water tank

[haza]

hi every one i hope all is well .well i think its time i redone my fresh water tank .i was wondering if there was any new products out there on the market since i last done it .thanks in advance regards

Is this an integral steel tank? Are you referring to painting it?

[blackrose]

Assuming it is an integral tank, what was it previously "done" with?

[haza]

black bitumen but forgot the name of it sorry

The best stuff for a steel water tank is two pack epoxy, BUT it costs a lot more than bitumen AND it has to be applied to a clean, suitable surface, and bitumen is not a suitable base coat, nor is it easy to remove every trace.

When this came up a while ago I said that bitumen paint is no longer approved for drinking water tanks. Someone replied with a link to a manufacturer's website or data sheet saying their product was not certified for use in new tanks, but was ideal for recoating tanks previously painted with bitumen. I can't now remember which manufacturer/product that was, but a forum search might find it.

Good stuff - used it last year (twice!! - take careful note of the ambient temperature parameters).

This explanation is also given if you look at the water tank bitumen product on the Midland Chandlers site.

We used it on the boat we bought last year. Tank had been very neglected and took several days to clean up properly. Rylards went on beautifully and has been very successful. Tank is still looking immaculate (emptied and dried it over the winter).
