Exterior Wall Transparent Waterproof Sealant

High Transparency & Invisible Aesthetics: After curing, the coating is completely transparent and does not alter the original color or texture of the wall—perfect for various finishes.

Outstanding Waterproofing & Long-Lasting Protection: Extremely low water absorption; excellent resistance to water intrusion; able to withstand rain for long periods without moisture penetration.

High Elasticity & Crack Resistance: The coating has excellent elongation; can cover micro-cracks (<0.5 mm), and expands/contracts with substrate without cracking.

Weather-Resistant & Durable Aging Performance: Added UV stabilizers; resistant to heat and cold, acid and alkali; suitable for harsh climates with long service life.

Good Breathability & Mold / Moisture Resistance: While waterproof, allows slight vapor transmission from inside substrate, preventing blistering or mold behind finishes.

Eco-Friendly & Easy Application: Water-based, non-toxic, odorless; meets environmental standards. Ready to use; can be applied by brush, roller or spray—saves time and effort.

Wall Types: Cement-sand plaster surfaces, concrete, brick walls, natural stone curtain walls, decorative stone, real stone paints, tile grout joints, etc.

Use Cases:
  • Waterproofing and seepage protection for exterior walls, balconies, terraces.
  • Full external wall maintenance for villas, self-built houses, residential complexes.
  • Reinforcement at water-prone areas: around windows, AC units, baseboard edges.
  • Renovation of old walls—no need to strip original finishes; direct application.

Surface Preparation
  • Cleaning: Remove dust, oil, algae, loose particles; ensure substrate is sound, flat, clean.
  • Repair: Fill visible cracks or holes > 0.5 mm with cement mortar or leak sealant; ensure smoothness.
  • Drying: Substrate must be thoroughly dry.

Application Method
  • Stirring: Gentle mixing once opened; no dilution with water.
  • Coating: Use roller, brush, or spray. Apply at least two coats; the directions should be perpendicular (first coat horizontal, second vertical).
  • Drying between coats: First coat becomes surface-dry in about 2-4 hours (depending on weather) before applying the second.
  • Coverage: Approximately 0.3-0.4 kg/m² per coat (actual use depends on substrate roughness).

Curing / Maintenance
  After completion, allow natural curing for 24-48 hours until film is fully hardened. Avoid exposure to rain or mechanical damage during this period.

Non-flammable and non-explosive; can be transported as general goods. During transport, protect from rain, direct sunlight, freezing, and package damage.

Store in a dry, cool place (5 °C - 35 °C), avoid exposure to sunlight or rain. Relative humidity ≥ 85% requires moisture protection. Under normal conditions of transport and storage, shelf life is usually 6 to 12 months.

Working environment: Avoid applying during rainy or foggy weather, or at temperatures below 5 °C or above 40 °C. If rain occurs within 6 hours after application, protective measures should be taken.

Personal protection: Wear gloves, safety goggles, etc. In case of contact with eyes, rinse with plenty of water immediately and seek medical advice.
