Hello, J.

Glad you got sorted with your on-board loo.

Which one did you go for...and what thoughts on your experience since can you share with those of us considering an on-board composting toilet please?

Many thanks!
Mike

Tercoos will work 10 times faster than any other wire brush BUT (and this is a biggie) they only like flat surfaces. The comments here are quite right, they are expensive but will last as long as you keep they well away from corners, rivets, edges, etc. Once they hit anything raised, they lose their effectiveness quite quickly. User a cheaper wire brush for those. I just had a guy helping me do some work and he sent a Tercoo into the drink - aargh!

Anti-roestvet is great - I bought the cheapest hot plate and cooking pan from argos and used a long handled brush from screwfix. It was good fun, I swore when I stood on sticky wax but no more hassle than mixing two pack. I also didn't feel like I'd been working in a nuclear reactor by the end of the day.

I'm at Limehouse and have a 28m barge with some parts treated with two pack, some with Anti-roestvet so if you'd like to compare, get in touch. They are both equally effective and fun/difficult in their own ways. Having used grinders, shot blast, wire brushes and apache helicopters to clean my bilge, I'd say that the Tercoo is by far the best but you have to be careful with corners/edges.

Good luck,

Paul

Just found the answer, "hull grease" aka. 'Anti-roestvet' hull grease.

Hello Adrian,
Thank ypu for your article on how to treat bilges the Dutch way with grease. What type of grease would you use? Would stern grease be suitable?

Hi Joan,

To answer the question about preparation.

Agree that after a few months rusting, the millscale will have rusted off.
So grinder wire brush or something else. There was a recently forum discussion on the merits of wire brush vs the Tercoo disks used in a standard drill. Grinder wire brush can polish the rust rather than remove it.

I've just been in a yard where 3 20m+ hulls were stripped with Tercoo disks - the 2 and 3 disk versions.  Slow work but a really good surface for painting, and a couple of days to strip a hull. The disks are not cheap but very effective.   No slower than by wire brush.

If you will have lots of flat areas in the future - decks and superstructure, then it might be worth looking at the Fein Tercoo machine with 8 disks which are individually replaceable. Not cheap at around £400 though!

Hi Joan,

> I am a bit confused by the statement about primer...

"Shot blast and primed" steel comes primed with a pinky red weld primer to protect the steel during construction. If construction has been clean and the steel hasn't been trampled about on with muddy boots etc!, it should just require repriming along the welds and a spirit wipe over. Then the paint system is applied.

SB&P is a little more expensive than plain plate steel but cost is more than offset by less preparation for painting, if the paint job is to be thorough. The shot blasting also de-stresses the steel, probably not too important in your application, but any curves will be smoother.

In my limited experience from early 2000s visiting UK boat builders, they rarely considered SB&P as it cost more. The exceptions were the kit cutters. The Dutch boat builders and yards I visited wouldn't dream of not using it!

Hi Colin
The hull has been totally overplated and it has been on for about 5months .it has rusted over now so I'm assuming that all of the mill scale has rusted off by now
I will take photos and post on here at the weekend
I have been told by the guys at the boatyard and Richard Stickney (my welder who's brilliant) that all that needs to be done to prepare the hull for painting is it needs cleaning with a wire brush on an angle grinder. They don't sandblast at the marina
I know how important it is to get steel as clean as possible before painting. I am a bit confused by the statement about primer I thought the steel had to be free of any preparation including primer .can someone clarify
Thanks
J

Hi Joan
I have been looking into hull treatments and quite like the look of Keelblack. www.keelblack.com . I have also looked at Fertan as a pre-treatment. Alan Thomas from Fertan would be a good person to have a word with. www.fertan.co.uk

Joan,

>applied to new steel which has rusted over so what kind of preparation is required before the paint is applied.

Was "shot blast and primed" steel used - pinky/red primer on the steel? If not, likely to be steel plate with millscale still attached which really needs removing. Ideally by some form of blasting and then priming.   Especially important if steel being coated with 2 pack paints.
Plus possibly a spirit wipe over to remove any contamination.
What is the boatyard suggested paint scheme?

If millscale is not removed, it will cause problems in time.

2 pack epoxy is just a generic description for 2 component paints.  Long life on properly prepared steel. Most paint specs will have the phrase "surface prepared to SA2½", which is a degree of surface cleanliness and roughness.

2 pack coal tar epoxy is I think a name used to infer in water durability and use as the old coal tar paints on boat hulls, rather than any inclusion of actual coal tar.

I use a dutch 2 component paint, Shipcoat NL Epoxy Tar Replacement. Doesn't seem to be any coal tar in it. It is a toughened egg shell/ matt black paint designed for long immersion and can be used as a primer for other coatings. Good finish when put on by roller. Sure that UK paints offer something similar.

Hello
Well all the guidance I got for my toilet really helped a lot so thank you for that.
But now I have a mega query. I will be painting the hull next week and I was looking at two pack epoxy when I stumbled across two pack coal tar epoxy . what's the difference (if any) and if there is a difference what are the pros and cons of either of them.
Just to let you know I have had the entire hull over plated so it will be applied to new steel which has rusted over so what kind of preparation is required before the paint is applied

Thanks
J

Hi Joan,
We have had a Separett for ten years, with no complaints.
If buying one now, I would probably go for a Kildwick (Kildwick.com) or one form the Little House Company (littlehouse.co) - their designs are much nicer.
I don't think Simploo have the best reviews when compared to the others that are available.
There is a great Facebook group called Compost Toilets for Boats and Off-Grid Living. They have some very useful documents to help you decide what loo and whether to go composting or not - it doesn't all happen in the loo itself, so you need a storage system. It's not difficult or smelly at all, so don't be put off. You can ask any questions on the FB page, where there is a wealth of experience.
Good luck.
Lorna

Hi All

Whilst researching toilets I came across a company called Simploo . I was wondering if anyone has one of their toilets or if they know of anyone that has and if so what is their opinion of them

Thanks

Hi Joan,
I presume you have probably already spoken to the Centre for Alternative Technology? www.cat.org.uk

Thank you
How long have you had yours and are you pleased you decided to get a composting toilet? Also which model did you get and why ?

Thanks J

Have a look at Air Head & Natures Head compositing toilets.
Natures Head is an Air Head copy. We have the Air Head unit which works OK.
