Acrylic I tend to associate with paint and plastics.


 From satellite imagery I simply used 'paved' where I can determine it 
is not a 'natural' surface.


Only some ~600 uses of DecoTurf.

Only some ~20 uses of Hardcourt.

Surface is used some 31,000,000 times so the above 2 may not be rendered 
anyway being such a small proportion.. possibly lumped into 'paved' if 
anyone bothers.
