Baking Hammerite

[rousejeremy]

Do you recommend baking hammerite finishes?

I'm gonna do it unless someone stops me!

I've baked smooth hammerite (on some bicycle parts). I'd advise doing it when your significant other is away, because it stinks to high heaven!

Baked or unbaked it never seemed too keen on sticking to aluminium. Never tried the original hammered stuff though.

I sprayed a test piece and stck in the toaster over. i'll se how it turns out. This one I sprayed once with a thick coat. Next I'll try two thinner coats.

I think you might get a "crackle" finish from what I remember reading on RG Keen's site, if my memory serves me right. Good luck!!

I bake my hammerite paints all the time.  I think it gives it a nice glossy finish and it drys very quickly.

Well, the thick coated ones turned out like this.

It could be the paint I'm using, it's Tremclad Hammered.
I have a can of grey Krylon Outdoor Spaces Hammered that has turned out much nicer in the past. It was summer when I painted this though.

The trick with painting hammerite is to use less coats, not more than two IMHO, and spray about 5" away with an even stroke, as if you were painting with a brush.  Don't spray directly, but spray away then spray towards the enclosure with an even stroke, this will prevent unevenness and paint from running.
