Have you ever stripped the paint off a bike frame? If so, how did you get on? Let us know 👇
Yes, it was laborious to say the least. Spent literally weeks sanding and removing paint. It stung a bit when I realised I still had proper stripper on the garage shelf from when I had refurbed a set of car wheels. My tip is to find out the main ingredient in old school paint stripper and order direct from a chemical company. You might pay more in postage (hazardous chemical transport) than for the actual stripper but it will save you days and days of sanding!
Alloy wheel refurbishment companies use high strength paint stripper or sand blasting to remove all the paint. 👍
I've fairly recently done an oldschool BMX respray, without the right power tools, I know now that its best to;
1. while your still keen, work on the intricate parts like all the brazing, welds and lugs.
2. give the entire frame a sand to at least compromise the lacquer finish.
3. then, especially if it looks like too much work to sand, you can apply paint stripper.
But don't leave the stripper on for hours, I'm certain the directions advise against that. The blistered paint is removed best if you catch it while its still pliable.
P.S
Pitted chrome components come up nice after a dip in an oxalic acid solution.
Yes , and it took forever but the finish was very rewarding . The only problem is preventing the aluminium oxidation and now after 2 years it looks
like something from the Mad Max movie
I don’t know if it’s available in the UK, but I used ”Troton remover” multiple times with great succes. You just spray the surface and the paint basicaly fals off on it’s own. It’s quite cheap but sometimes you do need 2 cans.
I strip my paint using rocks from the trail
😂😂😂
And there is cable rub, or you lock your bike against something hard and square...
Rock garden, best tool ever, remove your rear wheel firat, that’s the way to remove any paint and mud from reat triangel
I strip my shins using my pedals
i like to fall of the bike while im trying to gap some stair sets to strip my paint off
Local car body shop, twenty quid for the bloke to stick it in the shot cabinet, ten minutes later, job jobbed!
Well that would be a lot easier
Was thinking the same thing. Would be good to see a part two doing it over with expert help.
My thoughts exactly.
All of the yes on that one
And then get it powder coated at the same time.
You need to roughen the paint up by lightly sanding with 80 - 180 grit sand paper before applying paint stripper so that it will soak in and lift
Henry should see this cuase that the right way
Yeah man! 100% this is how it's done.
He did
I actually realy thought this was great...the fact he was only armed with knowledge from viewers comments and a little research of youtube made this all more real world for people out of there comfort zone. So i only feel it is right that this should become a series....we have Blake builds so now we need HENRY HOPES!...glad you put the vid up Henry.
Henry has a mental breakdown part 1
@@stanp2281 well now he has no job or Covid payment, yes probably.
This is actually a great point. Do stuff people of the internet recommend. Now I can only see one problem with that though. With a little experience, you will know, not to do most of what people on the internet suggests. I hope.
Ha that's a very generous take on it. I prefer not to waste my time on a lets-see-what-happens video. Life's too short.
10 out of 10 for sticking with it Henry. 👍
"I was like a kid a Christmas, brimming with enthusiasm as I excitedly inspected it, before I realised Father Christmas hadn't left me any presents and Rudolph had left a turd in my stocking"
I was eating when he said that and almost choked myslef .
Went through the same process myself. Stripper never worked like “advertised”. Happy to see I’m not alone with my paint removal problems haha.
I need some stripper that was probably banned in 1964
I recommend watching a dude called, ETOE he's got mad bike designs & spray painting skills.
He's putting dozens of hours into this and gets paid accordingly in addition to being an amazing airbrush artist. If you try following his tips, you'd be better off sending a frame to him right away.
Martin has mentioned many times that a full paint job (simple of one obviously) would take a DIYer a good week or so.
This whole notion of wanting something to be done fast is really not very conducive to a job well-done on a DIY project.
Love the shiney aluminium. Reminds me of the all the GT bikes from years ago.
I would die to see Henry do a custom paint job 🤤
Scuffing the paint beforehand with rough sandpaper will make the stripper work much better. It also helps to lay it on thick.
