They are small molecules that when applied onto a substrate penetrate deep below the surface. They chemically react with cementitious substrates to form a cross-linked silicate polymer that permanently blocks substrate capillaries reducing the movement of water. The substrate becomes significantly denser, harder and stronger and is less susceptible to dusting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey advantages\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSignificantly increases density, hardness and strength\u003c\/p\u003e\n\u003cp\u003eExcellent dust proofing of substrates\u003c\/p\u003e\n\u003cp\u003eSignificantly reduces movement of water\u003c\/p\u003e\n\u003cp\u003eMinimises efflorescence\u003c\/p\u003e\n\u003cp\u003eHigh penetration into masonry surfaces\u003c\/p\u003e\n\u003cp\u003eHigh wear resistance, UV stable, long life\u003c\/p\u003e\n\u003cp\u003eCan be applied to damp or wet substrates\u003c\/p\u003e","brand":"sifsealers","offers":[{"title":"20L","offer_id":46481180360893,"sku":"SiDS-20C","price":469.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/2241\/5549\/files\/5and20LSi20DS_b4ecc24c-9f44-46dd-a734-66fa773d3090.jpg?v=1772937836","url":"https:\/\/sifsealers.co.nz\/products\/si20-ds-water-based-sealer-and-densifier-ready-to-use","provider":"SiF Sealers NZ","version":"1.0","type":"link"}
