I want to paint some external black plastic drainpipes and also some black painted cast iron drainpipes. What paints brands and types can i choose from? Thanks.
Assuming the plastic drain pipes are UPVC, they are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Rust-Oleum CombiColor Multi-Surface.
This can be mixed to many RAL, NCS or BS colours in a gloss finish.
Assuming the painted iron drain pipes are also clean, dry, sound and prepared as detailed in the technical data sheet with no bare metal areas exposed the same paint could be used.
We would recommend testing for compatibility and adhesion on a small area prior to full application.
