Julia Posted September 4, 2019 Share Posted September 4, 2019 Not specifically railway, but I'd like to repaint the storage box that I use for my locos so it blends in a bit more under the layout. The material it's made from is Polypropylene, according to the little 5 in the recycling logo embossed on the bottom. What's the best paint for Polypropylene? I'm guessing I'm gonna need a primer of some kind? Any suggestions? Thanks J Link to post Share on other sites More sharing options...

Everything polypropylene that I've tried to paint (or stick) has resisted very successfully. Regards, John Isherwood. 1 Link to post Share on other sites More sharing options...

RMweb Premium Andy Hayter Posted September 5, 2019 RMweb Premium Share Posted September 5, 2019 And despite what those sites will say, you are unlikely to get a good and permanent coverage. It took the industry years and millions of pounds to develop grade of polypropylene (PP) that could be painted for use in the automotive industry. This involved the use of special and relatively expensive additives in the plastic to anchor the paint. Those additives will not be present in your box I am afraid to say. If you do find a spray can that says it is suitable for use on PP, you will find it's a colour for use on cars and it means for use on PP based bumpers and bodywork - ie. those grades that have the special additive. 1 2 Link to post Share on other sites More sharing options...

Perhaps you could put a wrapper around it? Fablon or similar. Link to post Share on other sites More sharing options...
Campaman Posted September 16, 2019 Share Posted September 16, 2019 Another option similar to the wrapping idea is that you can get coloured and patterned rolls of Duck tape from Hobbycraft Link to post Share on other sites More sharing options...
Tony W Posted September 16, 2019 Share Posted September 16, 2019 Not very helpful I know but it might save you a lot of time and expence if you bought a more suitably coloured stockbox. We ended up relaying half our layout when we came across the problem of painting polypropylene track bases. One industrial painter did say he could do it but we'd have to vacate the clubhouse for about 12months until the fumes had subsided!! Tony Link to post Share on other sites More sharing options...

That would actually stand out more than the storage boxes... Shame it looks like paint isn't going to stick to polyprop. *DOUGH* Thanks to everyone for their ideas.
