Marine-Tex Epoxy

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.

    I purchased a quart of white Marine Tex to repair one of my rudders on my son's Hobie 18. A portion the size of 2"X 2" broke off near one of the mounting screws.
    Rather than try to piece the two parts back together, I drove three deck screws at various location along the break and then tied wire to the screws to act as reinforcement. I created a mold out of cardboard in the shape of the corner and filled in with Marine Tex. The rudder is about 1" thick. The mixing went well and I used plactic spoons to mix the two parts. Finally used a plastic knife to place the mixture into the mold. The mixture took about half a day to cure but is rock hard. Will next shape the corner by cutting the excess and sanding the rest. Next will drill the new mounting hole. Next project: Repair cracks in the hull of my Sunfish. GREAT PRODUCT!!!!

    I read and followed instructions and found that filling vertical cracks (up to 1" thick)the product dripped or ran terribly and it was a battle to get it up to stay put until it started hardening in 45 minutes. Mixing proportions are not clear-cut with the kit supplied--i.e. weights and volumes of epoxy and hardener were not clear and whether all of hardener in kit could be mixed with larger epoxy container.

    Comments about Marine-Tex Epoxy:

    THE KIT COMES WITH A RESIN AND A HARDENER...MIXED AT A 95% RESIN TO 5% HARDENER RATIO.THOROUGH MIXING IS IMPORTANT.YOU HAVE A LONG "OPEN TIME" TO WORK THE PRODUCT, PLUS AMPLE TIME TO SHAVE, SHAPE , MOLD AND CONTOUR THE PRODUCT AS IT SLOWLY HARDENS.DUE TO THIS, YOU CAN PRODUCE A REPAIR THAT IS ALMOST PERFECT AND MAY REQUIRE VERY LITTLE SHAPING OR SANDING. I HAVE REPAIRED A 175 P.S.I. AIR COPRESSOR AUTO WATER DRAIN FITTING WITH IT AND IT WORKED GREAT! JEFF GEYER BOATWORX

            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.

But save the hardner. the job was sucessful. Glad I found M-T on web, may need a new supply in the next 35yrs. WHAT A GREAT PRODUCT!!!!!!!

                      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 !
