        APPLICATION<\/span><\/h4>\n

        WINDRAIN ULTRA is mixed with natural aggregates of various colours and sizes to produce seamless, decorative and free-draining resin-bound paving systems.<\/p>\n

        The mixture can be installed on properly prepared substrates using standard resin-bound paving techniques.<\/p>\n

        INSTALLATION RECOMMENDATIONS<\/h4>\n

        For optimum performance:<\/p>\n

          \n
        • ensure the substrate is sound, clean, dry and free from contaminants;<\/li>\n
        • do not apply when substrate temperatures are below 0\u00b0C (32\u00b0F);<\/li>\n
        • low temperatures significantly slow the curing process;<\/li>\n
        • high temperatures reduce the working time;<\/li>\n
        • mix only the quantity that can be installed within the product’s pot life.<\/li>\n<\/ul>\n
          \n

          COVERAGE<\/span><\/h4>\n
            \n
          • Recommended dosage: 5% by weight of aggregates<\/strong>.<\/li>\n
          • Recommended compacted thickness: \u2265 30 mm<\/strong>.<\/li>\n<\/ul>\n
            \n

            STORAGE<\/span><\/h4>\n

            Store in the original unopened packaging for up to 12 months<\/strong> in a clean and dry environment.<\/p>\n

            Protect from frost. Recommended storage temperature: +5\u00b0C to +35\u00b0C (41\u00b0F\u201395\u00b0F)<\/strong>.<\/p>\n

            \n
