Key Features

  1. Superior Elasticity & Adhesion – Rubber-like flexibility with strong tensile and crack resistance.
  2. Excellent Durability – Waterproof, anti-aging, and weather-resistant for long-term protection.
  3. Direct Exposure Finish – Can be used as a decorative surface when fully cured; available in multiple colors.
  4. Eco-Friendly Formula – Low VOC content and safe for indoor and outdoor use.


Application Method

  1. Surface Preparation
    Ensure the substrate is clean, firm, and free from dust, oil, or moisture.
  2. Base Treatment
    Fill gaps or cracks and reinforce weak areas with primer or additional coating.
  3. Coating Application
    Apply the liquid rubber coating evenly in multiple thin layers. Allow each layer to dry before applying the next to achieve the desired film thickness.


Precautions

  • Avoid applying too thick in a single coat; use multiple thin layers for optimal waterproof performance.
  • If bubbles appear due to humidity or uneven coating, wait until dry, then reapply after removing bubbles.
  • Do not expose the coated surface to water or rain within 48 hours after application.
