Can anyone guide me towards a good supplier of Vermiculite for cement mixes? I've looked on the web and it seems to be for horticultural purposes. Does this matter? What spec do I need to look for? I'm guessing that it's not the "exfoliated" stuff I'm looking for that you can get from builder's yards? The price seems to be about £12 for 10L on the web?
