Hammerite direct to rust

[ajs123]

Hi, my galvanised gates needed freshening up so I put this stuff on. Looks ok on the bars, but on the bottom panels you can see every brush stroke, looks worse than before. Gave it a light stir as directed, but the top of the paint maintained a sparkly look, just doesn't look right, is this the finish to be expected?

If you painted direct to rust, I guess so

You can probably improve the look by waiting a reasonable time for the paint to dry and then a light sand. It takes a while to go off, and if too soft will mess the job up

Being xylene based, Hammerite is a most difficult product to apply on any larger area.....the brush picks up the paint every time and causes streaking. This is called ‘overbrushing’ on the can.
Although it has its uses on metalwork, it certainly doesn’t cure rust. Maybe you’d get a better finish from a spray can?

Cheers guys, there was no rust it was just weathered, assumed it would be ok and all that screwfix had in, would the "normal" satin paint sit ok on top of this? Not happy tho

Can you give us a picture or two?

Worse than before despite following instructions

Would normal gloss go on this to make it better? So disappointed with this product as not cheap. Thank you

Is that wood?

 

[ajs123]

Nope, metal. That's why I can't understand the state of it, if it was cheap paid I'd understand but this is probably one of the most expensive. Not impressed

 

[Burnerman]

For sure, its a difficult one. You could improve things, I think, by laying the gates flat and going over them with a Hammerite Smoothrite silver aerosol.
No guarantees of course, Hammerite is awful to remove and will only sand once its been on a while.

Cheers mate, can't believe the state of them. I might get a generic metal paint and roller it on, see if that helps, should have bought the cheap stuff in the beginning

 

[Burnerman]

I dont know if its any help, but instead of Hammerite I use Johnstones smooth metal paint - its claimed to be a ‘specialist coating’ ( yeah, right) but its a darned sight easier to apply.
At least you can brush the stuff!

can't clean the brushes after using it either.

You say that the gates were galvanised. Presumably you used the "direct to galvanised" version?
