PC-Plast® AP 34

Torch applied waterproofing membrane

The PC-Plast® AP 34 APP-modified bitumen membrane is meticulously designed for the foundational layer within a dual-layer roofing system, catering to a diverse range of buildings and structures. Its primary function is to provide waterproofing for foundations and engineering structures, serving as an ideal substrate for bitumen shingles on pitched roofs in both new construction and renovation projects. This material exhibits exceptional resilience to temperature fluctuations and significant mechanical stress, ensuring long-lasting, reliable, and effective waterproofing. The incorporation of APP polymer enhances its resistance to deformation, making it particularly suitable for use in warmer climates. Additionally, the underside is safeguarded by a polymer film featuring distinct graphic elements that melt upon reaching the appropriate temperature during application, while the top surface is similarly protected by a polymer film.

GENERAL REQUIREMENTS

  • Ensure that rolls of the material are stored indoors in a dry environment, maintaining them in their original packaging until transportation to the construction site is necessary.
  • Store the rolls vertically to prevent stacking pallets.
  • Adequately prepare the application surface by removing any dust, debris, grease, leaves, or oil, and meticulously inspect for gaps, cracks, or irregularities that may hinder proper membrane adhesion.
  • Prior to installing the waterproofing material, apply a primer to the surface to optimize adhesion.

INSTALLATION

  • Thoroughly clean the surface and rectify any gaps or cracks. Verify that it is both
    level and dry before proceeding.
  • Apply a bitumen primer to the surface to improve the adhesion of the bitumen membrane.
  • Roll out the membranes, align them, and proceed to roll them tightly from both ends toward the center.
  • Heat both the base and underside of the material simultaneously to induce a slight flow of bitumen.
  • Heat the material and the base evenly across the entire width of the roll, applying
    extra heat to any overlapping sections.
  • Longitudinal overlaps should measure 100 mm, with end overlaps requiring a minimum of 150 mm.
