Any ideas for render/paint HDPE Pipe

Any ideas for render/paint HDPE Pipe

(OP)
Hi

Currently over seeing the big of a large mountian bike course build, we have buried a 2m dia section of HDPE pipe but now require to either render/paint it to look like stone of concrete.

Any ideas???

RE: Any ideas for render/paint HDPE Pipe

Have you considered concrete or fiberglass facade stamped or hand shaped to look like rock?  Is Larson (I think that was the companies name)around any more?  They used to provide this type of work for zoos and other type of things.  

RE: Any ideas for render/paint HDPE Pipe

Paint will not work. HDPE has a very low surface tension, meaning that you will not be able to coat it with anything permanantly, as whatever you paint onto the pipe will crack and peel off. The thermal expansion of HDPE is more than likely going to be more than that of your coating. The thermal expansion of HDPE will probaly make the coating crack and will also make a coating useless.

You will have to cover the HDPE with a facade of some sort.

This probably won't work, but ADS makes a grey triple wall (smooth exterior and interior) pipe. No one would ever mistake it for stone or concrete, but it might blend in better than black pipe.

The problems are they only go up to 60" (1.53 m) and you'd have to remove the old pipe.
