Waterproofing Color Steel Roof Tiles with Polyaspartic Polyurea


Many buildings, for aesthetic appeal, adorn their rooftops with color steel, particularly on steep roofs of villas or factories. Although color steel sheets are processed with various paints for durability and water resistance, weather-induced damage such as rusting, expansion, and contraction can lead to leaks. Color steel rooftops have their pros and cons. A well-structured color steel roof rarely leaks, and if it does, the affected parts can be easily replaced or temporarily welded. However, extensive corrosion or aging-related leaks can be problematic, with high waterproofing costs. Therefore, early-stage waterproofing is crucial.


1. Assessing the Need for Waterproofing on Color Steel Roofs To maintain a color steel roof, don't wait for leaks to start thinking about waterproofing. Here's how to assess if maintenance or waterproofing is required:

  • Color Changes: If the coating on the rooftop color steel appears powdered, faded, or discolored, it's time for maintenance or waterproofing.
  • Rust Spots: Rust spots, often due to paint peeling or poor drainage, are early signs of leaks and should be addressed immediately.


Knowing how to assess the condition of your color steel roof is pivotal in choosing the right waterproofing material.

2. Drawbacks of Current Waterproofing Materials for Color Steel Tile Roofs

  • Traditional Sealants: Prone to aging and temperature effects. Sealants shrink upon setting, causing detachment from the frame, and prolonged exposure accelerates aging, leading to loss of effectiveness.
  • Traditional Waterproof Coatings: Low elongation rates can result in cracks due to roof vibrations, and traditional coatings tend to age and crack when exposed to the elements.


The innovative solution of Polyaspartic Polyurea waterproof coating addresses these issues:

  • Local Seam Coating: Applying Polyaspartic Polyurea over a 15-20cm area along the seams seals gaps between tiles. Its elastic properties prevent cracking from thermal expansion, thus effectively preventing leaks.
  • Full Roof Coverage: A comprehensive coating plan based on the specific project prevents paint degradation due to exposure and extends the life of the color steel tiles by over 20 years, reducing the need for frequent replacements and saving costs.


3. Benefits of Polyaspartic Polyurea Waterproof Coating:

  1. Long-term outdoor protection against sunlight.
  2. Excellent adhesion to metal substrates, preventing peeling, cracking, and leaks.
  3. Overcomes the 'low strength' issue of traditional coatings, providing a high elasticity, high strength film to prevent leaks due to deformation of color steel tiles.
  4. Unaffected by -35 degrees weather, solving the problem of winter cracking without the need for frequent repairs.
  5. Integrates waterproofing and aesthetics with a variety of colors for decorative purposes.
  6. Overcomes the fast gel time and the need for specialized equipment typically associated with traditional polyurea.


Polyaspartic Polyurea's advantages are not limited to waterproofing; it also excels in anti-corrosion and flooring projects.
