[Closed] AAAARAHAHASDEGGASG B*S*A*D Powder coaters have ruined my bike.

I'm sorry to say I think you're to blame here. Most places charge extra for masking, and I would expect a non-bike focussed place to just coat it as you give it to them. If you want it masked do it yourself before you hand it over, or specify, very clearly, what you want masked as you hand it to them if you're getting them to blast the existing paint off first.

If they'd masked the wrong areas you'd be even more annoyed, as at least everywhere you want covering, is covered.

Any good bike shop will have a BB tap and BB, disc brake tabs & headtube reaming/facing tools necessary to clean this up. In fact that's probably a better option than ruining the frame with a bad masking job and not cleaning it up and getting part jammed in the bike.

one question did you ask them to mask it off???

they probably didn't realise.

Just take your time reaming the threads out and your steed will be back as good as new.

Keep the faith

Not quite sure what you were expecting did you not tell them?

Most bike shops will have this tool, will cost you to get it done unless your a regular face, costs quite a lot to buy the tool so they'll need to charge you to pay for itself! (unless you buy a new bb from them).

Mine was a nightmare when I got it back from the powdercoaters, bottom bracket, seat tube, head tube, bottle mounts all trashed! But least it looks good!

I think you can only blame yourself here. I've taken frames to regular powdercoaters before and masked it all off myself first

heh heh 😆 its your fault pal

you should of told them where to mask or done it yourself before it got coated

As above, you're fault, not theirs. If you get a frame powder coated it's up to you to mask the threads, etc. Looks like you're calling the wrong people the 'useless w*nker'.

LOL

hmm, when I handed it over I told the bloke what I needed masking and he described his rolled up paper technique. I was happy that this would prevent most of the overspray and left him to it. he did nothing. the fork lowers were full of powder luckily that all blasted out with the pressure washer. I guess I'll pay the LBS a visit with my tale of woe and a wad of cash.
your a bunch of judgemental gits aren't you.

Taken plenty to my local powder coaters (cj's in Grimsby) and although I always mention masking, they always stop me in my tracks and tell me they'll do it all, never had a bad job yet.
Also if the OP was getting it shotblasted too, as I do, masking beforehand isn't really an option.

Any self respecting spray shop will mask the frame, sounds like the people who did yours are proper bell ends, think you should go back and complain and ask what the are going to do to put it right.

I don't think it's fair to blame the OP, it's the coater's fault. But, this is exactly why you go to a good coater who knows bikes and pay, oh, £10 extra.

TBF any coater shouldn't be spraying threaded areas. When you said you needed it masked did he reply 'si, I speak English I learn it from a book' 😕

Alarm bells would have been ringing in my head at "rolled up paper"

I stuffed loads of newspaper in my BB (they removed it and did the same). Next time I'll fit old BB cups.

Where did you take it? Next time, go to Bournes in Birmingham. £25 shot & coat, and they have seen bikes before.

Andy in 2 Wheels will help you, or you could take it to Race Co where you will be ignored if you don't want to spend lots of money.

A few blobs of paint striper in the threads and rub it round.

Sorted.

Stop being a drama queen you big nobber. 🙄

Next time I'll fit old BB cups.

I did that but they removed the BB.

They also removed the headset I left in.

Shot was stuck to the BB threads, which in turn wrecked the LBS' tool.

Shot stuck inside the seat tube ruined a seat post and I had to buy a shim and narrower post.

ironically the place had bikes on show as examples of their work hence why I thought they new what they were doing...

Redditch shot blasters?

Genuinely interested as im considering getting my old inbred frame sprayed up.

Boz.

Bournes in Brum.

Paint striper in threads, head tube and seat tube when you get it back.

Spare cash in your pocket.

Job done.

Bournes in Brum

£20 for strip and coat

it was black ...

You gets what you pay for..........

£20 - nothing masked, cost another £30 getting bits chase/faced/reamed

£50 - everything masked and the coating is a much better quality.

spoon.

You got girls hand or something...

😉

I will use Bournes next time as I used a powdercoating company in Redditch (near Halfords?) and I was disappointed by the rolled up paper technique (I accepted the suggestion admittedly due to my own ignorance of the powdercoating process) which still required some time with a small screwdriver and some paint stripper. I've also noticed some paint coming away near the headtube - I'm not sure whose fault that it is but I'd try Bournes next time.

This is what you get for using a powder coaters rather than someone such as Argos or Mercian who build frames

Go on then OP, which shop did it? I don't think it would have been Redditch shot blasters as they applied a silver foil tape over the BB and headtube on my last frame which you just cut off.

