Polysweep Polymeric Sand is a proprietary blend of advanced polymers and ASTM C-144 joint sand. Once activated with water, PolySweep creates a semi-solid sand joint that is superior in strength and very durable to withstand extreme heat/cold and freeze/thaw cycles. PolySweep is made using a unique technology that achieves a long-lasting balance between flexibility and cohesion to prevent sand loss, resist weed growth and deter insect infestation. PolySweep is easy to install in four simple steps and once completed will reduce overall surface maintenance. Surfaces with PolySweep installed can be sealed with Trident sealers once the surface is dry for 24 hours after water activation or rain. Available colors: tan, gray, fieldstone, platinum and black.
