Hi folks – welcome to my ferro-cement boat blog. I started this project about 5 years ago as a way of keeping a record of the process and also because there seemed to be a lack of information on restoring ferro boats on the internet. Once i had basically got it afloat and completed it to a certain level of usability I ran out of enthusiasm and energy, which are maybe the same thing, and sold it. A number of other things happened in my life and the lack of money and time made it the obvious choice. The lesson i learned from this is don’t walk into a big project like this with your eyes closed. Inevitably, as in my case, costs and work spiral; i discovered many more things wrong with it after my initial survey. Make sure you get good advice and do the survey properly.
There is lots of info on how to do ferro repairs and also a lot of chat and my take on how to approach working on a big project like this. In fact i ended up totally gutting the interior and renewing just about everything in the process, so it is a general introduction to all aspects of doing up a boat without the finer details of how to do the work, I am assuming that if you’ve got this far you are a skilled person. When i first started it i used a site which gradually deactivated certain features in order to get money out of me so i had to switch to wordpress. This means that the first few months of blog are contained in added pages and can be viewed towards the end of this main page. My efforts in this direction have stopped short of putting everything in an accessible format so you’ll have to persevere if you want to find everything.
From the hits on the dashboard i have noticed that there continues to be interest in the site which comes from search engines so i am assuming that this stems from the tagline or title as being about ferro- cement boats. on that count here is a quick summary of my experience in repairing the hull.
There are a number of general cement repair epoxy mixtures as well as specific marine epoxies, all of which vary in grade and price. To some extent you can choose the fineness of the filler ingredient to suit the application. But as with the original cement mix there is an optimum balance of grades or fineness of aggregate which gives the strength and fluidity of the mix. According to the manufacturers and experts, the strength of an average repair epoxy is at least as strong as the best original cement. The crucial aspect is in the adherence of the epoxy to the cement which is why epoxy is used below the waterline because there is less strength in a cement repair when new wet cement is applied to old set cement which may also contain impurities sustained in the damage. This is partly because the setting process of cement is a chemical one and not a mechanical one, whereas epoxy is mostly the other way round, especially in terms of sticking to a foreign material.
Anyway there is more contained in the blog which should be findable from the photos. As I said the boat now belongs to someone else so for me it is a fait accomplis; my life has moved on and pastures new etc. Happy boating!
