Plastic Coated Radiator Bubble...

[zhacwuyts]

Hi a friend of mine has a designer radiator, like the old cast iron type, which has white coating. There is bubbling under the coating and some small cracks at the edges. Any ideas how I can repair this?

Cheers!

Sounds like the radiator is corroding underneath the enamel coating. It'll need to be scrapped back and treated. Then she could apply enamel paint herself, which could look a bit poor. Better still get someone who re-enamels baths to spray it.

Cheers Dan, I presume a couple of coats of Hammerite enamel paint will do the job? I'll crack on and try it.

Remove the rad and get it sandblasted and powder coated. Will cost about £20 - 30

Tamz, I don't think you'd get it done that cheap! I have taken a rad to a car spray shop once. Cost me £80, and that was a brand new cast iron rad, so no sand blasting or the like.

Zhac - Yes that will do it, but it'll never look anything special. I'd be tempted to have it sprayed as Tamz suggests. Just expect to pay quite a bit.

cheers guys...I'll scrape it back and check underneath first..its on a bottom edge so I reckon for the moment a spray will do. I'll fish around for someone to sandblast it.
Thanks guys

No prob. Good luck!

There is a place near me who do it. If it is a small thing like a rad they do it for £25 cash. The sandblasting takes 5 minutes but you have to leave it for powder coating.
Last thing i had powder coated was Alumasc gutters and downpipes in RAL 3000. Worked out at £12 a length which was cheaper than buying it prefinished.

Really? That's a good contact...no way I'd get any where near that price.

It just proves its not what you know but who. Or a mix of both

never go to a car sprayer, they will have yur pants down.

go to a cabinet sprayer, powder coater etc. if you cant find one ask a joiner where to go. they will spray a front door around here in gloss acrylic for £35 cash.

A friend of mine has these rads that, i think, he bought from Screwfix about 5 years ago, or maybe even less.

They are doing exactly the same along the top and down by the inlets.

Sounds strange but quality is not what it was especially were screwfix is concerned

imho

Could try adding some leak sealer to the system
