Hi,
I intend to paint the walls on the under stairs cupboard.
The gas meter and copper gas supply pipes are visible and I'd like to paint the pipes white.
Is there a paint that IS suitable for copper (or is there a type of paint that should NOT be used on copper pipes?)
I'd be very grateful for any advice or help.
Cheers
CJ

Hi steameraeg
Yes to oil based paint eg undercoat, no to water based paint eg emulsion.
Regards S

Thanks for the info about oil based undercoats, S.
Just as a matter of interest, can you tell me why is this?
I ask because other websites have people who seem to have had good experience of using water based paints.
Cheers and thanks again,
CJ

Hi steameraeg
The issue with water based paints is that they do not adhere well to non porous surfaces especially if there is condensation likely to form on the pipes.
Regards S

Aha, now I get it!
Thanks again,S, for the help and info, off now to find an oil based undercoat, must have some - somewhere in the garage!
Cheers

I have used water-soluble Hammerite primer for non-ferrous metals, outside, covered with the standard Hammerite xylene based product. After two years I cannot find a fault.

My suggestion to OP, would be to use the same primer eg: https://www.duluxdecoratorcentre.co.uk/ ... &v=5084909

than cover it with gloss or satin pain, and only then - if you really have to cover it with emulsion, but bear in mind if you use it on the how water/heating supply - emulsion will crack.

Choose A metal paint and primer based on enamel or oil. If you're painting a pipe, make sure both products are compatible. Paints and primers for metal surfaces are generally available in both spray-on and paint-on varieties.
