painting galv...... can it be done?

[gelf]

can you paint galv? or will it peel straight off.

thought id ask before i make a mess

[white90]

Graham

it general chips off rather than peels

I've painted the Galv wing bars and they only require a tad of paint after an event

[gelf]

no special primer then?

[Holyzeus]

theres a primer you can use, maybe just an etch primer or a certain type in particular, someone will know

[white90]

I got some galv primer but it was rubbish

I just paint on Halfords Matt Black enamel

[gelf]

thank you

[madmatt]

Hammerite special metals primer is good on Galv never had a problem with it peeling

[Old Spot]

There is a proper galv primer, it is called "T Wash" made by a company called Mordent I think.

Baileys paints in Stroud Glos stock it, I don't know if they do mail order.

Priming galv is loads easier if the galv has been left outside to dull off before painting.

Have just found this website by the galvanizing industry body

You can buy T-wash Direct

I bought their IR103 (I think, there is a splodge on the label might be R103!) matt black modified vinyl paint sticks to anything including galvanised. Bought it to touch-up the nas galvanised bumper and rear step. Dries very quickly and good with a brush. Used it over an industrial red oxide primer last Xmas on a rebuilt glider trailer made from steel tube (Paul W made the new ladder chassis for me) worked a treat no problems so far. They have been making paint since 1899 so probably know what they are doing!

BTW as suggested above not suitable for new galv.

i was once told that urea is the best way to get paint to stick to new galv (ie pee !)

Why dont you call one of the many galvanising companies and ask them what they recommend

[tonyalbers]

I've had much luck with a mixture of linseed oil and black iron oxide together with some drying agent(siccativ). Apply in a very thin layer and let dry for a weeks time. You can paint over it with anything, and it doesn't peel.

A tip given to me (by Land Rover restorer Ken Wheelwright) was to always leave new galv steel out in the open to weather before applying any paint. Works for me without the need for any specialist prep coatings etc.

The proper way for painting GalvSteel is as follows:

Wash item using alkaline soap solution.

Rinse thoroughly

Dry

Apply suitable primer (acid etch)

Paint as required

Totally agree with above just use a decent wash / acid etch primer

or you could aways grind the galv off

I've done my winch bumper with etch primer and a couple of cans of spray paint and it stuck fine, just needs touching up occasionally to cover where it's been scraped off.

I used Hammerite Special Metals Primer on a brand new galv chassis, and it SUCKED.

It'd chip even if you just put a spanner down roughly on the chassis. Crazy.

Never again. Just seemed to have no adhesion and very brittle. The galv was totally clean.

I'd use acid etch if I did it again.

You have to wash new galv, even if you use etch primer.

As new galv forms a greasy skin that can lead to etch primer

letting go.

Or you just leave it outside in the elements for 6 months to

"sweat" it off.
