Ceramic Transom Pour Putty

True Composites Ceramic Transom Pour Putty is intended to use as a core material in the transoms of power boats.

Includes between 1 to 5 Gallons of Ceramic Transom Pour Putty with MEK Hardener. Its intended use is as a core material in the transoms of power boats. True Composites Ceramic Transom Pour Putty has a compressive strength of over 2,900 psi & is relatively lightweight (7.2 lbs/gal).

Boat manufacturing processes have improved a lot over the years, & True Composites has been there every step of the way. Our Ceramic Transom Pour Putty is becoming the standard for boat hull transoms, where extremely high compressive & flexural strengths & low exotherm in large masses are not only required, they’re everything. Today’s transoms hold more weight & power than ever before, & failure is not an option.

Repair: Rescuing Old Transoms

Many older powerboats were built with plywood transoms, which eventually rot. Our Ceramic Transom Pour Putty allows repair of these transoms that’s minimally invasive, takes less time, & is ultimately more cost effective.

But our customers have discovered many other uses for this versatile product:

✔Coring small parts
✔Providing a bed for mounting engines
✔Backing up two part molds
✔Repairing dry rot in transoms & stringers
✔Backing up marine hardware
✔Cyclone & separator bodies

Transom repair

I am very very happy with the results of this product. My transom is as hard as a rock now, and supports the 115 merc easily. I highly recommend this to anyone that has a transom weakened by wood rot. Remove as much rot as possible. I used the 1 gallon pails. Mixes easily and pours easily. Outstanding results.

Wasn't happy initially due to the missing bottle of MEK that set my project back a few days. Fortunately the company promptly sent me another. And after using for my transom rebuild, I have to say I am VERY satisfied with the product. Transom came out AWESOME!

Shipped quickly

Works great used it to make a water dam while drilling a hole in marble countertop - can't complain - rather large amount negates the need to by more in the near future.
