Painting water tank

The water tank on Havana is integral; it's under the front deck and is created by two bulkheads welded fore and aft of it.

We're going to paint the front deck this weekend and while I'm at it I want to lift the inspection hatch.

I daresay there'll be some rust in there as it's not lined.

But what sort of paint job can be done to it? Is there a specific paint for drinking water tanks that's non toxic?

Thanks

Back page of the Acorn catalouge.

I think it is one of Mainline's productes, but I bet Blakes do one as
well. I would expect any decent chandlers to stock it, but it might be
worth talking to builders merchants about how to treat asbestos or
steel water tanks - might save afew bob.

I saw my friends after they painted theirs - it looked as if they had
blacked their hull with bare hands and arms.


ps How's the sterngland progress?

Use good quality Bitumastic paint (the same as you slap on the hull below water line) Its non toxic and is probably the only substance actually recommended to potable water tanks.
 
Process is to open access hatch remove water if you have access to a pressure washer it will save lots of time! Also a wet vacuum like a Vax. You will find silt and some tubercular corrosion. Water blast or scrape clean. Remove all loose paint thoroughly clean out and dry. Also when you have the chance clean out the outlet pipe as it may be starting to clog up.
Apply at least 2 generous coats of Bitumen and allow to thoroughly dry (at least 24 hrs before refilling). Don't forget to also clean and bitumen the underneath of the hatch.
Seal hatch with RTV Silicone sealant. Or Acrylic sealant if you want to over paint the joint.
Fill up and run the first tap for 5 min. to flush out any bits. Then change the filter. If no filter this is the time to fit one !
There will be some drops of Bitumen dust in the water until they settle out or get flushed. They wont harm you but don't look nice. After a week the water should be clear. An inline water filter (not a purifier) will remove all the bits.

There are 'approved' paints, Bitumastic (Wailes Dove) and
International both do them. I think some hull paints are approved for
water tanks.
Note that Bitumastic is a trade name, they make a variety of paints,
including coal tar hull paints, which are not suitable for water
tanks.

Make sure you have plenty of fresh air when you're doing the painting.
The ideal is an air-fed respirator.
Make sure there's someone else keeping an eye on you when you're doing
it.
Allow *lots* of drying time between coats, otherwise solvent may be
trapped in the lower coats, and be gradually released into the water
after you start using it. Likewise lots of drying time after the final
coat, then fill empty the tank with water two or three times before
putting it into service.

We made the mistake of using some left over hull black to repaint our tank. it
reacted with the existing paint and tainted the water. The only solution was to
use a water based paint stripper and clean the tank to bare metal before using
a propriaty? paint possibly blakes potable water tank paint. Think about
replacing the bolts with stainless steel to fix the lid.

I have just finished painting the corrugated roof of the shed belonging to
our Village Hall. I was using ordinary bituminous black (v. good, v. cheap)
it said on the tin that is was suitable for drinking water tanks (The brand
was Ruberoid)
