How can I paint polyethylene?
Q. How can I paint polyethylene?
Carlos Lara- Mexico
A. Carlos,
To answer your question ... and all you asked was 'how do I paint Polyethylene' ... the reply is easy. Go ahead and paint!
Maybe what you meant but didn't say is HOW does one get a bond. Ah. The answer is simple. You don't.
Had you given more data, maybe I could have helped you. For instance, had you a round PE tank, then use a latex paint all over (latex being somewhat flexible) so that entire tank is painted and the paint will, so-to-speak, bond to itself, but not (very well) to the PE.
If it's a flat surface the paint would eventually come off.

A. I find the response to our Mexican friend's query about painting polyethylene to be rather "smart Alec-y". The helpful response, I believe, would be to advise him to use house exterior acrylic, which is more flexible, and will expand and contract without cracking.

Thanks, however, for providing us with this forum on refinishing topics.

Hi Steve. Thanks for the info and the helpful link! Freeman is not a smart alec, but a very kind spirit who has helped hundreds & hundreds of people here over the years -- maybe thousands. But he has been begging posters for years, as have I, to detail their own situation rather than posting an abstract question -- and I'd guess his reaction was in response to Carlos doing just exactly that anyway :-) Regards,  Ted Mooney, P.E.
