{"product_id":"natcem-tank-25kg","title":"Natcem Tank 25kg","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eNatcem Tank is an environmentally friendly waterproof mortar with rapid strength gain, designed for tanking, damp proofing and waterproofing applications from a minimum thickness of 10mm. Formulated from a blend of natural cement binder, retarder and specially selected graded aggregates passing a 2mm sieve, it contains no chemical additives and requires only the addition of water. An extended setting time of 55–60 minutes at 20°C provides longer workability than faster-setting natural cement mortars, making it well suited to larger tanking projects. Achieves 26 MPa compressive strength at 28 days, sets underwater and can be used down to 0°C including in freezing conditions. Can be overcoated within one hour of setting. Supplied in 25kg bags.\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\"\u003eWaterproof, sulphate resistant and resistant to chloride penetration\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eExtended setting time — 55–60 minutes at 20°C for greater workability on larger applications\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSets underwater and usable down to 0°C including in freezing conditions\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e26 MPa compressive strength at 28 days, with strength continuing to develop thereafter\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eHigh chemical resistance and low carbon footprint\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\"\u003eCan be overcoated within one hour of setting\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eEnvironmentally friendly natural cement formulation\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 x 25kg bag with 3.6–4 litres of water produces approximately 12.5 litres of mortar\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCoverage: approximately 1m² at 10mm depth per 25kg bag\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMinimum application thickness: 10mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWhen applying a finishing plaster, use Thistle Board Finish or Lime Plaster — do not use Multi-Finish Plaster\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDo not apply additional water during finishing — may cause surface cracking\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eOnce setting has started, do not remix or smooth the surface\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eShelf life: minimum 12 months in dry storage conditions\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAlways refer to the Natcem Tank Product Data Sheet before use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Natural Cement","offers":[{"title":"Default Title","offer_id":57433722454348,"sku":"BM06255","price":34.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/natural-cement-mortar-natcem-tank-25kg-1235060685.jpg?v=1777657593","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/natcem-tank-25kg","provider":"Construction Supplies UK","version":"1.0","type":"link"}
