On curing it forms a durable, highly alkaline, permanently elastomeric membrane that provides total waterproofing while accommodating differential movement and crack activity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSuitable for internal and external use, Cementflex provides Type A (barrier) protection as classified in BS8102:2009. It can be applied to damp surfaces by hand or spray, making it practical for horizontal, vertical and overhead applications. Cementseal Primer is required for all horizontal applications and on porous surfaces prior to applying Cementflex.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe coating resists up to 100m head of positive and negative water pressure, offers good abrasion and impact resistance, and maintains its flexibility under permanent immersion and external exposure. It also provides enhanced resistance to carbonation, helping protect the integrity of the underlying concrete.\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\u003e\n\u003cli\u003eTotally waterproof\u003c\/li\u003e\n\u003cli\u003eResists up to 100m head of positive and negative water pressure \u003c\/li\u003e\n\u003cli\u003eFlexible to accommodate differential movement \u003c\/li\u003e\n\u003cli\u003eSeamless and fully bonded\u003c\/li\u003e\n\u003cli\u003eCan be applied to damp surfaces\u003c\/li\u003e\n\u003cli\u003eOffering a tough finish that is impact resistant\u003c\/li\u003e\n\u003cli\u003eEasy to apply and is suitable for horizontal, vertical and overhead applications\u003c\/li\u003e\n\u003cli\u003eEnvironmentally friendly\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\u003eIdeal for basements and sub-structures\u003c\/li\u003e\n\u003cli\u003eCan be applied to concrete masonry and steel\u003c\/li\u003e\n\u003cli\u003eSubject to normal conditions of use, Cementflex will provide an effective barrier to the transmission of liquid water for the life of the structure.\u003c\/li\u003e\n\u003cli\u003eJ10 cementitious mortar tanking\/damp proofing or C42 repairing\/renovating\/conserving concrete\u003c\/li\u003e\n\u003cli\u003eExisting substrates and structural elements should be assessed for suitability to withstand any increase in applied loads from water pressure  \u003c\/li\u003e\n\u003cli\u003eApply only to clean sound substrates, which should be saturated but surface dry and free of back water pressure.\u003c\/li\u003e\n\u003cli\u003eCare should be taken when curing in hot sunny or windy conditions\u003c\/li\u003e\n\u003cli\u003eCementflex is not a decorative finish and may temporarily discolour until uniformly weathered.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e \u003c\/p\u003e","brand":"RIW","offers":[{"title":"Default Title","offer_id":57127700037964,"sku":"BM05761","price":228.24,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/riw-riw-cementflex-flexible-cement-based-waterproof-coating-1232467551.jpg?v=1776258273","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/riw-cementflex-flexible-cement-based-waterproof-coating","provider":"Construction Supplies UK","version":"1.0","type":"link"}
