PC-Products PC-11 Epoxy Adhesive Paste, Two-Part Marine Grade, 4lb in Two Cans, Off White 640111

Easy to use and quite easy to smooth etc. sets solid pretty quick too.

Great tool, works great 😊

Still got the original leak, not as waterproof as claimed

I used this when I fitted a new echo sounder, through hull, transducer to my boat, a 10 tonne motor cruiser. The old transducer used two holes, one of 50mm diameter, and one of 10mm diameter for an anti-rotation bolt, but the new transducer only needed one hole of 60mm diameter, leaving me with an unwanted hole below the waterline. After drilling, fairing, and cleaning the 10mm hole to make good contact surfaces, I taped the outer hull and used PC-11 to fill the hole from inside the boat. The PC-11 was easy to dispense and mix in the correct ratio from the syringe, and it was wet enough to flow smoothly into the hole without any air bubbles. (An old credit card proved to be perfect for mixing and smoothing) The boat is now refloated, with this PC-11 repair submerged to a depth of 1.0m, and it's tight as a drum. All in all, the repair, including the mechanical preparation, took about the same time as it took me to write this review.

This product is fantastic, but I can’t stress enough ignore the instructions on setting time and always do several tests on a scrap of wood before your intended. Use disposable gloves, mix the hell out of it and then rolls and fold in your palm till you feel the heat of the chemical reaction. Mine took over 24 hrs to fully cure and not fail the mail test, but once it went off it was fantastic. Great product but test test test first.

My need for this is extremely unusual and unfortunately most people won't relate to it, but here it is anyway. I own a powerboat made of white ABS plastic and a small 3 stranded area of stress crack damage appeared on the decking near the transom. Due to the design of the boat this was purely cosmetic on the upper deck structure which did not carry the weight of the 60hp outboard. So I drilled out the tip of each of the three stress cracks and filled the holes with this filler, rated to be good with ABS. Job done, and after a recent 32 knot blast across the sea, all looks good and problem solved.

Used this pack to fill a crack in a retaining wall that was moving. Wall has not moved in more than year! Ideal where a larger amount of strong adhesive is needed. Bear in mind surface prep as otherwise will fail at the interface.

This is the best adhesive I've come across. Great for waterproof repairs on anything Ive tried it on
