Polymeric Sand

Seal King Prolock+ is a next-generation polymeric sand engineered for strength, flexibility, and no-haze results. Perfect for paver and stone joints from 1/16” to 4” wide, its high polymer content and unique formulation create a strong, flexible bond that resists rain, wind, and freeze-thaw cycles. Applied dry into the joints, it activates with a simple one-step watering process and hardens within hours. With exceptional resistance to erosion, freeze-thaw cycles, and weed or ant growth, Prolock+ delivers a clean, lasting finish for any hardscape project. Professional-grade polymeric sand for high-traffic, demanding installations. Compatible with concrete pavers, porcelain, and natural stone. Excellent for driveways, patios, pool decks, walkways, and parking lots.
