PC-Sealcoat® Top

UV-resistant top coat to surfaces exposed to sun light to achieve a glossy, color-stable finish that resists chalking.

PC-Sealcoat® Top is a pigmented, colorfast, and UV-stable coating known for its exceptional durability and elasticity. Applied and cured at low temperatures, this single-component aliphatic polyurethane coating is tailored to serve as a protective top layer over exposed polyurethane waterproofing coatings. Through a moisture-induced chemical reaction with ambient moisture, this coating provides enduring safeguarding properties.

FEATURES AND BENEFITS

  • Application is simplified through the use of a roller or airless spray method.
  • Formulated as a single component.
  • Improves the abrasion and wear resistance of the underlying waterproofing membrane.
  • Exhibits high sun reflectivity, offering thermal insulation advantages.
  • Demonstrates UV and color stability, ensuring enduring performance.
  • Yields a lustrous surface that is easy to clean.
  • Resistant to the chalking effect commonly observed in aromatic polyurethane coatings.
  • Endures water, heat, and frost exposure.
  • Maintains mechanical properties within a temperature range from -40°C to +90°C.
  • Suitable for pedestrian traffic on waterproofed surfaces in residential environments.

METHOD OF APPLICATION

Surface preparation

  • Careful surface preparation is essential for optimum finish and durability.
  • The surface needs to be clean and sound, free of any contamination, which may harmfully affect the adhesion of the primer.
  • Maximum moisture content should not exceed 5%. Substrate compressive strength should be at least 25 MPa (N/mm²), cohesive bond strength at least 1.5 MPa (N/mm²). Old coatings, dirt, organic substances and dust need to be removed by a grinding machine.
  • Oil or grease contamination must be cleaned substantially. Possible surface irregularities need to be smoothened. Any loose surface particles and grinding dust need to be thoroughly removed.

WARNING: Do not wash the surface with water!
