Artificial Rock Colours

[Rodney Fletcher]

Hi all

I was wondering is there anybody else out there who also use concrete oxides to colour artificial rock etc ?

I have been creating Artificial rock for over 20 years now, I have always used oxides, water and polymers finished off with 2 coats of special concrete sealer, a great colour system for concrete colour washings. Until late the companies over here in Australia have changed the Polymer they have taken the main ingredient out and gone with a more Bio-friendly ingredient which I argued would possibly not work.  I am a bit sceptical thought this would be a great Discussion to see what others use for there colouring methods.
