{"product_id":"newton-flexproof-106-nv-7-5kg-pourable-movement-joint-waterproofing","title":"Newton FlexProof 106 NV 7.5kg | Pourable Movement Joint Waterproofing","description":"\u003cp dir=\"ltr\"\u003eMovement joints are built into concrete slabs, decks and floors so the structure can expand, contract and shift without cracking. But a gap designed to move is also a gap water can travel through, and sealing it is a challenge: the sealant has to stay flexible enough to follow the movement without tearing, splitting or pulling away from the sides. Newton FlexProof 106 NV is made for exactly that job on horizontal surfaces.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe NV variant has a lower viscosity than the thicker X1 paste, so instead of trowelling it, you simply pour it straight from the foil bag into the joint, where it flows to fill the space neatly. It cures into a tough elastomeric seal and is the most flexible of the FlexProof 106 range, with an elongation at break of up to 450%. It bonds superbly to concrete and most other building materials, including block, screed, metal, plastic, timber and glass. It stays watertight against water pressure even when the joint moves by up to 20% in expansion and compression and 10% in shear, and it isn't affected by the high alkalinity of fresh concrete.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAs a single-component product, there's no mixing and no pot life, and a rain-tight skin forms within minutes, so a passing shower won't spoil the work. Once cured, it performs from -40°C to +90°C. It's ideal for sealing horizontal movement joints in slabs, podium decks, basements and floors, as well as joints between different materials that move at different rates.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eLow-viscosity formula pours straight from the bag into horizontal joints\u003c\/li\u003e\n\u003cli\u003eExceptionally flexible, with up to 450% elongation at break\u003c\/li\u003e\n\u003cli\u003eStays watertight with up to 20% expansion and compression and 10% shear\u003c\/li\u003e\n\u003cli\u003eResists both positive and negative side water pressure\u003c\/li\u003e\n\u003cli\u003eRain-tight skin forms within minutes of application\u003c\/li\u003e\n\u003cli\u003eExcellent resistance to the high alkalinity of concrete\u003c\/li\u003e\n\u003cli\u003eStrong bond to concrete, block, screed, metal, plastic, timber and glass\u003c\/li\u003e\n\u003cli\u003eSingle component, with no mixing and no pot life\u003c\/li\u003e\n\u003cli\u003ePerforms from -40°C to +90°C and is VOC-free\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eGood to Know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eSupplied as a 7.5kg foil bag inside a tub, grey\u003c\/li\u003e\n\u003cli\u003eBest suited to horizontal surfaces and movement joints; for vertical joints and construction joints, the thicker X1 variant is more suitable\u003c\/li\u003e\n\u003cli\u003eIdeal for pouring into joints of 18–72mm wide; for narrower joints, decant into an empty cartridge and apply with a mastic gun\u003c\/li\u003e\n\u003cli\u003eInsert a foam backing rod roughly 1.5 times the joint width, then fill to a depth of half the joint width\u003c\/li\u003e\n\u003cli\u003eApproximate coverage per bag in movement joints: around 21m of a 20mm joint, 9m of a 30mm joint, or 5m of a 40mm joint\u003c\/li\u003e\n\u003cli\u003eOn flat surfaces, apply 2.0mm thick at 3.0kg\/m², giving approximately 2.5m² per bag\u003c\/li\u003e\n\u003cli\u003eMask both sides of the joint with tape for a neat finish, and smooth with a soapy wet knife if needed\u003c\/li\u003e\n\u003cli\u003eSurfaces must be clean, dry and free from dust, laitance, release agents, oils and paint\u003c\/li\u003e\n\u003cli\u003eUse a suitable primer in movement joints, on porous surfaces, and where resisting water pressure from the inside\u003c\/li\u003e\n\u003cli\u003eApply between +1°C and +35°C; do not apply to wet, frozen or icy surfaces\u003c\/li\u003e\n\u003cli\u003eReady for protection boards in 20–30 minutes; cures at roughly 24 hours per mm of depth at 20°C\u003c\/li\u003e\n\u003cli\u003eNot suitable as a vehicle or pedestrian traffic surface\u003c\/li\u003e\n\u003cli\u003eClean tools with a rag before curing; xylene helps remove partly cured product\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newton Waterproofing","offers":[{"title":"Default Title","offer_id":59094488875340,"sku":"BM06393","price":225.87,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/newton-waterproofing-newton-flexproof-106-nv-7-5kg-pourable-movement-joint-waterproofing-1261386424.jpg?v=1791372689","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/newton-flexproof-106-nv-7-5kg-pourable-movement-joint-waterproofing","provider":"Construction Supplies UK","version":"1.0","type":"link"}
