In the process of learning how to and preparing my ship after I first purchased her, I came across a cement care/protection product at a Habitat For Humanity thrift store. The product is called DP36, and it's made by ProSeal. The product is apparently used to protect swimming pools and other cement from...chlorine and saltwater. They used it on the Panama Canal.
I bought 44 gallons at $4USD a piece, figuring that since it was $400 gallon from the manufacturer or retailers, that I was getting a good deal no matter what.
I tested it on my deck both above and below (I'm laminated ferro-cement). Above deck, it has stripped the paint off. Below deck, it excluded the black mold which infested my ship (and which I have a genetic condition that puts me in the class of most sensitive people to it.)
Some of it dripped off the deck and onto the hull, where it also stripped off the paint.
Given that DP36 works by creating a polymer matrix of polycarbonate, it actually displaces everything in the cement, including soil, grease, and paint. It creates a vapor-tight barrier, which I figure makes it a damn valuable product.
Has anyone else heard of or experimented with this product or similar?
Curiously, ProSeal also has new products, though they have not responded to my inquiries to test them on my ship, specifically their rubberizing coating for cement as part of a system which creates an integrated layer of rubber in the cement itself. As mentioned in my initial post, I'm very anxious to work with this company or any other (or just try it myself) to integrate silicone into the cement matrix on my hull, creating the ultimate in anti-foul coating that would also be tremendously low in the friction department.
Perhaps one of you more professional and "normal" blokes could contact ProSeal and try to get them to give up a batch of their rubberizing system to allow it to be tested as a bottom coating.
Otherwise, I expect to be able to start experimenting in a couple years, once I find a home to do the work my ship needs.
Anyone else find any cement products that they have defied manufacturer expectations and used it on your ferro hull?
