Reasonable Price For A Powdercoat


Nannerman

Recommended Posts

spray paint is the way to go, a decent spray job requires paint stripper, primer, your colour of choice and a lacquer, i got all of this for about £35, it's not better at resisting damage from knocks and scrapes, and if you get a bike powder coated the heating process can f**k up your frame (allegedly) usually costs £50 upwards, it depends if they prepare you frame before they coat it though...

This sounds like a good plan. Is there any way to get the paint to stick to anodized finish? How do you think I would get that off? I've had bad luck with spray paint in the past, but I don't think I primered, or did the clear finish.

Thanks!

Powder coating can come off in trials especially with impact damage which you get in trials a lot. Bad move really. Your best of either sand blasting or as ogre says spraying.

Plus how many trials frames come from factory powder coated now? Not really many i suppose?

Im going to make the assumption that powder coating a frame would be more expensive than spraying?

If so it would only make sense for companies to spray their frames, instead of increasing the final price by using a more expensive finishing method.

"Can" being the key word. Like I said, if done properly and well, it can be a tough finish.

My Ice wasnt powdercoated, and that thing chipped its finish so easily.

Impact damage. Im gonna say no more. Same as when you curb your alloy wheels on a car.

Yes it may hold a great finish but durability wise i would not rate it.

Besides you cant expect every paint job/finish in the world to be virtually bomb proof. it will soon scuff/scratch/chip etcc... Whether its a bike frame, cars

The same damage will be done if it's sprayed. You scrape any finish and marks are going to show.

Powder coating gives a better finish, and if done properly, will be tougher. You may have not rated the durability of your GU, but every finish is different from different powercoaters.

I've a mate who had his frame powdercoated in Hull a while back, and he was a beginner, so lots of hard knocks and scrapes, and it held up incredibly well.

a one off job is cheaper to spray, but if your preparing frames in bulk powdercoating makes alot more sense

it's cheaper to powdercoat in bulk, one offs make more sense for spray paint... (as far as i'm concerned at least)

take some sandpaper to key the anodised finsih...

the big thing with spraying is to be patient...

lots of thin coats, with a good space of time between each layer.

i emptied a whole tin of primer on my frame before i started applying the colour

then i got excited and over did the colour coats and it beaded a tiny bit...

but yeah, take your time, be sure to cover the threaded sections and headtube...

i found that ducktape in a tube so the sticky was on the outside was a great way to go for my BB and headtube.

also stick a broom/pipe/long tube/etc

through your BB and mount the tube on something and you can spin your frame around it on an axis, using the headtube to control the bike...

Doesn't powercoating require baking under a shit ton of heat to cure? Wouldn't that mess with the heat treatment process involved with ally frames? Probably why you don't see many trials bike frames being powdercoated?

That is a complete theory / guess.
