Understand Resin-Based Paver Sand Application

What happens here

Begin by understanding the specific properties of the paver sand being used. The video highlights a 'resin-based sand' as opposed to a 'polymeric-based sand'. Resin-based sand cures by oxidation, meaning it hardens when exposed to oxygen. Therefore, applying it wet helps to keep the oxygen out while the sand is being worked into the joints. This ensures a proper curing process as it dries. Polymeric sands, on the other hand, are typically applied dry and then activated with water.

Goal: Learn the rationale behind wet application of resin-based paver sand.