Great job Henry, the results are worth it, this will give you a unique bike and a great conversation piece on the trails. I did this to a bike I have that you actually featured on top mods. I used furniture paint stripper and mothers mag wheel polish and found great results. Look forward to you doing a complete build on this
Henry this video was awesome! You get a lot of tutorials for various things and the video makes things looks so easy.... yet coming to do it yourself... something always goes wrong. Love to see how people get around problems, This is how tutorials/builds should be!
I sanded down an old dirt jump frame by hand and couldn't manage to sand around all the cable mounts and welds so finished it off with paint stripped worked like a dream. I ended up putting a few layers of clear coat over it but now it has started to have some surface rust come through. Its been turned into a ski bike now. Good to know the nukeproofs have good paint as I own two.
Pay someone to sandblast the frame
When it comes to stripping the paint back to the metal it is best to avoid sand paper or orbital sanders, there is actually specifically designed paint stripper discs that you can get for grinders / drills and dremal's, they are like loose fiber pads like scouring pads only harder, but they pull the paint off in seconds but do not damage the metal if it is steel, alloy frames will get some marks but no where near as bad as sand paper marks
Do u mean like the paint prep wheels from Screwfix ? Are they better than paint stripper?
Wasting lots of plastic here.
Edit: this seems like a sneaky way of demonstrating how high quality nukeproof paint is!
Or how useless modern paint stripper is!!...
Nukeproof paint
We just got bad paint strippers, i speak from experience restoring bikes for over 15 years, i got my self a sandblaster, got no time fuzzing around with water in a can trying to remove paint.
Well someone messed the original paint up at some point. But yeah, thick coats alright.
The only stiff in the UK that is strong as the law will sell is the power strip remover
Amazing video, so clear and concise.
bravo! patience paid off!!
I did this last year. Apparently in the states they don't sell the really gnarly stripper anymore that made the job look oh so easy in numerous youtube tutorials... still got er done! Albeit with some chemical burns to the ole mits.
"Safety glasses when using paint stripper" 😳 It flicks off the brush. Bike shops don't sell spare eyes 🤓 Good channel 👍
definitely need to see it built up
Perfect timing! I’ve done a pretty horrible job myself this weekend so with this video in hand, time to go back to the drawing board... thanks!
I recently did this and had the same issue with low fume stripper. I used Sellys next and that ripped right in. Still only did about 85% of the job so there was a lot of wire brushing and sanding the nooks and crannies but it's a great way to tart up an old bike.
Super polished raw frame....walks past his Pole....😁
What i did before instead of a spatula, i used a hose with a high presure tip to wash off the paint remover and the flaked paint. This reduced the scratching and even eased the removal of the paint. Just make sure you have rubber gloves and safety goggles.
OMG! I’m SO glad I found this video! I’ve watched untold restoration videos where they slap on Nitromors, the paint bubbles up, and then virtually wipes off. THIS VIDEO is what really happens! I’m trying my first BMX restoration so everything I do, I’m doing for the first time, so assume I’m doing everything wrong when it doesn’t do what I expect (add citric baths for rust removal to this…works fine…but rust comes back when warmed up).
Yes I know getting it blasted would be quicker, better and inexpensive, but it defeats the concept of being able to do the restoration at home yourself…which is kind of what this is all about. End of the day you may as well just send it off to get it resprayed entirely if you’re just want to get the job done. Outsourcing any part of the process seems to defeat the point.
(I say this as someone who’s been wrestling with this recently. When I have the space I’ll buy the sandblasting kit myself. It doesn’t seem that expensive. £150 I think should set me up with a cheap box, gun, air).
Anyway, this is exactly what happened to me. And I’ll be taking the sander and dremel to it shortly. And look forward to not having to deal with the nasty paint stripping gloop again!
Thank you! 🙏
I had a StumpJumper frame many years ago which I took to local company who stripped it and powder coated it with their next batch of whatever's (I think it may have been school chairs). It looked immense once I had applied a few stickers. Only cost me the price of a few beers.
Result!
Yeah.. i did the same thing this winter.
What i learned was that this paint-stripper don't work well on 2k paint.
I ended up applying LIBERAL amounts of it all over the frame, wrapping the entire frame in clingfilm, then let it sit for several days.
Then i took the frame into the shower where i treated it to the hottest water i had while scraping the paint off with a sharp blade.
Then it was just a matter of scuffing the surface to remove any grooves and marks before i did a coat of etch primer and then a lick of 2k industrial paint.