*Waits for pics of Micks Tiger Bike.*

sorry mic, just got in from the pub. it was city powder coaters in digbeth. They are clearly more used to car wheels,fences and radiators. to be fair it was dirt cheap, (granted not £25) so I do have the cash spare to get the problems fixed. I was just a bit pissed off earlier cos the enduro sl has so many bloody nooks and crannies, I at least thought the BB would be masked. that I had to ream the powder coat out of. wish I'd asked on here first to be honest. but no.... I thought I knew better than the internet brain trust. ah well hopefully it will be sorted this week and I can hit clent/wichbury for a ride.

nothing you can't sort with a loads of nitromors, patience and wire brush (u can get a pack of varying sized wire brushes from the pound shop ..for a pound).

This place is good too they definitely do mask ALL areas and that was on an 06 Enduro where like the SL there are loads of nooks and crannies.

As it's an aluminum frame..............

Did they shot blast it before hand?

Does it feel significantly lighter despite the heavier powdercoat?

If you had a 1998 carbon frame you wanted jazzing up would you be more wary of shot blasting and powder coating, or would there be nothing to worry about?

Cheers

I dont think I would be contemplating powdercoating a carbon frame paulrockliffe, powder coating takes an oven baking to make it work, dont think blasting or the oven bit will be good for your frame...

just spray it.

Don't know whether this is mentioned above as I can't be arsed to read the thread, but get some nitromors on the areas you want cleaning. It wporked very well for me when the same happened.

[i]the fork lowers were full of powder luckily that all blasted out with the pressure washer.[/i]

Did you leave the forks on?

Even if rigid I'd have taken them off.

what a load of rubbish. One bad experience is just that. The place loads of us Bristollers use don't have a clue about bikes but you mask them yourself and it's fine. Cardboard tubes (bog or kitchen rolls) cut lengthways and then stuffed with cardboard to keep them in place in the bb, head and seat tubes. Never had any problem. Oh and I reckon their paint is better than Argos', all for about a third of the price.

Any GOOD powdercoater would ensure threads and interference points were masked, properly unless you specifically told them not to.

But its not the end of the world, you can fairly easily re-tap your threads and quit whining, just make a note never to go back to them for work.

As said before - the coaters really need to do the masking after the frame is blasted. A steel frame done at a descent blasters should also go through a phosphate dip process (but not everywhere does). Again - no point masking it before dipping.

I doubt they actually "shotblasted" it. There is a pretty big explosion risk when you combine fine aluminium powder (from the frame) and sparks from chilled iron shot.......

There's probably a side job for someone here; collecting frames, masking and taking them to a decent powdercoater.

Normal that is I'm afraid. You need to ask them the question before they start.

This is the reason I have an old and very melted inside octalink BB knocking around. Blokes I deal with are fick-as-**** but do a nice finish for the money.

A lot of people giving this guy a hard time! You can't mask before you dip and strip it and no decent spray centre will spray threads or other area's without masking or plugging.

A good thing to do is get them to put the spray instructions on a work sheet not on the frame as some do with masking tape. As they will simply get blasted off.
Phone a few bike shops see if they have a park tools facing and tapping kit for the BB there are quite a few tools that do it but the park one is the most accurate and removes the least amount of material.

How did you get the extra paint out and what kind of frame was it?

Kaesae in giving advice about respray shocker!

Can I ask what one would use to mask? I have always had the 'coaters do it.

I have noticed they use these sort of rubber cones in threaded areas. The reason for the question is I know the oven is pretty hot.

Also... presumably if you left bolts in the frame and/or a BB/seatpin/headset then you would have to score around the interface with the frame to prevent chunks of Powdercoat coming off?

Those rubber bungs are silicone based and don't melt untill they get very very hot, well above the temperature they'd burn at as the oven usualy isn't inert. I accidentaly left one on the hot plate at work, so the melting point is above 200degC at least.

Also once the powder has gone on, theres no need for masking, so you could remove them before baking the frame.

The tape they use is just a high temperature masking tape

turns out I was just a bit cranky after spending such a long time with the wet and dry. It was a bit irritating to say the least. At least the friendly folk of STW have put me in my place and I shall MTFU. Nitromors is on and the soft wire brush will be coming out tomorrow.

Will take it to the bike shop to have the bb faced and the thread run through anyway though I reckon.

The fork lowers went in as well as the stem and crown. they didn't even tape off the steerer (which was the only bit of bear metal visible). But its almost all sorted now though so I think I should apologise to anyone I offended with the original tirrade of powder coater abuse.
