The 5 Best boat putties (2023 reviews)

The putty is a must have accessory for your daily purpose. It is great as a means of repairing non-critical pvc drain pipe. It is formulated to adhere to wet, dry, and submerged, underwater surfaces that are clean. It cleans up reasonably easily and it is great to seal boat holes. It is epoxy rated for wet use, even underwater.

The water weld is a thick paste, so it stays put where you apply it. It is easy to cut off a chunk, knead it into a uniform consistency, and a decent work time. It's tacky so sticks to surfaces. This worked very well for fixing a leak between the toilet tank and bowl.

Why We Like This:

Hardens nice and hard but is quite sandable too
Has many uses and is very strong
Works great to seal boat holes
Soft and pliable to apply, hardens to concrete strength

It is a lightweight, microballoon-filled, fast-curing 2-part epoxy fairing putty engineered to provide excellent moisture resistance. It works well and has excellent consistency over a wide range of temperatures. It's clear and satisfying when you've sufficiently mixed the blue and yellow to a uniform green. It is sufficiently cured to be hand-sanded in 3 hours or machine sanded in 4 hours.

The epoxy (and the polyesters) heat up as they cure, and the heat also accelerates the cure. It will set hard in a day and you can sand it easily.
