What are the key features and advantages of BOSLAI Transparent Waterproof Coating?
BOSLAI transparent waterproof coating — a premium invisible waterproof sealant — offers 5 core advantages that make it versatile for both indoor and outdoor applications:
- UV Resistance: Withstands long-term sunlight exposure without degradation or peeling, making it ideal for outdoor walls, roofs, and facades in any climate.
- Weather Resistance: Resistant to oxidation, ozone, acid, alkali, and moisture erosion. Maintains waterproofing effectiveness even in harsh climates and extreme temperatures.
- High Elasticity: The coating film has excellent elasticity (elongation at break ≥316%), adapting to minor substrate deformations and resisting cracking caused by thermal expansion and contraction.
- Excellent Waterproof Ability: Effectively prevents water penetration, providing reliable waterproofing with impermeability tested at 0.3 MPa for 30 minutes. Blocks efflorescence and stops water seepage at the source.
- Strong Adhesion & High Transparency: Bonds strongly to wall tiles, stone, concrete, and masonry surfaces. Does not peel off in continuous rain, resists yellowing, repels dust, and maintains high clarity — preserving the original appearance of decorative surfaces.
Why choose a clear waterproof coating? Unlike pigmented coatings, a transparent waterproof paint preserves the original color and texture of tiles, marble, and decorative walls. This makes it the preferred choice for renovation projects, heritage buildings, and any surface where visual appearance must be maintained.

FAQ
Q1: Can BOSLAI transparent waterproof coating be applied over existing tiles without removing them?
Yes. BOSLAI transparent waterproof coating is designed for direct application over existing wall tiles, ceramic tiles, marble, granite, and real stone paint surfaces — no demolition required. The clear liquid forms an invisible waterproof membrane that bonds to the tile surface without altering its appearance. This makes it ideal for bathroom and balcony renovations where removing tiles would be costly and disruptive.
Q2: Is this transparent waterproof coating suitable for outdoor use?
Yes. BOSLAI clear waterproof coating is UV-resistant and weather-resistant, making it suitable for exterior walls, roofs, terraces, balconies, and facades. It withstands long-term sunlight exposure without yellowing, peeling, or degrading. The coating remains flexible from -10°C to high summer temperatures, accommodating thermal expansion and contraction on outdoor surfaces.
Q3: How many coats are required, and what is the coverage rate?
Two coats are recommended for standard waterproofing applications. Each kilogram covers approximately 3 m² per coat, so a 20kg pail covers roughly 60 m² per coat. For high-stress areas such as basements or areas with continuous water exposure, a third coat may be applied. Allow the first coat to become tacky (not fully dry) before applying the second coat for optimal interlayer adhesion.
Q4: What surfaces does BOSLAI transparent waterproof coating adhere to?
BOSLAI clear waterproof sealant bonds strongly to a wide range of substrates, including: concrete, cement mortar, wall tiles, ceramic tiles, marble, granite, stone, real stone paint, exterior decorative coatings, wood surfaces, and window sill cement surfaces. No primer is required on most standard substrates.
Q5: Is BOSLAI transparent waterproof coating eco-friendly and safe for indoor use?
Yes. BOSLAI transparent waterproof coating is a water-based, green, environmentally friendly product. It is non-toxic, non-flammable, and non-explosive. It contains no harmful solvents and is safe for application in bathrooms, kitchens, and enclosed indoor spaces. Workers can apply it using standard brushes or rollers without special respiratory protection.
Q6: What is the difference between transparent waterproof coating and traditional pigmented waterproof coating?
The main difference is appearance. A transparent waterproof coating dries completely clear, preserving the original look of tiles, marble, and decorative surfaces. Traditional pigmented coatings cover the surface with a colored film. Transparent coating is preferred for renovation projects, tile surfaces, and decorative walls where aesthetics must be maintained. Additionally, BOSLAI’s formula offers UV resistance, high elasticity (316% elongation), and strong adhesion — performance comparable to pigmented coatings but with the added benefit of invisibility.
Q7: How to find a reliable transparent waterproof coating manufacturer and exporter in China?
When sourcing transparent waterproof coating China, evaluate suppliers on these five key points:
- TDS & Specifications — A reliable transparent waterproof coating manufacturer should provide complete technical data sheets before you order, not after.
- Specialization — A dedicated waterproofing manufacturer has better formulation expertise than a general chemical trader.
- Samples — Always test on your actual substrate before committing to bulk orders.
- OEM Capability — Custom packaging, labeling, and formulation adjustments if you are building your own brand.
- Export Compliance — MSDS, DG classification, and customs documentation for smooth international shipping. A qualified transparent waterproof coating exporter should handle all export paperwork.
At BOSLAI, we provide downloadable TDS and product specifications, support sample shipping and OEM customization, and have export experience across 40+ countries — so you can verify quality firsthand through samples before placing a bulk order.
Q8: What should I know about transparent waterproof coating import from China?
For transparent waterproof coating import buyers, here are the key steps and considerations:
- Product Classification: Transparent waterproof coating is classified as a water-based chemical product (non-hazardous in most jurisdictions). Confirm HS codes and import regulations with your customs broker.
- Documentation: Request TDS, MSDS, and certificate of origin from your transparent waterproof coating China supplier. BOSLAI provides all export documents.
- Shipping Terms: BOSLAI offers FOB (Shanghai/Ningbo) and CIF pricing. For first-time orders, FOB is recommended so you can control freight. For regular orders, CIF may be more convenient.
- MOQ: Minimum order quantity is typically 1,000 kg for standard packaging. OEM/private-label orders may require higher MOQ.
- Lead Time: Production takes 7–15 days for standard orders; OEM orders may take 15–25 days depending on packaging customization.
- Sample Testing: BOSLAI provides free samples (you pay freight only) so you can test the transparent waterproof coating on your local substrates before committing to a full order.
Q9: What are the application methods and construction precautions for transparent waterproof coating?
BOSLAI transparent waterproof coating is designed for easy application:
- Apply by brush, roller — standard tools are sufficient, no special equipment needed.
- Recommended film thickness: 1.5mm–2mm across two coats.
- Construction temperature: 5°C–35°C. Do not apply on windy or rainy days.
- The base surface must be clean, dry, and free of standing water, oil stains, and dust before application.
- For cracked or perforated areas, first fill with waterproof glue mixed with talcum powder, putty powder, or cement to create a paste for leveling.
- Apply the second coat before the first coat is completely dry for optimal interlayer bonding.
- After construction, protect the waterproof layer from sharp objects until fully cured.
