About this item
- No vibrating plate needed. Techniseal states NOCO does not require mechanical compaction. Surface compaction remains possible, but it is no longer mandatory. On irregular flagstone that alone can save a day of labor and a broken stone or two.
- High compressive strength. Skipping compaction does not mean a weak joint. NOCO is formulated for strength without the plate.
- It stays flexible. NOCO follows soil movement rather than fighting it, which is what prevents joints crumbling through freeze and thaw cycles.
- It adheres to the stone without contracting. Techniseal specifies that it bonds strongly to the inner walls of pavers and stones and does not shrink back, which is where gaps and hairline failures usually start.
- It flows down the joint. The formula is built to spread easily and run smoothly and uniformly into irregular joints rather than bridging over them.
- Rated for heavy vehicular and humidity. Techniseal lists pedestrian, light vehicular, and heavy vehicular traffic, plus high humidity environments and sloped terrain.

Why NOCO?
The No Compaction Jointing Compound Built For Flagstone And Natural Stone
Flagstone is the install where conventional polymeric sand causes the most trouble. You either skip compaction and the joint never locks, or you compact and risk cracking the stone. NOCO removes that choice.

Description
Description
The No Compaction Jointing Compound Built For Flagstone And Natural Stone
NOCO is a high compressive strength polymeric joint made for flagstone and other paving materials where running a plate compactor is impossible, impractical, or simply too risky for the stone. It does not require mechanical compaction at all. It handles joints from 1/4 inch to 4 inches, stays flexible so it follows soil movement through freeze and thaw cycles, and carries a 20 year limited warranty. Techniseal calls it the first true alternative to mortar and stone dust.

- Impervious jointing. Once cured it repels weed growth and insect infestation, the two things that ruin a stone patio over time.
- Works over both base types. Techniseal approves NOCO on hard base and on cement or sand base installations.

The coverage spread on NOCO is wide because flagstone joints are wide and irregular. Techniseal gives up to 120 sq ft per bag for joints under 1/2 inch, dropping to 20 to 40 sq ft per bag once the joints get wide. On irregular flagstone, plan against the low figure and you will not come up short.
