C-3 Medium Grade Vermiculite

Use Palmetto Vermiculite to create a lightweight cement for a softer pool floor for vinyl-lined pools. Simply mix sand, Portland cement, and vermiculite for a smooth, soft, durable pool surface. The less abrasive surface protects your liner and is more pleasant on your feet. Product is a natural inert mineral.

How much do I need for a whole pool? For a 20’ x 40’ pool the pool bottom Square Footage is 20 x 40 = 800. Take 800 x .17 = 136 cu ft / 4 cu ft in the C-3 bag = 34 bags needed of C-3 vermiculite.
