Category:
PRODUCT NAME: PC-Sealcoat® 220

Generic Type: Premium Hybrid Polyurethane Waterproofing Membrane

PRODUCT DESCRIPTION

PC-Sealcoat® 220 is a premium, single-component, hybrid polyurethane-based liquid applied waterproofing membrane. Engineered for high-performance protection, it is designed to coat roofs, terraces, balconies, wet areas, and exposed surfaces.

Upon curing, it forms a tough, seamless, and highly flexible membrane that offers excellent crack-bridging capabilities. Its unique formulation ensures strong adhesion to various substrates—including concrete, screed, metal, and existing tiles—while providing exceptional resistance to weathering and UV radiation.

1. AREAS OF APPLICATION

  • Exposed Roofs: Flat and sloped concrete roofs.

  • Outdoor Living: Terraces, balconies, and podiums.

  • Wet Areas: Bathrooms, kitchens, and laundry areas (under tile).

  • Refurbishment: Over existing old tiles or metal roofing sheets.

  • Masonry & Walls: Exterior walls and parapets.

2. KEY FEATURES & BENEFITS

Performance & Durability

  • Hybrid Polyurethane Technology: Combines the durability of PU with the ease of acrylics to provide superior flexibility and mechanical strength.

  • 100% Seamless: Creates a monolithic membrane that eliminates joints, seams, and weak points where leaks commonly occur.

  • UV-Resistant & Color Stable: Specifically designed for exposed surfaces; it will not yellow, chalk, or degrade under direct sunlight.

  • High Crack-Bridging: Highly elastic properties allow the membrane to accommodate thermal expansion/contraction and bridge hairline cracks in the substrate.

Versatility & Protection
  • Dual Pressure Resistance: Unique formulation suitable for resisting both Positive and Negative water pressure.

  • Solar Reflective: (White/Light colors) Reduces heat absorption, lowering surface temperatures and building cooling costs.

  • Universal Adhesion: Bonds excellently to concrete, cement screed, glazed tiles, wood, metal, and masonry without the need for aggressive mechanical roughening.

Application & Safety

  • User-Friendly Application: Single component system applied easily via brush, roller, or airless spray.

  • Fast Curing: Quick drying time allows for faster project completion and weather resistance.

  • Eco-Friendly: Low-VOC (Volatile Organic Compounds) formulation makes it safe for applicators and the environment.

4. TECHNICAL HIGHLIGHTS

  • Chemical Base: Hybrid Polyurethane-Acrylic

  • Finish: Smooth / Matt (Solar Reflective)

  • Elongation: High flexibility

  • Water Permeability: Impermeable

5. GENERAL APPLICATION GUIDE

  1. Surface Preparation: Ensure the surface is clean, dry, and free of dust, oil, grease, or loose particles. Repair structural cracks before application.

  2. Priming: (Optional/As per specific tech sheet) Apply a primer if the surface is highly porous.

  3. First Coat: Apply PC-Sealcoat® 220 evenly using a roller or airless spray.

  4. Reinforcement: (If required) Embed a geotextile fabric into the wet first coat for critical areas (corners, joints).

  5. Second Coat: Apply the second coat cross-wise to the first coat once the first is dry to touch.