The bike looks amazing now, but man, i spent weeks trying different ways to remove the paint.
The aluminium polish and the drill do an admirable job polishing the frame. Impressive!
Man, I'm laughing my ass off. Clear coat would have looked awesome.... 😂
End result is dope af, great job
Great video 👍
Amazing job dude!! I've had a carrera Vengeance for so many months, and wanted to blast it in the last few weeks as I have a few ideas to make it look awesome. This video has helped a lot with tips 😁🤟
50 quid at the local blasters, then an hour with wet & dry and Scotchbrite. Just done it myself to a Claud Butler Cape Wrath frame. Paint finish is perfect like glass.
Easy to install and to use
I’m actually custom painting my trek fuel and I’m using a fine sand in my shot blaster to remove the paint but not the aluminium. Good job though.👍
Nice!
Great video. I think I’ll be popping my aluminium frame to my local car body shop for a spot of sand blasting though! That looked like a whole lot of hard work!
That tea-spill smile at the end 🤣🤣🤣🤣
I think it's not a case of having a tough time removing the paint but a what a great job that nukeproof do when they spray paint their bike frames and it looks in the polished version .
At least it finished well. Great video!
that's a good selection of fluffy ends btw
Look forward to seeing this built into a hardcore dream hard tail
That's a lot of work!
I've been tempted to do this with my 2008 Stumpjumper FSR Pro
Great job Henry but looked hard work
Now time for a cool build video ;-)
I build myself a hardtail mtb and started whit a canyon frame I got from my brother that was polished to the alloy and damn it looks good.
Thanks for that. I can safely say I will NEVER do that. I’d be sobbing with frustration the whole week if I did.
It could be fun to know the frame weight before and after.
I'd say 150 grams
I weiged my frame before after.
1715g before
1695g after
Only 20g damnit
@@printedprops8730 20g only I thought it would be in 2~300g range.(1 can of paint)
Soak it in DOT5.1 and wait 24 hours, will definitely strip the paint. I found out because after bleeding my brakes, I didn't clean the calipers and frame :(
DOT fluid also destroys aluminum eventually
@@MrJonas2255 sorry, but that is bullshit. How would you explain my Hope brakes are still intact after 8 years? Everything is blank aluminum, even the DOT reservoir and caliper.
Oh and I also have guide rs brakes, also aluminum reservoir, those are the ones where I stripped the paint because of not cleaning.
As most bike manufactures are now powder coating frames, you'll need something a little stronger than regular paint stripper something more like Benco B17 which is more industrial and then use a poli surface prep wheels to get the remaining bits of flakes off with out damaging the frame.. then de grease the frame then polish.
Brilliant video. Something about you is awesome 👌
used some paint chemical paint stripper that's about 20yrs old but still worked great, left it over night, scraped off and then repeated for each paint layer on the bike. done within 3days and minimal effort
Blimey Henry, even my nan has stopped drinking tea from a glass cup!😂
It is a pain, but worth it. Did it on my 2010 Epic until get mirror finish.
I was thinking of rawing a frame myself, and after watching this, im glad i didn't...🤣
For the scratches, go into a Halfords branch, and get a spray product called Flatner. This is a thick spray that you spray the whole frame with. Then, use wet and dry paper to rub it down. This will get rid of all marks on the frame. Then you simply spray your paint over that. It gives the hot rod finish. It's worth doing.
Also, 2 coats of clear at the end!
Hi Henry
Your painstaking and seemingly never ending efforts at sanding, were an immediate reminder, of my having been through that particular 'mill'; and what it suggests for you and anyone who has persevered is 'framous' status. Whew !
ps Unable to face it again, I had the next one sand blasted and although it did leave a rough finish, the sanding to smooth was much easier.
The painting; well that's another story.
Peter
Was thinking about doing this. Change my mind.
Good stuff, that nukeproof paint!
I feel like the decals should be added back on once it's built back up... But definitely keep the "UKEPROOF". :P
Or pukeproof😂
Fooookproof paint
It's important to share failures too (something academia could also profit from). I started stripping my frame today, results came nowhere near my expectations, but now I see that's normal :D
great vid and anyone else notice henrys little muck tash at 6:00 haha
I sanded as much of the top layers of paint off with going through to the frame surface... THEN I used the stripper. Got pretty good results.
did the same procedure like henry there.. i feel you
I recently did it with sandpaper. Took ages.
