Unicorn Torch Membrane Sheet (APP) – Professional Roof Waterproofing
Unicorn Torch Membrane Sheet (APP) is a premium-quality APP-modified bituminous membrane manufactured for professional flat roof waterproofing applications. This heat-welded membrane delivers exceptional durability, flexibility, and weather resistance for large commercial and industrial roof areas.
The APP (Atactic Polypropylene) modification provides superior heat resistance, UV stability, and mechanical strength compared to conventional bituminous membranes. The factory-manufactured sheets are easy to install using a torch-on application method, creating a seamless, watertight barrier that protects buildings from water damage.
Available in various thicknesses and top finishes, Unicorn Torch Membrane Sheet is suitable for exposed and protected roof systems, providing reliable waterproofing performance for decades.

Surface Preparation
- Surface must be clean, dry, and structurally sound.
- Remove dust, debris, and loose particles.
- Apply primer to ensure optimal adhesion.
- Level uneven surfaces with appropriate repair mortar.
Application Procedure
Unroll the membrane and position it on the prepared surface. Use a gas torch to heat the underside of the membrane until the bitumen melts. Press firmly onto the substrate to ensure complete contact. Overlap joints by 80-100mm and seal edges with compatible sealant. For complex details, use appropriate flashing and detail membranes.
Storage
Store rolls upright in a cool, dry place away from direct sunlight and ignition sources. Shelf life is 12 months in original packaging.
Safety Precautions
- Wear protective clothing, gloves, and safety boots during installation.
- Use appropriate respiratory protection when heating the membrane.
- Keep fire extinguishers accessible during torch application.
- Follow local safety regulations for hot work operations.
- Refer to Material Safety Data Sheet (MSDS) before use.
