Description
Stabilize joints on flagstone, natural stone, and concrete pavers with the Techniseal NOCO Polymeric Joint. This no-compaction polymeric jointing sand sets a stable, weed- and washout-resistant joint without a plate compactor — protecting fragile slabs, overlays, and irregular flagstone, while letting your crew finish patios faster with cleaner edges.
Product Code: 211-004 · Available in: 50-lb bag · Colors: Iron Grey, Desert Tan
Why NOCO?
- No compaction required — place, sweep, blow, and mist to set; skip plate-compactor passes that can crack flagstone or scuff overlays
- Built for irregular joints — flows into the wide, uneven gaps typical of flagstone and natural-stone installs
- Polymer-bound joint — water-activated binders form a hard-set, semi-flexible joint that resists washout, weeds, and ant tunneling
- Two finish colors — Iron Grey for darker pavers and modern hardscapes, Desert Tan for warm-toned stone and traditional patios
- Faster install — reduce job time on irregular flagstone where compaction is impractical
Color Options
- Iron Grey: deep cool-grey finish — pairs with charcoal, slate, and bluestone pavers
- Desert Tan: warm sand-tan finish — pairs with sandstone, bluestone with warm undertones, and tan-buff concrete pavers

Application
- Prep a clean, dry surface with proper slope and drainage. Sweep to remove debris.
- Sweep NOCO into joints until fully filled and slightly mounded.
- Blow off all residue from the surface with a leaf blower — hazing comes from product left on the paver face, not in the joint.
- Mist with water per label dilution — saturate the joints without flooding. Avoid overwatering.
- Cure per the technical data sheet before traffic, washing, or sealing.
- Test in an inconspicuous area before full installation.
Tips
- Work in dry, warm conditions — protect from rain during cure
- Best suited to pedestrian residential and light commercial installs — confirm vehicular use with Techniseal
- For full chemical, application, and safety information, refer to Techniseal’s technical data sheet from your dealer

Up to 120 square feet for joints under 1/2 inch wide, or 20 to 40 square feet for wide joints, depending on the material, joint width, and depth.