Don't recommend it.
@@Redoralive same here. but it was a pleasure anyway :p got a whole new connection to my frame now :)
I stripped down my commuter bike 35 odd years ago and the Nitromores I used then is nothing like the weedy excuse for paintstripper they sell today!
It took all the paint off without a problem except I didnt rinse it down very well and the new paint took an age to harden properly! (I was young!)
Most things that were very good for the task of preparing surfaces for paint cannot be used today because of those silly government regulations prohibiting the use of caustic, acidic or carcinogenic substanses which work wonderfully but are not so good for the envionment, (or your skin/general health!) so we have to either be licenced to use such things or put up with inefective "paintstrippers" which can't dissolve sugar let alone a good paint!
If you're lucky enough to have, or have access to, a bead/sand blasting cabinet, thats the best thing to get all the paint off even in those rippely welds and other awkward areas that are such a pain!
For producing a polished finish use emery or wet'n'dry paper and keep it wet! Yes, it can be messy but the paper will last longer and you'll get better results. After the paint is off start with 400, then 800 and progress up to a 2000 or even 3000 grade of paper before trying to polish. Then use a rotary buff or mop with a metal polish on a power drill for the large areas and finish off the awkward spots with the dremmel. Always use eye protection when doing this!
Results will vary depending on the alloy used in the frame but overall results should be good. Finally, finish off with a good coat of laquer to preserve your hard work!
Wouldn't the laquer have trouble sticking to the smooth polished surface? Usually when you spray something you want to rough up the surface slightly to allow for proper adhesion.
@@MrJonas2255 I used to work in a polishing shop and to preserve the polished finish we always laquered the door furniture ( and other items exposed to the elements) to stop tarnish and corrosion. When these came back as repeat customers, the first job was always to strip the old laquer off. so I guess it sticks pretty well!....
Besides why would you rough up a polished surface if you just spent many hours polishing it???
@@MrJonas2255 If you properly de-grease it, it works well on polished surfaces, besides why would you destroy many hours of work polishing it just to rough it up again??
I use a paint stripping company that uses walnut shell blasting to remove paint from aluminium and can be glass bead blasted after walnut shells to get an even finish. Can't use glass beads at first as that would leave the metal surface too uneven, Takes a few minutes to do, just need the right machine!! They also do sand blasting for steel frames. We only sand Carbon fiber frames.
I just watched Neil do a whole video on being more environmentally friendly.... Do you guys try and offset each other?
I remember respraying a 40 year old Raleigh frame, a cassic Nottingham built Exage with Reynolds tubing, man they painted those things well back then, they used 15 layers of paint. Took me three days!
Took me 3 days. First I burnt the paint off very carefully. Then used some paint remover at the corner and leftover places. I did the paint remover twice. Than began sanding.
But at the end it looks sweet.
As has already been mentioned, Media Blast the frame at your local garage etc. If you tell the garage all you want to do is rent the cabinet from them, and do it yourself, you will save an hours labour charge. I did mine for £25 at my local metalworks factory.
Use Dichlorometan mate wrap some papper towels around the frame soak them in dichlorometan, cover with clingfilm, and in 20-30min you should get a really great clean frame.
Oh man, talk about the hard way! I owned a custom powder coat shop years ago and I used methylene chloride, purchased most commonly as "aircraft remover" (I bought it in commercial bulk but it's the same active chemical). Works fast and very quickly
It's hard to find a stripper with that active ingredient anymore I can't find any
@@leegarrett5469 look up Benco B-17. It's available. Expensive, but available
@@dreadsanddirt5966 thanks I'm googling it now
Hey GMBN tech Henry! Now you are an expert you can strip all of Doddy's restoration project frames for him! Ride ride ride!
