C-3 Medium Grade Vermiculite - 28 lbs.
Medium Grade Palmetto Vermiculite creates a lighter weight, less-abrasive cement floor that is softer and easier on pools with vinyl liners. By simply mixing sand, Portland cement (found at any hardware store), and vermiculite you will create a smoother, considerably softer but equally durable pool surface that will protect the lifespan of your vinyl-lined swimming pool as well as create a more comfortable surface for your feet. Palmetto Vermiculite is a naturally inert material.
• Affordable and easy to apply
• Protects liner durability
• Great for repairing under liner
• Mixes with water, sand, and well as Portland cement
