{"product_id":"natcem-waterstop-5kg","title":"Natcem Waterstop 5kg","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWaterstop is an environmentally friendly, rapid setting water-plug mortar designed to stop leaks in seconds. Once mixed with water, it begins to set in just 90 seconds and is fully set within 2½ minutes at 20°C — making it one of the fastest acting leak-sealing mortars available. Suitable for sealing leaks, stopping water ingress and use in direct contact with potable water, it is DWI Regulation 31 approved (ref: 56\/4\/1217) and tested to BS 6920 for effect on water quality. Contains no chemical additives, requires only the addition of water, and sets underwater — usable down to 0°C. Can be overcoated within one hour of setting. Supplied in a 5kg tub with no limited shelf life when stored in dry conditions.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eRapid setting — starts to set in 90 seconds, fully set in 2½ minutes at 20°C\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eStops leaks in seconds — simply apply and hold in position until set\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSets underwater and in cold conditions down to 0°C\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDWI Regulation 31 approved for contact with potable water (ref: 56\/4\/1217)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTested to BS 6920: Effect on Water Quality\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eNo chemical additives — just add water\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eExcellent adhesion to roughened substrates\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCan be overcoated, covered or painted within one hour of setting\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eEnvironmentally friendly — no limited shelf life when stored correctly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMix ratio: 1 part clean water to 3 parts Waterstop — knead to a putty consistency within one minute\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eYield: 1 x 5kg tub with approximately 1.9 litres of water produces around 2 litres of mortar\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDo not use on frozen or overheated substrates (outside 0°C–30°C range)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFor large leaks, seal in small sections starting from the top and working downwards\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSetting time can be slowed with cold water in hot conditions, or accelerated with warm water in cold conditions\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAlways refer to the Waterstop Product Data Sheet and Safety Data Sheet before use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Natural Cement","offers":[{"title":"Default Title","offer_id":57425701405004,"sku":"BM06259","price":39.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/natural-cement-waterproofing-natcem-waterstop-5kg-1235040071.jpg?v=1777636010","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/natcem-waterstop-5kg","provider":"Construction Supplies UK","version":"1.0","type":"link"}