I stripped a lot of 20” frames back in my street and vert days... then after that, dipped them chromemolly frames into 20 gallons of Pepsi then did a light wash after they dried and rusty then put all the parts back on for that nasty ass bike look we all loved in the late 90’s
I've just down mine with wickes own brand paint stripper it says it takes an hour on the bottle but I left I over night and it came off so easily, definitely alot easier than sanding and only £7 for a liter which is easily enough for one frame
I was about to embark on a similar journey last year, and I'm glad I did not. instead, I asked a local frame builder if he knew anyone who could do it professionally: it took a few bucks (like 15€) and a few days to have a steel frame perfectly sandblasted (I think they actually used tiny glass beads). I then brought it to an industrial paint shop where they powdercoated it.
If you want a gloss finish, then you begin the sanding down and polishing process, otherwise you leave it like that: the sandblasted finish is really interesting! I think I'll do it, sooner or later, to my current aluminium hardtail. And I'd mask the "decals" and polish them shiny, I think that would make for an interesting look!
On cars would usually scuff the paint and use mostly the rustoleum aircraft grade paint remover. Hard to get places a little heat works too
I'm doing the same thing with my redline frame. I'm going through the same struggles.
sanding with a course grit before applying the stripper helps too, but most commercial paint strippers aren't as strong as they used to be.
I’m just gonna roughen up the old paint with sandpaper and Matt black it. You can also buy sandblasting connectors for pressure washers. Used to hire them out years ago.
Shot blasted done in minutes. Also the surface finished would be good and ready to be polished.
@01:00 I’m fairly positive that somewhere there’s a guy called Uke silently going ”Nooooo...”.
I’m pretty sure there are a few guys wishing that he’d just put a “P” at the start of it...
And the sponsor says “NO!” 😂
Taking the P
I’m doing mine at the mo, not going to lie.... it’s an absolute ballache
I took my bike down to bare aly a few years ago, it was shit. Long and arduous and I'd never do it again, paint is way too good nowadays and paint stripper is weak...
The only thing that actually ended up working was sandpaper and determination!
Get it professionally stripped, it's well worth it!
you could of course buy some Methylene Dichloride (oddly ebay is a good place.) just put in over kitchen roll wrapped around your frame parts and cover that with cling film. it comes off great.
Aircraft paint remover. I used it to strip 3 whole bikes in one day. Very hard sturdy SANTA CRUZ paint. It took a few coats but way faster than getting it off with sandpaper, and you don't take off aluminium.
which kind?? i cannot find any that has methylene chloride anywhere
@@driftadvocate1839 Klean-strip QAR2000. It’s very important to do it while the air temperature is around 75 degrees.
Wish I found this sooner! the paint stripper I'm using to take the paint of my 540s rockrider is rubbish. Should have started sanding it from the start.
In Canada we have “Circa 1850” stripper which is creepy good. You dab it on and it bubbles up in the same pattern you dabbed it on three minutes later. I did this to a Brodie Bigshot back in the day and used a Dremel brass brush on the welds. NOTE- it is SUPER toxic! Get a whiff and you’ll know immediately. AND- don’t do the brass brush Dremeling inside, I was catching 1cm bristles in my feet for a year after. The frame looked great after.
Use aircraft paint stripper, apply liberally, use plastic scraper. Apply another coating liberally again, wipe clean with acetone soaked rags.
Finnish it with “Purple Polish”.... hard work but worth it, it will look like chrome
Strip and clean/ poly disc on angle grinder. then wire wheel on tight spots at welds.
Then light sand
Poly disc is less corse at removing metal than sander but very good at removing paint.
Mothers works great BUT it really pulls the 'dirt' off of the metal, leaving the black residue you see. Best to use many throw away rags or paper towels for the first few passes until a shine starts to develop. Otherwise you'll go through a lot of polishing wheels.
angle grinder with a prep wheel would be my choice of weapon, it'd actually be able to deal with those weld beads with some effort. If you really want to go full manual labour then steel wool after the sanding. Or take the advice of some other comments and pay for a material blaster. This is a case where having the right tools for the job saves a lot of time and gives a better result.
You should use aircraft paint stripper. I tried the nitromors. poured on a very thick layer just to get it working but it worked nothing compared to aircraft paint stripper. Unfortunately I've run dry and no way near a complete bike frame.
I would have kept the "ukeproof" its hilarious!
I soaked mine with paint stripper and left it for 24 hours, worked like magic.
stripper name would help
Should have used a mini shot blaster , from Amazon lol 🤣
