Home powder coat effect
givemethebighammer - 13/8/04 at 08:36 AM

I found this idea on the Westfield forum.

I know that there are mixed view on Hammerite, but I have sucess in using it in most applications.

First paint the part (brake caliper , whatever) with one brush on coat of Hammerite, smooth it off as much as possible with the brush. Then with the first coat still wet, spray a single light coat of Hammerite (of the same colour and type) over the top of the brushed coat.

Result nice smooth finish.

Now let it dry for a good week before you do anything with it.

I've used this to good effect to touch up my black powder coat. I found hammerite satin black to be a very good match.

Cheers

We just got smooth hammerite and put in the gun with some acetone (nail polish remover) from lidls and that gave a great finnish. POR15 is the best but for touchup hammerites cool.

It has been on the mountian bike for over a year and still looks great.

The whole thing boils down to preperation and degreasing degreasing degreasing degreasing say it again degreasing.

Ive found that cellulose thinners thins down hammerite (both types)no problem and is sheds loads cheaper than hammerite thinners if you buy it by the gallon from a paint supplier.

Hammerite (hammer finish) has silicone in it (and the thinners) , to make those nice little rings in it. which is why you shouldnt mix the brushes with normal paint / brushes.

You can use ordinary thinners, but you may not get the hammer effect to well (diluted?).

Personally speaking I dont like smoothrite, as its very hard and chips a lot. ie not much good on a Land Rover!. The original Hammerfinish is much better.

I use farm chassis black from my local agricultural merchant. Its good stuff, and Pig/Cow P*ss resistant as well. Cheap, cheerful and it works. I am not sure how good its going to be on the Locost!

Celly thinners are too agressive for hammerite (metallic synthetic with silicone added to give the hammered effect), it will break down the paint chemically and make it less resistant to wear, sunlight etc
