Buying, Mixing and Applying Vermiculite to the Pool Floor
The ratio is 2 bags of Vermiculite to 1 bag of cement. The Vermiculite and cement go into the mixer and then youll add about two and a half 5gallon buckets of water, until you reach an oatmeal consistency that you can trowel easily. Leave it in the mixer for about 2030 seconds and that should do it.
