Marine-Tex is a high strength epoxy putty that hardens like steel and is sandable like wood. Use it to repair holes, cracks, dents, worn out surfaces and damaged substrates on your boat and beyond. This unique putty bonds and fuses ceramics, fiberglass, plastics, wood, metals, ferro-cement and porcelain.
Marine Tex epoxy is impervious to oil, fuel, grease, brine and detergents. Commonly used for minor fiberglass gelcoat repairs, tt is unaffected by temperatures from -60 F to 300 F. It can be sanded, drilled, sawed, threaded and painted. Non-magnetic, non-rusting and non-corrosive.
Note: Not suitable for use with polyethylene and polypropylene based plastics. Poor adhesion will result if surfaces are unclean, oily, greasy, or generally contaminated.
Choose stiffer Gray Marine-Tex for machinery and metal repairs, as White is better for fiberglass repairs.

Frequently Asked Questions and additional information
Underwater application: While Marine Tex putty can be applied underwater, it is likely to be washed away before it can cure. FlexSet is better for underwater applications due to its denser consistency. To test underwater application, mix the epoxy above water, and deposit on wax paper or plastic wrap. Slide the wax paper or plastic wrap onto the palm of your hand with epoxy facing up.
Take it below the water line and apply to surface. Be careful not to smack or pancake the product onto the surface, this will trap water under the epoxy. Instead, roll the epoxy onto the repair to push water out of the way. Leave wax paper/plastic wrap on the repair while full cure takes place for best results.
Below-the-water-line applications: It can be used for repairing gouges or holes located below the water-line. Once cured, Marine-Tex is impervious to water and many chemicals. The key is to apply in dry conditions, such as with the boat out of the water. Since putties will go only where they are placed, be sure that the Marine Tex has completely encapsulated the problem area. It is a good idea to sand the perimeter of the repair before application for maximum adhesion.
Will it cure in cold weather? Epoxies need heat in order to cure. If your application temperature is not at least 60F you must apply heat to the area before, during, and after the application in order for it to cure. ITW recommends you place a shop lamp approximately 12" - 18" in front of the application. The lamp will provide heat at a constant rate, so that the material's temperature is always constant. Do not apply a heat gun or hair dryer to the area, these types of heat will heat the area too much.
Once fully cured, it may be drilled and tapped once. Do not attempt until full cure has occurred. Marine Tex is fuel resistant (gasoline, diesel) and is suitable for repairs where fuel exposure is possible. It can also be used for gelcoat repairs. We are sometimes asked if it suitable for potable water system repairs, and the answer is no.
Temperature range limitations: While Marine Tex can safely tolerate 250F constant temperatures in a dry environment (with spikes to 325F), limits also depend on pressure and conditions.
How high of a temperature can Marine-Tex withstand? Temperature limits depend on pressure and conditions. Up to 250F constant temperature in a dry environment, with spikes up to 300-325F.
Adding Pigments: White Marine-Tex can be pigmented. No pure color will be achieved by adding pigments. (We recommend epoxy-friendly pigments, like Fibre-Glass Evercoat's.) Do not use more than 5% pigment per total volume of epoxy.
Gray Marine-Tex does not contain metal fillers. Both Gray and White have two year shelf lives in closed containers at moderate temperatures. Wen working with this epoxy putty, expect a pot life of approximately 30 minutes at 72 F. Do *not* use any thinners under any circumstances, as thinners change the physical properties.

