<\/p>\nJY-TOS Organic Silicone Rubber Waterproof Coating is a single-component, water-based material that uses organic silicone rubber lotion as its main film-forming component. It is primarily applied for waterproofing and anti-seepage protection on roofs, basements, swimming pools, bridges, and various concrete structures, with a typical service life of up to 20 years.<\/p>\n
The coating penetrates approximately 0.3 mm into the concrete matrix to create a dense waterproof layer. It maintains performance across a wide temperature range from \u201320 \u00b0C to 100 \u00b0C, offers high elasticity, good adhesion, and remains breathable while blocking liquid water. The material resists UV aging, is non-toxic, low-VOC, and meets environmental requirements. It is available in several colors to suit basic decorative needs.<\/p>\n
Application is straightforward using brush, roller, or spray on clean concrete or masonry surfaces. The coating cures at room temperature and requires no special heating or priming in most situations.<\/p>\n

The coating went on without issues, no strong smell, and dried quickly even in the heat. After one year and two rainy seasons, no leaks reported so far. The light grey color helped reduce surface temperature a little. Solid performance for the price.<\/p>\n Maria Costa \u2013 Lisbon, Portugal (Homeowner)<\/strong> Applied two coats myself on an old 1970s concrete balcony that always leaked into the bedroom. Surface was cleaned and slightly damp \u2013 the material still stuck well. It has been 14 months including a very wet winter, and the balcony stays dry. The finish is matte and does not look shiny or plastic, which I prefer.<\/p>\n Tan Wei Jie \u2013 Singapore (Renovation company)<\/strong> We specify JY-TOS for basement car park walls and swimming pool surround areas. The penetration into concrete is noticeable and the film stays elastic after curing. Crew likes that it\u2019s single-component and low odor \u2013 important when working in occupied buildings. So far all projects passed the 24-hour water ponding test without problems.<\/p>\n John Davies \u2013 Manchester, UK (Building surveyor)<\/strong> Recommended this organic silicone rubber waterproof coating for a 1990s housing block with persistent roof seepage. Contractor applied three coats over the existing asphalt. Inspection 18 months later showed the coating still intact, no blistering even after a typical wet British winter. Good breathability seems to prevent moisture trapped underneath.<\/p>\n Carlos Ram\u00edrez \u2013 Bogot\u00e1, Colombia (Civil engineer)<\/strong> Used it on an exposed pedestrian bridge walkway. The surface freezes occasionally at night (around \u20132 \u00b0C) and gets direct sun during the day. After two years the waterproof layer is still flexible and no cracks appeared at the movement joints. Color has faded slightly but protection remains effective.<\/p>\n Q1: Is JY-TOS suitable for direct contact with drinking water?<\/strong> No, it is designed for general construction waterproofing (roofs, basements, pools, etc.). It is non-toxic after full cure, but it is not certified for potable water tanks.<\/p>\n Q2: Can it be applied on a damp surface?<\/strong> Yes, it can tolerate slightly damp (not wet) concrete. Standing water must be removed and the surface should be free of loose particles.<\/p>\n Q3: Does it require a primer?<\/strong> In most cases on clean concrete or cementitious substrates, no primer is needed. On very smooth or dusty surfaces, a diluted coat of JY-TOS itself (1:1 with water) can be used as a primer.<\/p>\n Q4: What is the recommended thickness\/dosage?<\/strong> Typical total consumption is 1.6\u20132.2 kg\/m\u00b2 for 1.0\u20131.2 mm dry film thickness (usually 2\u20133 coats). Higher dosage (2.5\u20133.0 kg\/m\u00b2) is advised for exposed roofs or water-retaining structures.<\/p>\n Q5: Can it be used on metal roofs?<\/strong> Yes, but the metal surface must be clean, rust-free, and stable. A suitable anti-corrosion primer is recommended before applying JY-TOS.<\/p>\n Q6: How long does it take to cure?<\/strong> Touch-dry in 2\u20134 hours, recoatable after 4\u20138 hours (depending on temperature and humidity). Full cure and maximum water resistance is reached after 5\u20137 days.<\/p>\n Q7: Will the color fade under sunlight?<\/strong> Light colors (grey, beige) show minimal fading. Darker colors may fade slightly over 2\u20133 years but waterproofing performance is not affected.<\/p>\n Q8: Can it be walked on after application (e.g., rooftop)?<\/strong> Yes, after full cure it can withstand foot traffic. For regular maintenance traffic, a protective cement-sand screed or walking pads are recommended.<\/p>\n Q9: What is the shelf life?<\/strong> 24 months from production date if stored in original sealed pails in a cool, dry place (5\u201335 \u00b0C).<\/p>\n Q10: Can it bridge cracks?<\/strong> It can bridge static hairline cracks up to approx. 0.4 mm. For moving cracks or joints wider than 1 mm, additional reinforcement (polyester fabric + extra coats) is required.<\/p>\n<\/div>\n Great Ocean Waterproof Technology Co., Ltd.
