly.
I was recommended this product after having a bad result with a competing brand. This one works really well.
This comment is for the guy that thinks because they caulked hundreds of hotel rooms they know everything about caulking. Get a five gallon bucket, fill it with hot water, and drop the tubes to be applied into the water for 10 mins. The warmer the material the better it flows!
Captain caulks more
I would buy this product again
We caulked our deck with Teakdecking systems, it went on smooth and easy after a lot of prep work. The finished job looks great!
TDS Caulking, No more needs to be said!
As far as I'm concerned, TeakDecking Systems is the best deck caulking on the market today. The caring staff at TDS is rare these days. All others are trying to catch up!
San Francisco, California
I will buy again
Good price works well
Easy to use, works as advertised. I definitely would use it again.
Used it to do something unique in a bedroom. Appears very compatible with oak. Easy to use. Was lazy and used high speed grinder to remove excess caulk. Held together extremely well.
Great product very good price
I use this calk on my CT-41'sTeak decks and my three hatches, works great!

I like this product, works as advertized.
A little product leaks by the tube piston, solved the problem with a sandwich/snack bag over the caulking gun piston, otherwise product gets on the caulking gun feed mechanism.
This is what was recommended on forums for my teak deck and I'm not disappointed. JD has the best price I've found.
