P-301 Multipurpose Hybrid Primer

301 Multipurpose Hybrid Primer is a high-solids, all-purpose roof primer designed to promote adhesion, block asphalt bleed-through, and improve coating performance. It bonds tightly to TPO, PVC, and metal, and builds meaningful mils for smoothing cracks and sealing rust. Use under silicone or acrylic systems to simplify application and increase resistance to ponding water. Not for use with EPDM.

• 51% solids by volume: Builds mils and smooths uneven surfaces
  
  
• Excellent adhesion to TPO, PVC, and metal
  
  
• Blocks asphalt oils from bleed-through in silicone systems
  
  
• Enhances ponding water resistance in acrylic systems
  
  
• Encapsulates surface rust and fills micro-cracks
