ARDEX Multiprime provides that reliable base, preventing bond failures on porous substrates by creating an optimal surface for subsequent ARDEX systems. It’s the critical first step for confidence in your build.\n    \u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection class=\"product-content-section\" aria-labelledby=\"positioning-heading\"\u003e\n    \u003ch3 id=\"positioning-heading\"\u003eWhy this product exists\u003c\/h3\u003e\n    \u003cp\u003eARDEX Multiprime is a water-based primer formulated to enhance the adhesion of approved ARDEX products to a range of porous substrates. It seals and prepares surfaces like concrete, screed, and autoclaved aerated concrete (AAC), promoting a stronger bond for membranes and finishes. Its low VOC and quick-drying properties support efficient work cycles for both internal and external applications.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection class=\"product-content-section\" aria-labelledby=\"specs-heading\"\u003e\n    \u003ch3 id=\"specs-heading\"\u003eThe numbers that matter\u003c\/h3\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n\u003cstrong\u003eDrying time: 15-30 minutes\u003c\/strong\u003e at 23°C and 50% relative humidity.

Ensure the contents are well-shaken before use. For highly porous substrates like AAC, a second coat is necessary to achieve the desired surface sealing and adhesion promotion. Clean all equipment with water and detergent immediately after use, before the product has a chance to dry, as cured material requires mechanical removal.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection class=\"product-content-section\" aria-labelledby=\"applications-heading\"\u003e\n    \u003ch3 id=\"applications-heading\"\u003eWhere this product excels\u003c\/h3\u003e\n    \u003cp\u003eARDEX Multiprime provides essential adhesion and surface preparation in critical build-ups:\u003c\/p\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n\u003cstrong\u003eWet areas: bathrooms, showers, laundries, and kitchens.\u003c\/strong\u003e Here, it serves as a primer for waterproofing systems on concrete, render, and screed, ensuring the membrane bonds securely to the substrate.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eRoofing: concrete roofs and membrane-covered tiled areas.\u003c\/strong\u003e This primer is effective as a reprimer for built-up or filled areas, preparing the surface for subsequent layers in a robust roofing system.\u003c\/li\u003e\n      \u003cli\u003e\n\u003cstrong\u003eBalconies, podiums, door\/window reveals, and flashings.\u003c\/strong\u003e Its role as a reprimer in these exposed areas contributes to the long-term integrity of waterproofing and sealing applications.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/section\u003e\n\n  \u003csection class=\"product-content-section\" aria-labelledby=\"system-fit-heading\"\u003e\n    \u003ch3 id=\"system-fit-heading\"\u003eHow it fits in a real system\u003c\/h3\u003e\n    \u003cp\u003eThis product consistently appears early in the build sequence, typically after initial substrate preparation and crack sealing, but before the main waterproofing membrane is applied.
