Permaflex is a hard glossy rubber surface that when wet feels like an extremely slick oiled surface. It also is pretty strong when layered on thick.
It would be very nice to find out it works, since if it works, it is a permanent solution, never needing to be recoated.

They had uncoated controls that they say grew 2 inch thick encrustations.

I will definitely keep this updated over the next year.
Boat is in Hampton VA in the Chesapeake bay near Langley AFB.

The boat is totally dry, no sea water comes in and the hull is totally sealed on the inside as well as outside. It was a total rebuild with many new frames, screws and each frame and plank piece I individually coated before assembly with permaflex.
Here is what it looked like with 2 coats

Re: Sani-Tred Bottom Job ?

I used sani-tread to do my decks and can attest to itís great adhesion and elasticity

The primer will anchor to any roughed up surface and then the 2nd partÖ Liquid Rubber Base (LRB) bonds incredibly with the primer.

I think it would work well as bottom protection and can definitely fill in any voids or damages on an older hull (any material) as you can add a thickening gel so as to putty it on.

Not sure if it has antifouling properties by itself and the danger if you apply it, then need to apply an antifoul paint on top of itÖ you would need to find a flexible antifoul paint that matches the elasticity of Sani-Tread.

Here are some photos of us applying the rubber non skid chips over the wet primer, before we poured on the LRB then painted with a topcoat. (which is same as primer except with U/V properties

I was disappointed with the Sanitread Topcoat as I found it got moldy and stained during the rainy season. The manufacturer said we could coat it with any paint which is where I found the epoxy on top was not flexible enough and started to craze.

We finally went with an elastomeric roofing paint that is working very well and looks great.

The biggest problem if you used sani-tread on your bottom, would be trying to get it off, if you didnít like it

It only comes off with the company's special stripper.

Re: Sani-Tred Bottom Job

Hey Pelagic, what roofing paint did you use? How does it look now? I too have the Sanitread down, and am about to overcoat with a new layer of sanitread on the decks, but am tired of having to repaint everytime i want a clean deck. They told me to clean it with Zylene, but all that appears to do is smear the dirt around, and make the entire white deck, grey...
