The galvanization process covers the surface of the metal with an oil and zinc coating. The first step in painting galvanized metal is to remove this surface coating using an acidic wash of either 100% vinegar or a solution of water and muriatic acid. Once the zinc and oils have been removed, the acidic wash needs to be neutralized using either ammonia or a baking soda and water mixture. This neutralization wash is then rinsed and the metal allowed to dry. Only then can the galvanized metal be primed and painted. Further, there is no need to use two forms of primer before paint. Once the zinc and oil surface coating has been removed (and acid neutralized), galvanized metal should be painted using techniques similar to that of painting aluminum. However, under absolutely no circumstance should galvanized metal ever be primed or painted with an oil-based product (only water-based coatings should be used.)

Very professional job. I never knew about galvanised being tricky to paint, this will likely save me from a load of hassle in the future!

Next time it would be good to see the finished surface when it is dry. Also interesting to see how you set up to paint and avoid making a mess. Great clip thanks!

I was reading , from Sherwin Williams: Most hydrocarbon solvents, including mineral spirits, leave a thin layer of residue that leads to adhesion failure of the paint film. Instead, use a water-based cleaner/degreaser to clean a galvanized surface. Most acrylic coatings will adhere directly to cleaned galvanized metal.

Rust-oleum PaintPlus 2x ultra cover is great. Their rust converter (which you don't need with galvanized metal) is far more effective than the Advanced auto product. It also bonds plastic. Great even coating. Beginners can use it easily

The best cleaner for galvanized metal is simply tsp. You must use a 100% acrylic primer. Alkyd and galvanized metals don’t go together. It’s sticks great for a few years then saponification starts and it will repeal the coating. It will peel. That’s all you need to know.

The TDS for Bulls Eye 123 _Plus_ from Rust-oleum specifically says it is for NON-galvanized metals. Yes, it will adhere, but then eventually saponification will set in and the paint will peel away. Bulls Eye 123 (not the Plus version) is for galvanized metals, as listed in it's TDS. Further, the TDS recommends ammoniated cleaners prior to priming, not TSP (it specifically says not to use TSP based cleaners).

Eche it with white vinegar or clean it with white vinegar. Will allow paint to stick for an durable finish. Top coat with oil base paint. Cheap an easy solution. Try it on anything galvanized. Also a deglosser would work. Or liquid sandpaper if you have to use latex.

What time in between is the drying TIME ? He says let it dry. Could you say how long, please? Thanks! Nice job 😀

Thanks for the video! Well done! Very informative.

What type of primers and paint are you using. Brand names are sufficient if the everyone has access to those, but…..

Why do you apply zinser as the first coat rather than just primer x 2 before top coat? i was going to use hammerite x2 before top coat but now i am thinking zinser as its cheaper and thats one primer coat down.

please do a video on the different types of metal paints,, go with the top 3 thanks

Mr UHM, I didn't mean that, I meant the cardboard box! I was being sarky. But I did have a question: why use a primer when you have used the zinnser? It even says its a primer on the tin.

How to clean & spray a galvanized Wind Turbine???? Any info????

I like that hint to clean out the nozzle ... I never thought of that and it's so obvious. I've thrown away more cans of spray stuff ... argh! Good hint, thanks.

I made a front splash panel for a vintage truck I am restoring out of new galvanized steel. The truck will not be driven in severe weather but it is up front, parallel to the ground and between the grill and the front bumper. my plan is to ultimately paint it with Rustoleum High Performance Enamel. One of the best rattle can paints out there in my opinion. I did not see anything regarding sanding it first to prep it and make adhesion better. I thought maybe using a DA with say 100 grit first might be a good idea. Then the Zinsser, then the paint. Sound logical?

Hello, is there a paint stripper for galvanized steel? I have loads of Crittal windows that need to be stripped of the paint that has build up over 70 odd years. We have tried scrapping it of but this is very time consuming and we have a lot of windows. Thanks

Methylated spirits is methyl (denatured) alcohol?

I think my gutters are just steel. They are darker than that. Do they need primer? For the paint, which kind?

Would ONLY epoxy primer and underbody coat work? Cold galvanized surface. And what is that first primer you put there?

Always liking your video's chez - Thanks.

Can I follow these exact steps for painting galvanized tent elbow fittings? And the polls?

Great video - thanks! Do you not use Mordant solution?

Doesn't Zinsser say right on the directions "perfect for non galvanised metal"?

Good day! Just wanna ask if can I use this method for the door bumpers of the Hospital. The double action door is made of wood so we need to put some galvanised steel as bumpers for the protection of the door. Will the paint torn out easily? since the galvanised steel is prone to bumps from the Hospital stretchers passing through. Thanks in advance!

where can you get one of those work benches from? :-)

Is the surface primer and Painters Touch oil base?

Trying to do this on galvanised scaffold pole and I can’t t get the zinsser to stick very well

great vid man, i heard about galvanied steel painting, with surfacing the galvanised steel with aceton acid first then primmer coat, does it really work that way ?

okay thanx that's helpful I asked my tutor today all he said was you can spray everything hes a bit of a joker though so I cant always tell but thanx for setting me straight :D

Is Zinsser 123+ required -- I have Zinsser 123 (no "+")? What does the "123+" do that "123" doesn't do?

Hi - goes it work on zinc metal with same primer and spray paint used for galvanised?

Thank you!

How's the best way to paint stainless steel bunk beds

how are you going to get paint runs on a flat surface

I've got a few galvanized mesh wire panels I want to paint. How do I evenly apply the Zinusser primer to a grid mesh without it getting drippy and splotchy?

Cool Good work love the video

could you explain how to strip paint from galvanised steel please? thanks

Thanks for that

You are welcome keep up the good work I've subscribed you you are one legend ;)

do you have to use spray paint to paint steel I thought most paints were applied by brush unless theres a reason as to why ur spray painting it??

Once painted, can you bend galvanized sheet metal?

Will this method work for raw brass metal?

Galvanized metal should be etched following cleaning using white vinegar, then apply primer and top coat. ( Not a bad idea to use a tack cloth before applying any primer or top coat)

will painting the metal take away from the magnetic properties?

will this process work on cold gal. i.e. bare ungal metal sprayed with cold gal not hot dip as shown her???

thanks for the info

Can the 123+ be sprayed on with a sprayer?

You don’t even sand it!?

Will this work on SECC steel as well?

Ever heard of slow, even spraying? This is really not the way to spray paint. Thanks for the info though.

how will the galvanize react with the steel if it doesn't touch it

U need to use edge primer

what kind of spirits

Methylized Spirits? (MEK) Methyl Ethyl Ketone? Acetone?

I need an explanation why two primers are necessary.....other than Rust-oleum is putting money in this chap's pocket for saying so. The BIN primer doesn't suffice alone? I find this Very hard to believe. Very.

why couldn't we just use paint spray straight away?

I'm from Galveston. It's illegal to paint Galvanized steel here.

Is this guy speaking English?? 🤪

Meeeee

;)
