I think they made these benches out of blocks and render but I could be wrong.

Does anyone have any idea of what the meterials might be?

Does anyone know of a good workable smooth hard render that bonds well to concreate?

I hope you can help.

Please see photos.

it looks like cast concrete to me, They use timber to form the shape and then fill it with concrete