Questions & Answers about Marine-Tex Epoxy:
2013-04-09SAL MUSCO asked: what is the cure time ????
2013-04-08A shopper asked: I am fixing a below waterline area about 8 inches around were i had core damage. I have made several small holes in this area to allow it to dry out over the winter. I would like to apply a product like marine-tex to fill and fair. two questions should I wet out the area with an epoxy like west before filling? And can I barrier coat over this patched area?
+Expand Answers
2013-04-11DAVID W JAFFIN: You should use Marine-tex directly on the area to be repaired - make certain that it's dry and clean. After it's cured, you can put anything on top of it
2013-03-26A shopper asked: Can Marine Tex be used to fill a small 1/4" x 1" hole in the bottom of my dinghy? If not, what should I use? Thanks
+Expand Answers
2013-03-27IAN BRUCE: I feel that a proper answer needs far more information before answering.
Regards,
2013-03-27Joe kiehm: Yes it can. It's kinda like bondo. You have to let it get to a "puddy" like consistency and it will harden like a rock!!. I would scuff up the edges around the hole just like you would if you were using an epoxy resin, you don't want it to pop out. Good luck.
Joe
2013-03-28FRANK GREEN: I'd use it as a finish, but there are better products to fill holes. A one-inch hole is pretty big -- Jamestown tech guys should be able to advise you.
Good luck with it.
2013-03-28RAYMOND PELLETIER: Hello Jamestown;
I could not reply to your question in the suggested area so I will respond here:
I was an earospace engineer for twenty three years, one of my responsibilities was bonding materials. The only problem with marine-tex is it has no self cleaning capacity, so the bonding surface has to be cleaned, usually by abrading just prior to application of the bonding material, and no skin contact is allowed to contaminate it. Other than that I have never seen this material fail. Also I have never found any better bonding material.
Respectfully
Ray Pelletier
2013-03-29CHARLENE BRADEN: I'm not sure. I only patched some little holes in the bottom of my pontoon on my hseboat that was in the water & it held up. Maybe you should put a little pc of something over the bigger part of the hole & then put this on top of it covering the corners really well. You didn't say what the dingy is made out of. If it is metal then put a pc of metal over the hole & patch it w/this stuff.
2012-12-27A shopper asked: how much does it shrink?
+Expand Answers
2012-12-27TIM APOLLO: The shrinkage on this process is minimal to the point you cannot notice it. I have used on both large and small areas with no issues
2012-12-27YOCHANON STEIN: I use on aluminum rowboats and canoes used at summer camp to rrepair small cracks and hols and does not shrink much from application over time.
It is a good product.
2012-12-27DAVID W JAFFIN: minimal, if at all
2012-12-27FRANK GREEN: I've used this epoxy as finish on two exterior doors that face strong weather. No shrinkage. Great product for exterior doors. I'd do it again.
2012-12-16A shopper asked: how long is the total cure time ?
+Expand Answers
2012-12-17MEL BUCKLEY: Cure time is influenced by temp and mixing proportions. If you follow the instructions and measure carefully it should cure in an hour or less to touch but give it four or more to sand and work.
2012-12-17DEREK PAGE: According the the box the total cure time is 12-16 hours.
I have used this product a lot and find that cure time really depends on the weather.
Leave this our in the sun 80 degrees F and it will be hard to touch in about 2 hours.
Even if it is not in the sun and the temperature is 60-75 degree F you should be able to start sanding in 4-6 hours.
I usually start sanding when it is hard to the touch. I test this by taking a butter knife and scraping it to make sure it does not have any putty (playdoughness) to it.
With that in mind. This is still the best product on the market for this... I wont use anything else.
I goes on like butter and hardens like steal. Even if you wait the full 16 hours for it to cure its still much earlier to sand then competitor products.
Hope this helps.
2012-12-17MARGARET C HENDERSON: I think it depends how thick an application you are making. But in general I allow 24 hours. This means it is thoroughly dry before sanding.
2012-12-18Joe kiehm: Hello,
I believe they want 24hrs. of cure time before it can get wet. Depending on how you mix it and work it, it'll take about 15min. to get to the "puddy' stage. That's about all I know.
2012-12-24CHARLENE BRADEN: We put this on under water on some pontoons in the water on our hseboat. IT was summertime but the water was maybe 70 & it cured pretty fast. I would think the warmer the weather the sooner it will cure. It doesn't seem to take a lot of time to cure.
2012-12-01C PHILLIPS asked: how deep can you build this stuff? Like how deep of a gouge in fiberglass can you fill? 1/4 inch, 1/2 inch....etc..?

