Lock in your hardscape joints with Seal King Prolock+ Polymeric Sand. This next-generation professional-grade jointing sand is engineered for strength, flexibility, and a no-haze finish on pavers, stone, porcelain, and concrete surfaces.
 
Designed for joints from 1/16” to 4” wide, Prolock+ is swept dry into joints and activated with a simple watering process. It hardens within hours to create a durable bond that helps resist erosion, weeds, ant infestation, rain, wind, and freeze-thaw damage.
 
Perfect for driveways, patios, pool decks, walkways, parking lots, and high-traffic hardscape areas.
