    The ratio is 2 bags of Vermiculite to 1 bag of cement. The Vermiculite and cement go into the mixer and then you’ll add about 2 – 5 gallon buckets of water, until you reach an oatmeal consistency that you can trowel easily.
    I used the 4 cubic foot bags (big bags) (two of them) with one 94 lb bag of portland and it came out excellent. I bought a full pallet from RoyalSwimming pool (link below),, ran short and reached out to my local pool company - they sold me a few bags at about the same price (if I remember right about $20 per bag.
