JY-TOS Organic Silicone Rubber Waterproof Coating

Instant Adhesive Powder For Construction

The production process uses a positive pressure feeding system and automated mixing equipment to ensure particle uniformity and stable product quality through precise control of the ratio of main and auxiliary materials. The primary physical properties include high bonding strength, weather resistance, and crack resistance, enabling full integration with cement-based materials to form a high-strength bonding layer.

• Physical properties: toughness reaches 3.2 MPa; weather resistance test passes 2000 hours of UV irradiation
• Dissolution characteristics: completely dissolves in cold water within 3 minutes, forming a colloid with viscosity of 8000 CPS
• Adhesive strength: after mixing with cement, bonding strength is significantly increased; suitable for environments from -20 °C to 80 °C
• Stability: the colloid remains stable for 72 hours without stratification; pH value is maintained between 8.5–9.5

Müşteri Yorumları

Ahmed Al-Mansoori – Dubai, UAE (Rooftop contractor) We used JY-TOS on several flat concrete roofs last summer when temperatures were above 45 °C. 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.

Maria Costa – Lisbon, Portugal (Homeowner) Applied two coats myself on an old 1970s concrete balcony that always leaked into the bedroom. Surface was cleaned and slightly damp – 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.

Tan Wei Jie – Singapore (Renovation company) 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’s single-component and low odor – important when working in occupied buildings. So far all projects passed the 24-hour water ponding test without problems.

John Davies – Manchester, UK (Building surveyor) 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.

Carlos Ramírez – Bogotá, Colombia (Civil engineer) Used it on an exposed pedestrian bridge walkway. The surface freezes occasionally at night (around –2 °C) 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.

FAQ

Q1: Is JY-TOS suitable for direct contact with drinking water? 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.

Q2: Can it be applied on a damp surface? Yes, it can tolerate slightly damp (not wet) concrete. Standing water must be removed and the surface should be free of loose particles.

Q3: Does it require a primer? 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.

Q4: What is the recommended thickness/dosage? Typical total consumption is 1.6–2.2 kg/m² for 1.0–1.2 mm dry film thickness (usually 2–3 coats). Higher dosage (2.5–3.0 kg/m²) is advised for exposed roofs or water-retaining structures.

Q5: Can it be used on metal roofs? Yes, but the metal surface must be clean, rust-free, and stable. A suitable anti-corrosion primer is recommended before applying JY-TOS.

Q6: How long does it take to cure? Touch-dry in 2–4 hours, recoatable after 4–8 hours (depending on temperature and humidity). Full cure and maximum water resistance is reached after 5–7 days.

Q7: Will the color fade under sunlight? Light colors (grey, beige) show minimal fading. Darker colors may fade slightly over 2–3 years but waterproofing performance is not affected.

Q8: Can it be walked on after application (e.g., rooftop)? Yes, after full cure it can withstand foot traffic. For regular maintenance traffic, a protective cement-sand screed or walking pads are recommended.

Q9: What is the shelf life? 24 months from production date if stored in original sealed pails in a cool, dry place (5–35 °C).

Q10: Can it bridge cracks? 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.
