Product Features<\/h2>\n
\n
Boasts unique waterproof performance, high elasticity and overall integrity\u2014its coating is seamless and continuous for full-coverage protection.<\/div>\n
Example<\/strong>: If your roof has tiny cracks or uneven surfaces, this seamless coating will adhere to every detail (no gaps like traditional waterproof rolls). Its high elasticity also stretches with the roof\u2019s expansion\/contraction (e.g., from 35\u2103 daytime heat to 10\u2103 nighttime cool) to avoid new cracks that cause rain leaks.<\/div>\n<\/blockquote>\n

Delivers strong high-temperature resistance, low-temperature tolerance, and reliable aging resistance.
\nExample<\/strong>: In southern China\u2019s summer, where roof surfaces hit 60\u2103+, this coating won\u2019t soften\/melt. In northern China\u2019s -20\u2103 winter, it won\u2019t turn brittle\/crack. After 5+ years of outdoor exposure, it still blocks water (unlike cheap coatings that peel after 1 year).<\/p>\n

Offers good elongation performance paired with excellent UV resistance.<\/div>\n
Example<\/strong>: For exterior walls exposed to 8+ hours of daily sunlight, its high elongation follows minor wall movements (e.g., from foundation settling) without tearing. Its UV resistance also prevents fading\/cracking\u2014no need to re-coat for 4+ years (saving maintenance costs).<\/div>\n
<\/div>\n
Is a single-component, water-soluble formula that can be easily applied via rolling or spraying.<\/div>\n
Example<\/strong>: On a 100\u33a1 basement project, workers skip mixing multiple materials (saving 30 mins of prep). They use a roller for pipe corners or a sprayer for large floors\u2014cutting application time by ~25% vs. multi-component coatings.<\/div>\n
<\/div>\n
Features green, environmentally friendly properties; it enables simple construction and helps shorten the overall construction period.<\/div>\n
Example<\/strong>: When waterproofing an indoor garage, this low-odor coating needs no extra ventilation (safe for on-site teams). Its fast-drying nature lets you lay floor tiles 24 hours later\u2014trimming the waterproofing phase from 3 days to 1 day.<\/div>\n

Construction Method<\/h2>\n
    \n
  1. Base Cleaning<\/strong>: Prior to liquid roll waterproofing construction, thoroughly clean the base surface to remove dust, debris, or other contaminants.<\/li>\n
  2. Base Layer Humidity Check<\/strong>: Ensure the base surface is dry, with its moisture content controlled below 8% (as a general requirement).<\/li>\n
  3. Material & Tool Preparation<\/strong>: Prepare the liquid roll coating and matching construction tools, including brushes, rollers, scrapers, and spray guns.<\/li>\n
  4. Primer Application<\/strong>: Evenly apply primer to the base surface (no missed areas), with a base coating thickness of 0.2\u20130.3mm. Wait for the primer surface to dry completely before proceeding.<\/li>\n
  5. First Liquid Roll Coating<\/strong>: Use a brush, roller, or spray gun to apply the first coat of liquid roll. Maintain uniform coverage during application, avoiding issues like missed brushing, bubbles, or material accumulation. Allow the surface to dry (typically 1\u20132 hours).<\/li>\n
  6. Multi-Pass Brushing<\/strong>: It is recommended to apply 2\u20133 coats total. Wait for the previous coat to fully dry before applying the next one; apply each coat in vertically intersecting directions to ensure even coverage.<\/li>\n
  7. Joint Treatment<\/strong>: Joints and nodes (key waterproofing areas) should be reinforced with reinforced cloth or liquid roll-specific waterproof tape, then apply the liquid roll coating over the reinforced area.<\/li>\n<\/ol>\n

            FAQ<\/h2>\n
            \n

            What factors should I consider when choosing between bituminous membranes, coatings (like JY-LRT), or paints for my waterproofing project?<\/h3>\n
              \n
            • When selecting bituminous waterproofing solutions, align the option with your project\u2019s specifics\u2014here\u2019s how JY-LRT fits in:<\/li>\n
            • Type of Structure<\/strong>: Membranes work best for large, flat industrial roofs, while JY-LRT (a liquid waterproof roll coating) suits both large spaces (basements, garages) and detailed areas (kitchen\/bathroom pipe joints) thanks to its seamless, adaptable application.<\/li>\n
            • Weather Exposure<\/strong>: JY-LRT handles harsh conditions (60\u2103+ heat, -20\u2103 cold) and UV exposure, making it ideal for outdoor roofs\u00a0and<\/em>\u00a0indoor spaces. Membranes offer similar resilience but with higher upfront costs.<\/li>\n
            • Ease of Application<\/strong>: Membranes require professional installation, but JY-LRT (single-component, water-soluble) can be applied via brush\/roller\/spray\u2014saving time for mid-sized projects.<\/li>\n
            • Cost Considerations<\/strong>: JY-LRT is a cost-effective pick for small (bathrooms) and medium (garages) jobs, with 5+ years of outdoor performance (vs. pricier membranes for large-scale industrial use).<\/li>\n<\/ul>\n

              How does JY-LRT perform in extreme weather (freezing temperatures or intense sunlight)?<\/h3>\n
                \n
              • JY-LRT is built for tough climates:<\/li>\n
              • Freezing Temperatures<\/strong>: Its high elasticity stays flexible through -20\u2103 winter freeze-thaw cycles (common in northern regions), avoiding brittleness or cracking that causes leaks.<\/li>\n
              • Intense Sunlight\/Heat<\/strong>: It resists softening\/melting on 60\u2103+ summer roof surfaces, and its UV resistance prevents fading\/cracking from prolonged sun exposure.<\/li>\n
              • This resilience makes it reliable for outdoor structures (roofs) and semi-outdoor areas (patios) year-round.<\/li>\n<\/ul>\n

                What maintenance practices maximize JY-LRT\u2019s durability?<\/h3>\n
                  \n
                • To extend JY-LRT\u2019s service life (5+ years outdoors, longer indoors):<\/li>\n
                • Routine Inspections<\/strong>: Check 1\u20132 times yearly (especially joints\/nodes) for cracks\/blisters\u2014prioritize checks after heavy rain or extreme temperature swings.<\/li>\n
                • Debris\/Water Removal<\/strong>: Clear leaves\/dirt\/standing water from surfaces (roofs, garages) regularly; unclog gutters to avoid water buildup that speeds up material breakdown.<\/li>\n
                • Prompt Repairs<\/strong>: Seal small cracks immediately with a thin JY-LRT coat (after cleaning) to prevent larger leaks.<\/li>\n<\/ul>\n

                  How soon can I start subsequent work (e.g., laying tiles) after applying JY-LRT?<\/h3>\n
                    \n
                  • Under standard conditions (25\u2103, 50% RH), the final JY-LRT coat dries completely in ~24 hours. You can safely lay tiles or proceed with other construction after this full-drying period (adjust timelines for more humid\/hotter environments).<\/li>\n<\/ul>\n

                    Can JY-LRT be applied on damp substrates, and what\u2019s the moisture limit?<\/h3>\n
                      \n
                    • Yes\u2014JY-LRT works on moderately damp substrates (great for basements). However, the base layer\u2019s moisture content must stay below 8% (per construction guidelines) to ensure strong adhesion and long-term performance.<\/li>\n<\/ul>\n

                      How do I get a price quote for JY-LRT?<\/h3>\n
                        \n
