{"product_id":"build-it-postfix-20kg","title":"Build it Postfix 20kg","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePostfix is a ready to use, fast setting concrete designed specifically for erecting posts. Supplied as a pre-blended mix of cement, aggregates, sands and additives, it requires no separate batching of materials, only the addition of water on site. Once mixed it begins to set within five to ten minutes and typically reaches a strength of more than 20N\/mm² after 28 days.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIts rapid set makes it well suited to fencing, gate posts, sign posts, pergolas and similar upright fixings, holding posts firm in minutes rather than relying on the longer cure of a conventional concrete mix. Postfix is supplied in 20kg water resistant bags for straightforward handling and storage on site.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePostfix suits timber, metal and concrete posts, giving a single product for most post fixing work across fencing, gates and outdoor structures. The pre-blended formulation removes the inconsistency of gauging separate cement and aggregate by hand, while the water resistant bag protects the mix before use. It should not be used on frozen ground or in very cold conditions.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSets in five to ten minutes for a quick, firm hold on posts\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eReaches more than 20N\/mm² at 28 days for a durable, long term fixing\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePre-blended for consistent results without site batching\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSingle mix suits timber, metal and concrete posts\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eWater resistant bag protects the product and aids site storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSupplied in 20kg water resistant bags\u003c\/li\u003e\n\u003cli\u003eReady to use, requiring only the addition of clean water, with no separate mixing of cement and aggregate\u003c\/li\u003e\n\u003cli\u003eNot suitable for use on frozen ground or in very cold conditions; follow the temperature guidance printed on the bag\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Build It","offers":[{"title":"Bag","offer_id":58239632146764,"sku":"BM012349","price":4.97,"currency_code":"GBP","in_stock":true},{"title":"Half Pallet (35)","offer_id":58239632179532,"sku":"BM012349-35","price":167.3,"currency_code":"GBP","in_stock":true},{"title":"Pallet (70)","offer_id":58239632212300,"sku":"BM012349-70","price":310.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/build-it-cement-build-it-postfix-20kg-1251334593.jpg?v=1785260294","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/build-it-postfix-20kg","provider":"Construction Supplies UK","version":"1.0","type":"link"}
