Hammerite removal

[smashweld]

I'm thinking wire brush on a grinder.....

would the knotted or normal type be better? can't decide which would clog up faster....


any other magical hammerite removal greatly recieved!

Horrid stuff, its fallen off most of the things I have ever painted with it. Slam a door or try shouting at it, you may be able to scare it off.

Depends largely on what you are removing it from..

a 40x40 box section frame...

If it has hardened properly a needle scaler might take some of it off, otherwise a knotted wire wheel on a grinder should work.

For any inaccessible areas starchem paint stripper should work.

For paint mechanical paint remover I prefer the strip and clean discs on an angle grinder, they don't clog, act fast and will also properly clean light rust unlike a wire brush which just polishes it.

Strip and clean discs?

If its box, how does hammerite respond to heat? Blow torch and scraper may do the bulk, leaving a shorter abrasive clean up?

 

[julianf]

...or maybe just save yourself a load of time and take it to a blaster?

Then yes, blowtorch and scraper will get through the eggshell finish and make chemical stripping much more effective.

Old school Nitromorse would have it off in the sting of an eye but I doubt if any current off the shelf stripper would touch it otherwise.

As has been mentioned previously, you can still buy DCM easily, just not under the nitromores brand name.

Not seeing where. Is it a secret?

Pure acetone takes it off with a bit of elbo grease.

petrol will soften it (guess who painted a petrol tank with hammerite )

No, i just didnt mention, as it seems to come up every other week! : ) [exaggeration, but you get the idea!]

Go on ebay and search dichloromethane (check the spelling)

You can buy it in 25ltr tubs!

(basically, old nitromores, it seems, was just DCM, and a binder to stop it running away)

Strangly, its heavier than water, and wont mix with water, so you can put it in a tub, with a water layer over the top, to stop it all evaporating.


You can also buy it from, i think, RS, in a spray can - cant remember the detail, but search this forum, and youll find the post - i think a couple of months ago

Cheers all. Great tips!

Depending on how well it has stuck to whatever you want to strip you could try a wood chisel, my brother in law used this method to get most of it off his lathe

The starchem paint stripper still contains the good stuff, anywhere that sells body shop supplies should stock it - strictly for professional use of course!
