PolyFlex DS – Black / Gray

PolyFlex DS is a versatile thin penetrating polymer designed to re-bond cracked and rutted asphalt or concrete. It is applied using either the Roklin Vari-Flo Polymer Dispensing System for asphalt or the Roklin Concrete Welder Polymer Low Pressure Dispensing System for concrete. PolyFlex DS restores the strength of the substrate by penetrating and re-bonding cracks, sealing surfaces to prevent further damage, and allowing for rapid repairs ready for traffic within 20 minutes.

PolyFlex DS Rapid Concrete & Asphalt Crack Repair kit includes a dual-cartridge filled with repair compound and an application gun. The kit is designed for quick and effective repair of concrete and asphalt cracks.

Surface Preparation

  • Remove loose and unsound material

  • Blow crack clean with dry compressed air

  • For large cracks, fill with 30 mesh or larger sand

Mixing Procedures

Co-reactive “A” and “B” components are transferred from containers through proportioning pumps (1:1 ratio) to the dispensing gun. The mixed material is then dispensed into repairs.


For best performance, install at ambient temperatures between 10°F to 100°F and material temperatures between 50°F to 75°F. Do not apply during rain or on wet surfaces. Always read the Material Safety Data and Installation Instructions before using the product.


  • Penetrates and re-bonds thin, wide, or deep cracks

  • Waterproofs and protects from freeze, thaw, or spalling

  • Smooths rough surfaces and restores traction

  • Solidifies in less than 5 minutes, ready for traffic in 20 minutes

  • Successful repairs in cold or hot weather

  • Non-flammable, low odor

  • Chemically resistant to acids, alkalis, salt, gasoline, diesel fuel, lubricating oils, and antifreeze


PolyFlex DS is available in black for asphalt and gray for concrete. This product re-bonds cracked surfaces, restores strength, and seals to prevent further deterioration. The polymer is applied using specialized dispensing systems, with large cracks filled with sand before being saturated with PolyFlex DS to form high-strength polymer concrete.


  1. Large Crack Repair: Remove loose material, blow clean, fill with sand, and flood with PolyFlex DS.

  2. Hairline Crack Repair: Blow out cracks with dry compressed air, flood with PolyFlex DS, and broadcast sand on cured liquid for a high traction surface.

  3. Spider Cracks: Shot blast or sand blast deck surface, flood with PolyFlex DS, and broadcast sand into the cured liquid.

  4. Restoring Traffic: Traffic can resume within 20 minutes of completion of work, reducing crew exposure to oncoming traffic.
