{"product_id":"dr-fixit-mpb","title":"Dr. Fixit MPB — Multi-Purpose Polymer Bonding Agent for Concrete \u0026 Plaster","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMost repair jobs on site fail not because the repair mortar was wrong — but because nothing was done to prepare the surface to actually receive it. Old concrete is smooth, carbonated, and doesn't want to bond with new material. Apply a repair mortar directly onto an unprepared surface and you've essentially stuck new concrete on top of old concrete with nothing holding them together — and within a season, that repair is cracking, delaminating, or falling off entirely. Dr. Fixit MPB is the polymer \u003cstrong\u003ebonding agent\u003c\/strong\u003e that fixes this problem before it starts — and it's what experienced \u003cstrong\u003ewaterproofing contractors\u003c\/strong\u003e and repair applicators reach for when they want their \u003cstrong\u003econcrete crack repair\u003c\/strong\u003e to actually last.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMPB is a multi-purpose polymer bonding agent that does two jobs depending on how you use it. Applied as a slurry coat onto the prepared substrate before plastering or repair mortar application, it creates a chemically active bonding bridge between the old surface and the new material — dramatically improving adhesion and eliminating the delamination that happens without it. Used as an additive mixed directly into cement mortars, plaster, or \u003cstrong\u003ecementitious waterproofing\u003c\/strong\u003e slurries, it improves the flexibility, workability, and long-term durability of the mix itself. Both applications, one product.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIt works across a wide range of \u003cstrong\u003econstruction chemical\u003c\/strong\u003e repair and surface preparation scenarios — bonding new plaster to old concrete walls, improving the bond of repair mortars on \u003cstrong\u003ewall crack repair\u003c\/strong\u003e applications, enhancing adhesion for floor screeds and toppings, and improving the performance of polymer-modified waterproofing coatings. Anywhere old and new concrete or mortar meet, MPB is the \u003cstrong\u003econstruction chemical\u003c\/strong\u003e that makes the connection permanent instead of temporary.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eStraightforward to use, genuinely versatile, and backed by Dr. Fixit's trusted waterproofing and repair expertise — MPB is the product that makes every other repair product in your system perform better.\u003c\/p\u003e","brand":"Dr. Fixit Waterproofing Solution","offers":[{"title":"Default Title","offer_id":43063404888123,"sku":null,"price":13752.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/8427\/0395\/files\/ChatGPTImageMay26_2026_10_23_22AM.png?v=1779772383","url":"https:\/\/adtindustries.com\/products\/dr-fixit-mpb","provider":"ADT INDUSTRIES PRIVATE LIMITED - WATERPROOFING SOLUTIONS IN INDIA","version":"1.0","type":"link"}
