Polymeric PolySweep Brush in Sand

ProJoint PolySweep is the ultimate solution for finishing driveways, patios, and paths with narrow joints (from 1mm wide). While traditional kiln-dried sand often washes out or encourages weed growth, PolySweep contains a specialised polymeric binder. Once brushed into the joints and lightly misted with water, it cures to form a durable, elastic bond that keeps your paving stones securely in place while allowing for natural thermal movement. The “Clear Set” technology ensures a stain-free finish, making it a favorite for both professional landscapers and DIY enthusiasts working with premium natural stone or block pavers. It is specifically formulated to be weed-resistant and can withstand the force of a pressure washer once fully cured. Because it contains no Portland cement, it is easy to work with and won’t leave unsightly white efflorescence on your paving. Whether you are finishing a contemporary silver-grey granite patio or a traditional neutral-toned driveway, PolySweep provides a clean, professional, and long-lasting finish. Advanced Polymeric Formula: Cures to create a firm, flexible joint that won’t wash out or crack over time. Weed & Insect Resistant: Forms a solid barrier that prevents weed seeds from taking root and stops boring insects from nesting in joints. Stain-Free Technology: Advanced formula ensures no oily residue or staining is left on the surface of your paving. Pressure Washer Safe: Once cured, the joints are robust enough to withstand regular maintenance and power washing. Ideal for Narrow Joints: Specially designed for joints from 1mm upwards, making it perfect for block paving and tightly-laid slabs.
