Polymeric Locking Sand Resin Activation

Polymer binder crystals cross-linking upon water misting to lock pavers and prevent weed growth.

ACTIVATED RESIN MATRIX POLYMERIC COVERAGE • Narrow (1/8"): 65–85 sq ft/bag • Medium (1/4"): 40–55 sq ft/bag • Wide (1/2"-1"): 20–35 sq ft/bag • Water activate: 3 gentle mists

🧪

Joint Width Coverage Rate

Calculates polymeric sand requirement based on paver joint gap thickness.

Bags (50lb) = ⌈ Total Area (sq ft) / Coverage Rate (sq ft/bag) ⌉
📐

Flagstone Volumetric Joint

Irregular flagstone joint volume with wide gaps up to 1 inch.

Wide Joint Bags = ⌈ Patio Area / 25 sq ft ⌉
💧

Curing & Setting Time

Activation moisture trigger and rainfall exposure threshold.

Cure Time = 24–48 Hours  |  Rain Free Window = 24h Min
