Paint touch-up for steel cycle store

Postby Graham » 19 Sep 2017, 8:03am

It is a galvanised steel cycle store.

It has a small area of paint damage on the top. As the years go by the adjacent paint edges are beginning to lift.

I have sanded down to smooth the edges,

Primer? Humbrol? Hammerite?

I think I have answered this myself.

Hammerite "direct to galvanised metal" paint.

Hoping that it will form an effective bond with the adjacent feathered paint.

Pretty sure you can buy a "Galvanising" paint that might be a better cosmetic match than Hammerite.

Screwfix do a rattle can of the stuff. Ideal for patching I would think

I used to apply this stuff commercially, it does what it says on the tin. http://www.zinga-uk.com/

I bought this last week, but haven't tried it yet
Only 500ml, but weighs and impressive 1573g!
Salesman said he holds onto the can when he sells it in case the customer drops it :-)

I'm not sure a zinc-rich paint is the correct paint to adhere to galvanising. It used to be a horrible yellow/buff paint called calcium plumbate (can't get it now, I guess because of the lead). It may still be available for industry (I think they use it on pylons), the modern 'equivalent' is etch primer I think.