2012-12-04Nathan Fournier: Yes, you can go 1/2 or deeper, I would do it in 1/4 or thinner layers at a time so it can cure properly, thank you.

2012-09-03JOSEPH KOPCHAK asked: how would it adhere to aluminum? the transome on my aluminum boat has some surface pitting . I plan in removing the paint, hitting the alumnum lightely with a grinder to scratch for adhesion than coat the entire transom with marine tex. From there I will work the marine tex smooth, feather edge, prime and paint with two component urethane enamel. your opinion would be greatly appreciated. Thank You Joe K.

2012-09-05DAVID JOSEPH: It adheres very well, I used it to fix a gash in my Grumman Sportboat.
2012-09-05RHONDA BURLESON: Marine Tex will be excellent to make your repair ,it works very well on aluminum,no need to grind alot of the surface,80 grit wet or dry on a jitterbug or vibrating sander will be fine!Hope this helps you,I use it for all kinds of repairs!
2012-09-05DAVID W JAFFIN: I have had limited experience with Marine-Tex adhesion to aluminum, but the few times I've tried it, adhesion has been good.
2012-09-05RAYMOND PELLETIER: It sounds like you have a good plan. I have been using versions of this epoxy for years both at home and in the aerospace field wher I worked, with never a failure.
2012-09-06RICH TOLWAY: My opinion is it will work. The stuff is very strong.

2012-08-28STEVE W asked: how much area does one 2oz. bottle of marine tex putty cover in sq. footage?
+Expand Answers
2012-08-31Joe kiehm: This is great stuff. I made the mistake of not letting it set-up and started using it right away. So, first of all, let it set up unless you are using it on a flat surface, then you can work it right away, but what on a boat is really flat? It will start to run on the slightest angle. Anyhow, getting back to your question, the 2oz. will give you close to 2sqft. at about 1/8"-1/4" thickness. I used it to secure a round electronic device (anenometer) in a square hole. Why drill another hole in the boat when you can use one already cut. Just get some Marine-Tex and some sand paper and she looks beauty. That's another thing, it sands like drywall.......VERY fine dust. I think you will be very happy with this product. Even though I didn't use it properly (i.e. not letting it set up to puddy consistancy) I was very happy with the results. Good luck
Sincerely,
Joe

I made an Intake Manifold for a Chevy 3100 V6 Engine, Modifying it from fuel-injection to carburetion. So Multiple Fuels could be used. The Grey Marine Tex worked perfectlly, and is also imperveous to gasoline. This is the 6th time I have ordered Marine Tex for similiar projects on Engines. and I will be ordering more for projects in the near future.

Comments about Marine Tex Marine-Tex Epoxy:
The swim platform on my 22 ft Stinray was pulled off while someone was boarding. I thought I was in trouble until I stumbled on to Marine Tex at a boating store. The screws had pulled out of the swim platform and took fiberglass with them. It looked terrible. I tried the marine tex and at first thought I was in trouble because it looked too creamy when mixed. Curing seem to be slow but the next day when I checked my repair it was hard as a rock but I was still able to sand. The repair came out excellant. GREAT PRODUCT !

Comments about Marine Tex Marine-Tex Epoxy:
I am refurbishing a twenty year old wooden drift boat, and needed to replace fiberglass/and epoxy putty that had delaminated where the bottom and sides met inside the boat. I was paranoid relative to making my own putty via amending epoxy with fillers and determined that I would purchase a two-part product. Marine-Tex appeared to be a good alternative. When mixing the hardener and resin I thought I was in trouble, because the consistency is like marshmellow cream. I didn't think I would be able to smooth the putty once applied, but I had read that a latex gloved finger moistened with water could smooth the putty to make a concave bond between the sides and bottom of the boat. It worked with little sanding. and only minimal amine blush removal before sanding.
