Product Details

TotalBoat Polyester Structural Repair Putty makes critical bonding applications on polyester laminates easy, strong, and permanent. Its trowelable, thixotropic formula spreads smoothly & won't sag, making it great for fairing vertical surfaces. Polyester Structural Repair Putty is also easy to shape, so it's ideal for radius forming.

Reinforced with long strand milled glass fibers, this high-strength, fast-setting marine bonding putty adds strength & dimensional stability to structural, boat building & repair applications including bedding and tooling. Great for reinforced bonding on hulls, decks & stringers, and multi-purpose bonding on FRP composites, core materials, and wood. Add 1-2% MEKP catalyst based on mass, ambient conditions, and desired working time.

Available in Quart and Gallon Kits that include MEKP catalyst, and 1 spreader.

Tech Specs

Shelf Life/Stability Approximately 3-4 months (can be longer, depending on storage conditions). Keep container closed tightly, and store in a cool (below 75°F), well-ventilated place.
Info & Guides

Great for Structural Bonding, Filling, & Fairing Above or Below the Waterline

TotalBoat Polyester Structural Repair Putty uses a premium resin reinforced with long strand milled glass fibers for strength and impact resistance. In addition to structural bonding, bedding, and tooling applications, it's perfect for filling larger voids and gouges that are too deep for cosmetic fairing compound.

This high-strength polyester putty is engineered for structural bonding, filling, & fairing, not for cosmetic filling and fairing. For cosmetic fairing and repairs requiring a fine finish, use TotalBoat Polyester Fairing Compound over cured Polyester Structural Repair Putty. Allow the Polyester Fairing Compound to cure, then sand to achieve an extremely smooth surface ready for gelcoat or paint.

IMPORTANT!

TotalBoat Polyester Structural Repair Putty will not cure in air, and requires overcoating with an air dry material such as PVA (polyvinyl alcohol), paraffin wax, polyester resin with wax, gelcoat with wax, or TotalBoat Polyester Fairing Compound, in order to effect a proper cure.

Shelf Life

Polyester resins have a limited shelf life and will, over time, harden in the container without the addition of catalyst. Shelf life is dependent on a number of factors such as product formulation and storage conditions. As a general rule, the shelf life for uncatalyzed polyester resins should be up to 6 months when stored in dry, cool conditions below 70°F. Warm to above 60°F before use.

Hard as a rock

3 years ago
I am impressed with the hardness of this stuff, but it's a little brittle. There is definitely a use for it, but not where flexibility is needed. I used it to repair some small holes in the keel of my wooden boat where a few screws rusted out,and left small voids-which caused leaks and some rot. I am very happy with the sheer hardness and strength. I am a little concerned about flexibility. If your application requires flexibility, keep looking... the right product is surely out there. If you don't need any flexibility, this stuff is amazing!

Product works extremely well for a casual diy. I am undergoing a stringer and transom replacement. This product takes a lot of guess work and time out of mixing a thickened product. The consistency is prefect for fillets, bedding stringers, filling small holes etc.

Cored out foam from a large/long wheelhouse window along the starboard side opening and needed to reinforce and seal it. Worked perfectly and I was able to completely fill the cored cavities overhead as well as the curved and flat surfaces without any issues. I mixed small batches of 6 oz at a time to insure proper mixing. Note: counting drops can be an issue so a standard medicine dropper conversion is...20 drops= 1 ml

Stuff works, not sure I got the right catalyst...

5 years ago
Product is easy to use once it's mixed with the catalyst. Not sure if it was a mistake or the norm but I received a small bottle of liquid MEKP catalyst, like you get with liquid products like resins, to use with this product, which is a paste. Not impossible to mix but dang hard to measure out a small amount of each. Would rather use a paste catalyst like you get with other fairing products.

This is certainly a TOP quality product.

This product is easy to mix and use. Mixing and application is a breeze and sets up to be rock solid (literally speaking). It appears to possess superior adhesion properties. It's work time (pot life) when mixed according to instruction is right about 15-20 minutes which affords adequate time to apply it as needed. My application was to repair the transition between the transom and the hull as well as to repair the transom itself on my restoration project on my Combo Cruiser. I am very happy. The ultimate test is longevity and so the clock is started. Initial impression suggest that this product will prove to be a great buy.

Q: What does 1 oz of the polyester structural putty look like? I'm guessing a golfball? Thanks Joel

a year ago
1 Answer

A: Hey Joel. It's pretty close to a golf ball in size, but it's much more precise to measure by weight if you can. You should shoot for 1-2% catalyst by weight. So for 100 grams of putty, you'd want 1-2 grams of MEKP depending on the temperature.

Q: I am replacing deck in boat. Was wondering if this product can be used to fill the area between the deck and the hull?. After I use this product I would like to lay 1708 Biaxel with epoxy resin, are the two products compatible?

a year ago
1 Answer

A: They are not compatible. The Structural repair putty would first have to be cured by overcoating with PVA or finishing resin, allowed to cure then sanded. You would be better off mixing some TotalBoat Milled Fibers into your epoxy. That will thicken it to the same consistency as the structural repair putty.

Q: I want to use this for a different application. I have a fiberglass Santa Claus sculpture (life size) that needs repair. Do I just use this product or do I need fiberglass tape as well? The repairs would be inside and outside the scupture so I also need to paint over it - will it take painting? Thanks in advance for your help. Chris

2 years ago
1 Answer

A: Santa is larger than life... Hard to advise on your repair without seeing it, but if the damaged area is flexible at all, use the putty to fill the gaps, fiberglass over for strength, then overcoat with fairing compound to get the desired shape. You can send pictures to info@totalboat.com and a tech may be able to give you more info.
