Postcrete for a pad for a BBQ

[iwaters]

I've got a large cast iron BBQ I want to position on soft earth. I want to lay a concrete pad to support it.

I've got quite a few bags of postcrete left from a deck I built. I know the finish won't be the same but I have a rubber mat to cover it.

What's the best way of using this. Build a form, half fill with water and then pour the bags of concrete in. Or should I mix in buckets pour and smooth?

It will be a small area. Max 1 x 0.6 m

I don't think you can mix and place postcreteas a separate operation, I think it has to be mixed in place due to the working time. I'd go for the water and then powder option personally, as per instructions.
