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 ru nning 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.

You either skip compaction and the joint never locks, or you compact and risk cracking the stone. NOCO removes that choice. 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. 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. NOCO Specifications Product Type No compaction polymeric jointing compound Bag Size 50 lb Colors Iron Grey and Desert Tan Joint Width Range 1/4 in to 4 in Joint Types Regular and false joints Mechanical Compaction Not required Coverage, Joints Under 1/2 in Up to 120 sq ft per 50 lb bag Coverage, Wide Joints (Flagstone) 10 to 40 sq ft per 50 lb bag Traffic Rating Pedestrian, light vehicular, heavy vehicular Installation Areas Normal and high humidity Surface Level Flat and sloped Approved Surfaces Natural stone, flagstone, large slabs, highly textured surfaces, clay pavers, concrete pavers, concrete slabs, porcelain tile, wet cast pavers Base Types Hard base, and cement or sand base Warranty 20 years, limited Manufacturer Techniseal 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 10 to 40 sq ft per bag on wide flagstone joints. On irregular flagstone, plan against 10 sq ft per bag on wide flagstone joints and you will not come up short. Techniseal calls for at least 50°F for 48 hours after installation, a minimum joint depth of 1 1/2 in, and 7 days before sealing. Show more
